Description

{METHOD AND APPARATUS OF SIMULATING GARMENT}

The embodiments relate to a clothing simulation method and device.

Garments appear to be three-dimensional when worn by a person, but in reality, they are closer to two-dimensional because they are a combination of pieces of fabric cut according to a two-dimensional pattern. Since the fabric used as the material for clothing is flexible, its shape can change in various ways depending on the body shape or movement of the person wearing the clothing.

For example, when modifying style lines such as various types of cutting lines and/or sewing lines to reflect design elements in a three-dimensional garment, the length and/or area of two-dimensional patterns affected by the modified lines in the three-dimensional garment must also be reflected in the change.

The background technology described above is technology that the inventor possessed or acquired in the process of deriving the disclosure content of the present application, and cannot necessarily be said to be a publicly known technology disclosed to the general public prior to the present application.

According to one embodiment, the style line of a three-dimensional costume expressed in a three-dimensional space can be easily modified through a user interface.

According to one embodiment, the length and/or area of two-dimensional patterns constituting the three-dimensional garment can be deformed by propagating the deformation of a style line input through a three-dimensional interface in a three-dimensional space where the three-dimensional garment is expressed.

FIG. 1 is a drawing for explaining the effect of deformation of a three-dimensional garment through a user interface in a three-dimensional space according to one embodiment on two-dimensional patterns. Referring to FIG. 1, a drawing (110) showing a three-dimensional garment (101) according to one embodiment and a drawing (130) showing two-dimensional patterns (131, 133, 135, 137, 139) corresponding to the three-dimensional garment (101) are illustrated.

For example, a style line (113) of a three-dimensional costume (101) displayed in a three-dimensional space can be selected through a user interface (for example, see the user interface (1710) of FIG. 17) and can be deformed in an upward direction like the style line (115) or in a downward direction like the style line (117). The 'style lines' are lines that are visible on the three-dimensional costume (101), and may correspond to lines that indicate the style and/or silhouette of the three-dimensional costume (101), such as, for example, a sewing line that is visible on the three-dimensional costume (101) by sewing between two-dimensional patterns (131, 133, 135, 137, 139) that constitute the three-dimensional costume (101), an outline that indicates the silhouette of the three-dimensional costume (101), a cutting line added for the style of the three-dimensional costume (101), etc.

Hereinafter, the 'style line' refers to a three-dimensional line shown in the three-dimensional costume (101), and the 'continuous line' or 'line' may be understood to refer to a two-dimensional line that is continuous across two-dimensional patterns (131, 133, 135, 137, 139) that constitute the three-dimensional costume (101). The 'continuous line' may be understood as lines that are continuous and smoothly continuous across a plurality of two-dimensional patterns (131, 133, 135, 137, 139), such as, for example, a line that continuously connects the bottoms of the front and back patterns of a top, a line that continuously connects the sides of the front and back patterns of a top, and a line that continuously connects both cross-sections of a sleeve pattern. At this time, information about the continuous lines that are continuous across a plurality of patterns may be stored in a continuous line list (SLL) described below.

For example, an input may occur to change the position of the style line (113) of the 3D costume (101) upward, such as the style line (115), or downward, such as the style line (117). When an input for changing the style line (113) of the 3D costume (101) is received, the costume simulation device may change the position of the continuous line (140) at the bottom of the 2D patterns (133, 137) corresponding to the style line (113) among the 2D patterns (131, 133, 135, 137, 139) upward or downward in response to the changed style line (115, 117).

When a user input for changing a style line (113) shown in a three-dimensional costume (101) is received, the costume simulation device can reflect the change in the style line (113) to the continuous line (140) at the bottom of the two-dimensional patterns (133, 137) corresponding to the style line (113), thereby allowing the changed style line (115 or 117) of the three-dimensional costume (101) to be expressed identically in the two-dimensional patterns (133, 137).

According to one embodiment, when a user deforms a style line (113) of a three-dimensional garment (101) shown in a three-dimensional space through a three-dimensional interface into a style line (115) or a style line (117), the deformation of the style line (115) or the style line (117) is propagated to a two-dimensional continuous line (140) corresponding to the style line (113), thereby deforming the length and/or area of two-dimensional patterns (133, 137) associated with the continuous line (140), thereby naturally reflecting the deformation occurring in the three-dimensional garment (101) into the two-dimensional patterns (131, 133, 135, 137, 139).

When a user moves a style line (113) and/or an arbitrary point on the style line (113), the clothing simulation device simultaneously deforms, in addition to a two-dimensional continuous line (140) corresponding to the style line (113), continuous lines starting from a discontinuous point (non-smooth point) such as a sewing point on the continuous line (140) and/or continuous lines sewn together with continuous lines starting from a discontinuous point, thereby allowing the deformation of the style line (113) in the three-dimensional clothing (101) to be naturally reflected in the two-dimensional patterns (131, 133, 135, 137, 139). The discontinuous points will be described in more detail with reference to FIG. 5 below.

Each of the two-dimensional patterns (131, 133, 135, 137, 139) illustrated in the drawing (130) may correspond to each body part constituting the three-dimensional costume (101) illustrated in the drawing (110). For example, the right sleeve pattern (131) may correspond to the right arm part of the three-dimensional costume (101), and the front body pattern (133) may correspond to the front body part of the three-dimensional costume (101). The left sleeve pattern (135) may correspond to the left arm part of the three-dimensional costume (101), and the back body pattern (137) may correspond to the back body part of the three-dimensional costume (101). The neck collar pattern (139) may correspond to the neck part of the three-dimensional costume (101).

The two-dimensional patterns (131, 133, 135, 137, 139) may be virtual two-dimensional patterns modeled as a set of a plurality of polygons for the simulation of a three-dimensional costume (101). The two-dimensional patterns (131, 133, 135, 137, 139) include a plurality of pattern pieces, and each of the plurality of pattern pieces may be modeled as a polygonal mesh based on, for example, a body shape of a three-dimensional avatar. In this case, the polygonal mesh may include a plurality of polygons (for example, triangles or squares, etc.).

Although not shown in the drawing, the three-dimensional garment (101) and the two-dimensional patterns (131, 133, 135, 137, 139) may be composed of a mesh including a plurality of polygons. The mesh may be modeled in various ways according to embodiments. For example, the vertices of the polygons included in the mesh may be points having mass (point mass), and the sides of the polygons may be expressed as springs having elasticity that connect the masses. Accordingly, the three-dimensional garment (101) according to one embodiment may be modeled by, for example, a mass-spring model. The springs may have, for example, respective resistance values for stretch, shear, and bending depending on the properties of the fabric used.

Alternatively, the mesh can be modeled as a strain model. The polygons included in the mesh can be modeled as triangles, for example, or as polygons larger than a square. In some cases, when a three-dimensional volume needs to be modeled, the mesh can be modeled as a three-dimensional polyhedron.

The vertices of the polygon(s) included in the mesh can be moved by external forces such as gravity and internal forces such as stretch, shear, and bending. The clothing simulation device can obtain the displacement velocity and motion of each vertex by calculating the external and internal forces to obtain the force applied to each vertex. The movement of the clothing can be simulated through the movement of the vertices of the polygon(s) that constitute the mesh at each time motion.

For example, when a three-dimensional garment composed of a polygonal mesh is worn on a three-dimensional avatar, a natural three-dimensional virtual garment based on the laws of physics can be implemented. The vertices of the polygon(s) included in the mesh can move according to the action of external forces such as gravity and internal forces such as stretching, twisting, and bending. By calculating the external and internal forces to obtain the force applied to each vertex, the displacement and movement speed of each vertex can be obtained. In addition, the movement of the virtual garment can be simulated through the movement of the polygonal vertices of the mesh at each time step. When a two-dimensional pattern composed of a polygonal mesh is worn on a three-dimensional avatar, a natural three-dimensional virtual garment based on the laws of physics can be implemented.

A three-dimensional costume (101) according to one embodiment may include, for example, at least one of a virtual costume that fits the user's body dimensions, a virtual costume for a three-dimensional virtual character, and a virtual costume for a three-dimensional virtual avatar.

Fig. 2 is a flow chart illustrating a costume simulation method according to one embodiment. In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

Referring to FIG. 2, a clothing simulation device according to one embodiment can display a three-dimensional clothing with changed style lines through operations (210) to (250).

In operation (210), the clothing simulation device may receive an input for changing at least one style line among a plurality of style lines representing at least one of a style and a silhouette of the three-dimensional clothing through a user interface expressing the three-dimensional clothing. At this time, the input for changing the style line may be generated by the user selecting a point on the style line through a touch input using a finger, a touch pen input, a mouse click, etc., and moving the position of the selected point to a position such as above, below, left, or right of the style line, but is not necessarily limited thereto.

In operation (220), the clothing simulation device identifies at least one first continuous line (smooth line) that spans at least one two-dimensional pattern corresponding to a style line among a plurality of lines included in two-dimensional patterns corresponding to a three-dimensional clothing. The 'at least one first continuous line that spans at least one two-dimensional pattern corresponding to a style line' may correspond to a line (two-dimensional line) of two-dimensional patterns corresponding to a position of a style line of a three-dimensional clothing that is changed by a user's input. At this time, the first continuous line may be singular or plural.

For example, when an input for changing a style line (325) at the bottom of a three-dimensional garment (320) illustrated in the upper drawing (310) of FIG. 3 below is received, the garment simulation device can identify first continuous lines (345, 355) that span the two-dimensional patterns (340, 350) corresponding to the style line (325) among the multiple lines included in the two-dimensional patterns (340, 350, 360, 370, 380) illustrated in the drawing (330). At this time, the two-dimensional patterns (340, 350, 360, 370, 380) illustrated in the drawing (330) may correspond to the three-dimensional garment (320) illustrated in the drawing (310). The first continuous line (345) may correspond to the bottom line of the front pattern (340) of the top corresponding to the bottom style line (325) of the three-dimensional costume (320), and the first continuous line (355) may correspond to the bottom line of the back pattern (350) of the top corresponding to the bottom style line (325) of the three-dimensional costume (320).

In one embodiment, continuous lines (smooth lines) extending across two-dimensional patterns (340, 350, 360, 370, 380) corresponding to three-dimensional clothing (320) may include, but are not necessarily limited to, first type continuous lines corresponding to a style line selected by a user, second type continuous lines starting from a non-smooth point of the first type continuous lines, third type continuous lines sewn together with the second type continuous lines, and fourth type continuous lines sewn together with the first type continuous lines. The types of continuous lines according to one embodiment are described in more detail with reference to FIGS. 3 to 7 below.

In operation (230), the clothing simulation device can deform the first continuous line identified in operation (220) based on the input received in operation (210).

In operation (240), the clothing simulation device can deform at least one two-dimensional pattern by propagating the deformation of the first continuous line in operation (230) to at least one candidate line associated with the first continuous line. Here, the 'at least one candidate line associated with the first continuous line' can include, for example, at least one of a line symmetrical to the first continuous line selected by the user and/or a line sewn together with the first continuous line selected by the user.

The clothing simulation device may, for example, deform at least one of the two-dimensional patterns such that the shape of the three-dimensional clothing is substantially maintained, or may deform at least one of the two-dimensional patterns such that the shape of the three-dimensional clothing itself is deformed.

At least one candidate line may include at least one of a second continuous line corresponding to the first continuous line in a second pattern symmetrical to the first pattern including the first continuous line, a third continuous line starting from a non-smooth point of the first continuous line, and at least one sewing line of at least one third pattern connected by sewing to at least one of the first continuous line, the second continuous line and the third continuous line. The second pattern symmetrical to the first pattern may be understood as two-dimensional patterns corresponding to symmetrical human body parts, such as, for example, a left sleeve pattern symmetrical to a right sleeve pattern. In operation (240), the clothing simulation device may generate a continuous line list including, for example, the first continuous line deformed in operation (230) and at least one candidate line to which the deformation of the first continuous line is propagated. A 'continuous line list' is an ordered list of lines that are smoothly connected across multiple two-dimensional patterns, and may also be called a 'Smooth Line List (SLL).'

The continuous line list may include, but is not necessarily limited to, at least one of a first continuous line list including a first type of continuous lines including at least one of a continuous line selected by the user, a line symmetrical to the selected continuous line, and a line sewn together with the selected continuous line, a second continuous line list including a second type of continuous lines starting from a non-smooth point of the first type of continuous lines, a third continuous line list including a third type of continuous lines sewn together with the second type of continuous lines, and a fourth continuous line list including a fourth type of continuous lines sewn together with the first type of continuous lines.

In operation (240), the clothing simulation device can propagate the deformation of the first continuous line to deform at least one candidate line. At this time, the clothing simulation device can search for at least one candidate line to be deformed in association with the deformation of the first continuous line, and deform at least one of the searched candidate lines. The method of generating a continuous line list by searching for and deforming at least one candidate line by the clothing simulation device is described in more detail with reference to FIGS. 8 and 9 below.

In operation (240), the clothing simulation device can store information about the deformed candidate lines in a continuous line list. The clothing simulation device can deform a two-dimensional pattern based on the continuous line list.

The method by which the clothing simulation device deforms at least one two-dimensional pattern is described in more detail with reference to FIGS. 11 to 16 below.

In operation (250), the clothing simulation device can output at least one of the two-dimensional patterns transformed in operation (240) and a three-dimensional clothing with a style line changed corresponding to the transformed two-dimensional patterns.

Referring to FIG. 3, a drawing (310) showing a three-dimensional costume (320) according to one embodiment and a drawing (330) showing two-dimensional patterns (340, 350, 360, 370, 380) corresponding to the three-dimensional costume (320) are illustrated.

The clothing simulation device may receive, for example, an input for changing a style line (325) of a three-dimensional clothing (320) illustrated in the drawing (310). In response to receiving an input for changing a style line, the clothing simulation device may identify, as illustrated in the drawing (330), first continuous lines (345, 355) that extend across two-dimensional patterns (340, 350) corresponding to the style line (325) among continuous lines (smooth lines) included in two-dimensional patterns (340, 350, 360, 370, 380) corresponding to the three-dimensional clothing (320). At this time, the first continuous lines (345, 355) may correspond to a lower line of a front pattern (340) of a top and a lower line of a back pattern (350) of a top corresponding to a lower style line (325) of the three-dimensional clothing (320).

In this way, when a user selects one style line (e.g., style line (325)) to be changed in a three-dimensional costume (320), continuous lines (345, 355) on a two-dimensional pattern identified by the costume simulation device corresponding to the style line (325) selected by the user can be referred to as 'first type of continuous lines'. The first type of continuous lines can also be expressed as 'Picked SLL' in that they are continuous lines corresponding to the style line selected by the user.

For example, when an input is received to transform the position of a style line (325) of a three-dimensional costume (320) by moving it up or down, the costume simulation device can transform at least one two-dimensional pattern corresponding to the style line (325) by transforming the first continuous line (345, 355) corresponding to the style line (325) and propagating the transformation to at least one candidate line associated with the first continuous line (345, 355). The at least one candidate line associated with the first continuous line will be described in more detail with reference to FIG. 4 below.

FIG. 4 is a drawing for explaining the first type of continuous lines according to one embodiment. Referring to FIG. 4, a drawing (410) showing a three-dimensional costume (420) according to one embodiment and a drawing (430) showing two-dimensional patterns (440, 450, 460, 470, 480) corresponding to the three-dimensional costume (420) are illustrated.

For example, the clothing simulation device may receive a user's selection for a style line (425) of a three-dimensional clothing (420) illustrated in the drawing (410). In this case, the clothing simulation device may identify a first continuous line (445) corresponding to the style line (425) among the continuous lines of two-dimensional patterns (440, 450, 460, 470, 480) corresponding to the three-dimensional clothing (420), as illustrated in the drawing (430).

The clothing simulation device can deform the first continuous line (445) to reflect the change of the style line (425), while propagating the deformation of the first continuous line (445) to at least one candidate line associated with the first continuous line (445). At this time, the at least one candidate line associated with the first continuous line (445) can include, for example, a continuous line (447) that is symmetrical to the first continuous line (445) in a first pattern (440) including the first continuous line (445), a continuous line (455) sewn together with the first continuous line (445), and a continuous line (457) sewn together with the continuous line (447). Here, a continuous line (457) corresponding to the position of the first continuous line (445) in a second pattern (e.g., a two-dimensional pattern (450)) that is symmetrical to a first pattern (e.g., a two-dimensional pattern (440)) including a first continuous line (445) may be referred to as a 'second continuous line'.

In this way, the continuous lines selected by the user (Picked SLL) and the candidate lines associated with the continuous lines selected by the user can be referred to as 'continuous lines of the first type' or 'Picked SLL set'. The 'continuous lines of the first type' can be stored in the first continuous line list.

FIG. 5 is a drawing for explaining the second type of continuous lines according to one embodiment. Referring to FIG. 5, a drawing (510) showing a three-dimensional costume (520) according to one embodiment, a drawing (530) showing two-dimensional patterns (540, 550) including continuous lines (545, 555) corresponding to a style line (525) selected by a user in the three-dimensional costume (520), and a drawing (560) showing the second type of continuous lines (562, 564, 566, 568) starting from discontinuous points (541, 543) of the continuous line (545) and discontinuous points (551, 553) of the continuous line (555) are illustrated.

The clothing simulation device may, for example, receive a user's selection for a point of a style line (525) of a three-dimensional clothing (520) illustrated in the drawing (510). In this case, the clothing simulation device may identify first continuous lines (545, 555) that extend across two-dimensional patterns (540, 550) corresponding to the style line (525) among two-dimensional patterns corresponding to the three-dimensional clothing (520), as illustrated in the drawing (530). At this time, the first continuous lines (545, 555) may correspond to the 'first type of continuous lines' described above.

The clothing simulation device can identify continuous lines (second type continuous lines) starting from discontinuity points (541,543,551,553) of each of the first type of continuous lines (545,555). Here, the 'discontinuity point(s) of each of the first continuous lines' can be understood as point(s) where the continuity of the first continuous lines (545,555) ends when an angle between the first continuous lines (545,555) and the corresponding line is greater than or equal to a certain angle (e.g., 45 degrees or 90 degrees), or when the curvature of the line connecting the first continuous lines (545,555) and the corresponding line is greater than or equal to a certain value (e.g., 60 degrees).

In other words, in the two-dimensional pattern (540) illustrated in the drawing (560), the discontinuity points (541, 543) of the first continuous line (545) may correspond to both end points of the first continuous line (545), which are points where continuous lines in a vertical relationship with the first continuous line (545) meet. In addition, in the two-dimensional pattern (550), the discontinuity points (551, 553) of the first continuous line (555) may correspond to both end points of the first continuous line (555), which are points where continuous lines in a vertical relationship with the first continuous line (555) meet.

As shown in the drawing (560), the clothing simulation device can search for continuous lines (562, 564) starting from each of the discontinuous points (541, 543) of the first continuous line (545) of the two-dimensional pattern (540) and continuous lines (566, 568) starting from each of the discontinuous points (551, 553) of the first continuous line (555) of the two-dimensional pattern (550) as the second type of continuous lines.

In this way, a continuous line starting from a discontinuity point of a first type of continuous line can be called a 'second type of continuous line' or a 'pilar line'. The clothing simulation device can find a filler line starting from a discontinuity point of a continuous line in a two-dimensional pattern.

The second type of continuous lines starting from the discontinuity point of the continuous lines included in the 'First type of continuous lines' can be called 'Pilar SLL Set'. The second type of continuous lines can be stored in the second continuous line list.

FIG. 6 is a drawing for explaining a third type of continuous lines according to one embodiment. Referring to FIG. 6, a drawing (610) showing a three-dimensional garment (620) according to one embodiment and a drawing (630) showing two-dimensional patterns (650,670) including continuous lines (655,675) corresponding to style lines (625) of the three-dimensional garment (620) and continuous lines (645,665) sewn together with continuous lines (655,675) and continuous lines symmetrical to the continuous lines (655,675) are illustrated.

For example, when an input for changing the length or position of a style line (625) of a three-dimensional garment (620) is received, the garment simulation device can identify and deform first continuous lines (655, 675) that extend across at least one two-dimensional pattern (650, 670) corresponding to the style line (625), and propagate the deformation of the first continuous lines (655, 675) to continuous lines (657, 677) symmetrical to the first continuous lines (655, 675) and/or continuous lines (645, 665) sewn together with the second type of continuous lines (655, 657, 675, 677), thereby deforming the two-dimensional pattern.

The clothing simulation device can propagate the deformation of the first continuous lines (655,675) to the continuous lines (645,665) of the two-dimensional patterns (640,660) connected by sewing with the first continuous lines (655,675). Information about the first continuous lines (655,675) and the continuous lines (645,665) sewn together with the first continuous lines (655,675) can be included in the continuous line list described above.

For example, if the first continuous lines (655,657,675,677) correspond to the second type of continuous lines or filler lines described above, the continuous lines (645,665) sewn together with the first continuous line (655,657,675,677) may be called 'third type of continuous lines'. The third type of continuous lines sewn together with the second type of continuous lines may be called 'Pilar-Sewn SLL Set'. The third type of continuous lines may be included in the third continuous line list.

As will be described in more detail below, when the third type of continuous lines (645,665) are sewn together with the second type of continuous lines, the length ratio of the second type of continuous lines (655,675) may also be changed as the area of the two-dimensional patterns (650,670) including the second type of continuous lines (655,675) is changed. The clothing simulation device calculates the length change ratio of the continuous lines ('second type of continuous lines') (655,675) corresponding to the two-dimensional patterns (650,670) of which the area has been changed, and can change the length ratio of the continuous lines (645,665) sewn together with the continuous lines corresponding to the two-dimensional patterns (650,670) of which the area has been changed based on the length change ratio of the second type of continuous lines (655,675).

FIG. 7 is a drawing for explaining the fourth type of continuous lines according to one embodiment. Referring to FIG. 7, a drawing (710) showing a three-dimensional garment (720) according to one embodiment, and a drawing (730) showing the fourth type of continuous lines (732736) sewn together with a first type of continuous line (734) corresponding to a style line (725) selected by a user in the three-dimensional garment (720) are illustrated.

The clothing simulation device may, for example, receive a user's input for changing a style line (725) of a three-dimensional clothing (720) illustrated in the drawing (710). In this case, the clothing simulation device may identify a first continuous line (734) corresponding to the style line (725) among continuous lines (732, 734, 736) of two-dimensional patterns (731, 733, 735) corresponding to the style line (725) of the three-dimensional clothing (720), as illustrated in the drawing (730).

When an input for changing the length or position of the style line (725) of the three-dimensional garment (720) is received, the garment simulation device may change the position and/or length of the first continuous line (734) according to the change of the style line (725), while propagating the change of the first continuous line (734) to at least one candidate line associated with the style line (725). At this time, among the at least one candidate line associated with the style line (725), for example, the continuous line (734) of the two-dimensional sleeve pattern (733) corresponding to the style line (725) may correspond to the first type of continuous line, and the continuous line (732) of the front pattern (731) and the continuous line (736) of the back pattern (735) sewn together with the continuous line (734) may correspond to the fourth type of continuous lines sewn together with the first type of continuous line. The 'fourth type of continuous line' corresponds to a continuous line that is sewn together with the first type of continuous lines that are transformed in relation to the continuous line selected by the user, and may be called 'Picked-Sewn SLL'. The 'Picked-Sewn SLL' may correspond to a set of continuous lines that includes all continuous lines included in the Picked SLL Set and all lines that are sewn.

Fig. 8 is a flowchart illustrating a method for generating a continuous line list through a candidate line search according to one embodiment. In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

Referring to FIG. 8, a process of generating a continuous line list through operations (810) to (840) of a clothing simulation device according to one embodiment is illustrated.

In operation (810), the clothing simulation device can set the first continuous line as the current line.

In operation (820), the clothing simulation device can set a first direction from a starting point where an input for changing a style line in the current line set in operation (810) is received to an end point opposite to the starting point as a search direction.

In operation (830), the clothing simulation device can search for the next continuous line of the current line based on the current line set in operation (810) and the search direction set in operation (820). An example of how the clothing simulation device searches for the next continuous line of the current line is as follows.

The garment simulation device can, for example, set at least one of a next line connected to the current line and a line connected to the current line through sewing within a two-dimensional pattern including the current line as a candidate line of the next continuous line based on the current line and the search direction. The garment simulation device can determine the continuity (smoothness) between the candidate line and the current line among the candidate lines of the next continuous line. The method by which the garment simulation device determines the continuity between the candidate line and the current is described in more detail with reference to FIG. 9 below.

The clothing simulation device can search for the candidate line as the next continuous line based on continuity. For example, the clothing simulation device can select the line that most smoothly connects to the current line among the candidate lines, in other words, the line showing the highest continuity, as the next continuous line.

In operation (840), the costume simulation device can add the next continuous line searched in operation (830) to the continuous line list.

FIG. 9 is a drawing for explaining a method for generating a continuous line list according to one embodiment. Referring to FIG. 9, a drawing (900) for explaining a method for generating a continuous line list by finding continuous lines included in two-dimensional patterns (910, 930) according to one embodiment is illustrated.

A list of continuous lines according to one embodiment may include a first continuous line modified by a user and at least one candidate line to which the modification of the first continuous line is propagated.

For example, let's say that a point selected by a user in a three-dimensional garment corresponds to a point (911) on a continuous line (913) at the lower right of a two-dimensional pattern (910). The garment simulation device can receive as input whether a start point or an end point of a continuous line is selected and output a continuous line list, which is a sequential list of continuous lines (915, 933, 935) that are continuously connected to the continuous line (913) including the selected point (911).

For example, when a point (911) corresponding to the starting point of a continuous line (913) of a two-dimensional pattern (910) is selected, the clothing simulation device can mark a 'visit' on the continuous line (913) and set the continuous line (913) as the current line.

The clothing simulation device can set a search direction as a first direction (e.g., leftward direction) from a starting point (911) where an input is received in a current line (e.g., continuous line (913)) to an end point on the opposite side. Based on the current line and the search direction, the clothing simulation device can search for a next smooth line (e.g., continuous line (915)) of the current line (continuous line (913)), and add the searched smooth line (continuous line (915)) to the continuous line list.

The clothing simulation device can mark the next continuous line as 'visited' if there is a next continuous line to be searched, set the next continuous line as the current line, and sequentially add it to the continuous line list. The clothing simulation device can repeat the operation of searching for the next continuous line of the current line according to the search direction (e.g., leftward direction).

More specifically, the way the costume simulation device searches for the next continuous line of the current line is as follows.

The clothing simulation device can set at least one of a next continuous line (continuous line (915)) and lines connected to the current line (continuous line (913)) through sewing (e.g., continuous line (933) and continuous line (935)) within a two-dimensional pattern (910) including the current line (continuous line (913)) as a candidate line of the next continuous line, based on a current line (e.g., continuous line (913)) and a search direction (e.g., leftward direction). Here, the 'current line and sewn-connected line(s)' will be described in more detail with reference to FIG. 10 below.

The clothing simulation device can determine the continuity (smoothness) between the candidate line (continuous line (933) and continuous line (935)) of the next continuous line and the current line (continuous line (913)). For example, if the candidate line and the current line (continuous line (913)) are continuous lines that are connected within the same two-dimensional pattern, the clothing simulation device can determine the continuity between the candidate line and the current line based on the angle between the candidate line and the current line or the curvature of the continuous line connecting the candidate line and the current line.

Alternatively, the clothing simulation device may determine the continuity between the candidate line (continuous line (933)) and the current line (continuous line (913)) based on the angle between the candidate line (continuous line (933)) and the current line (continuous line (913)) connected by sewing or the curvature of the candidate line (continuous line (933)) and the current line (continuous line (913)) connected by sewing, if the candidate line (continuous line (933)) and the current line (continuous line (913)) are continuous lines connected by sewing. At this time, the 'continuity between the candidate line and the current line' may be determined based on at least one of whether the angle between the candidate line and the current line is less than or equal to a certain angle (e.g., 15 degrees) or whether the curvature of the line connecting the candidate line and the current line is less than or equal to a certain value. The clothing simulation device may search for the candidate line (continuous line (933)) as the next continuous line based on the continuity. The clothing simulation device can search for a continuous line (e.g., continuous line (933)) that has the highest continuity with the current line among the candidate lines of the next continuous line as the next continuous line.

In this way, the clothing simulation device can repeatedly search for the first next continuous line of the current line (continuous line (913)) along the first direction (leftward direction), and then repeatedly search for the second next continuous line of the current line (continuous line (913)) along the second direction (rightward direction) opposite to the first direction.

The clothing simulation device can search for the next continuous line (continuous line (915)) in the opposite direction (rightward direction) of the search direction and search for the next continuous line again and add it to the continuous line list. Accordingly, in addition to the continuous line (913) and the continuous line (915) stored in the continuous line list, the continuous line (933) at the lower left and the continuous line (935) at the lower right of the two-dimensional pattern (930) can be sequentially stored in the continuous line list. The clothing simulation device can terminate the operation if there is no next continuous line to be searched.

FIG. 10 is a drawing for explaining a sewn-connected line according to one embodiment. Referring to FIG. 10, two-dimensional patterns (1010, 1030) including lines (1015, 1035) connected through sewing are illustrated according to one embodiment.

For example, if one of the following lines of line A is sewn to one of the following lines of line B, then line A and line B can be said to have a 'sewn-connected' relationship.

In Fig. 10, the line (1015) of the pattern (1010) and the line (1035) of the pattern (1030) that are sewn together may correspond to a relationship in which they are connected to each other through sewing.

FIG. 11 is a flow chart illustrating a method for a clothing simulation device according to one embodiment to transform at least one two-dimensional pattern. In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

Referring to FIG. 11, a process of generating a continuous line list through operations (1110) to (940) of a clothing simulation device according to one embodiment is illustrated.

In operation 1110, the clothing simulation device can add the deformed first continuous line to the continuous line list.

In operation 1120, the garment simulation device can add to the list of continuous lines a continuous line symmetrical to the first continuous line, and a length change of the first continuous line that is deformed to a continuous line sewn together with the first continuous line.

In operation 1130, the clothing simulation device can perform operations 1131 to 1135 below in response to a filler line starting from a discontinuity point of each of the continuous lines included in the continuous line list.

In operation 1131, the clothing simulation device can remove a corresponding filler line from the continuous line list while acquiring the corresponding filler line. Operation 1131 may be referred to as 'Operation S1'.

In operation 1133, the clothing simulation device can apply an area deformation due to deformation of the corresponding filler line to a sewing line that is not yet deformed among the lines connected to the corresponding filler line by sewing, and add it to the continuous line list. Operation 1133 can be referred to as 'Operation S2'.

In operation 1135, the garment simulation device can apply an area deformation due to deformation of a filler line corresponding to a continuous line that is symmetrical to the sewing line and add it to the continuous line list. Operation 1135 can be referred to as 'Operation S3'.

The clothing simulation device can repeatedly perform operations 1131 to 1135 in operation 1130 until there are no filler lines remaining in the continuous line list.

The garment simulation device can propagate the deformation of the continuous lines by repeating the operations in the order of Picked SLL -> Pilar SLL -> Pilar-Sewn SLL -> ..., for example, until no new continuous lines are found.

In this way, the clothing simulation device can change at least one of the length and area of the two-dimensional pattern by propagating the deformation of the first continuous line to at least one candidate line associated with the first continuous line based on the continuous line list. The method by which the clothing simulation device changes at least one of the length and area of the two-dimensional pattern is described in more detail with reference to FIG. 12 and FIG. 15 below.

FIGS. 12a and 12b are drawings for explaining the deformation direction according to one embodiment.

As described above, the clothing simulation device can change at least one of the length and area of the two-dimensional pattern by propagating the deformation of the continuous line to candidate lines associated with the continuous line based on the continuous line list.

The garment simulation device can, for example, propagate the length change of the first type of continuous lines included in the first continuous line list to at least one candidate line associated with the first type of continuous lines. The garment simulation device can propagate the area change due to the deformation of the second type of continuous lines starting from the discontinuity point of the first type of continuous lines to at least one candidate line associated with the second type of continuous lines. Alternatively, the garment simulation device can propagate the length change of the third type of continuous lines sewn together with the second type of continuous lines to at least one candidate line associated with the third type of continuous lines.

Referring to FIG. 12a, a drawing is shown showing a case where a two-dimensional pattern according to one embodiment is deformed in a tangent direction to a first continuous line.

For example, when an input for deforming a style line (1215) of a three-dimensional garment (1210) occurs in a direction tangent to a continuous line (first continuous line), that is, in an inward direction (1220) or an outward direction (1230) horizontal to the style line (1215), the garment simulation device can deform a two-dimensional pattern corresponding to the input in a tangent direction tangent to the first continuous line. Depending on the deformation in the tangent direction tangent to the first continuous line, the lengths of the lower parts of the front two-dimensional pattern and the back two-dimensional pattern corresponding to the style line (1215) may change.

Also, referring to FIG. 12b, a drawing is shown showing a case where a two-dimensional pattern according to one embodiment is deformed in a normal direction orthogonal to a first continuous line, that is, in a normal direction.

For example, when an input for deforming a style line (1215) of a three-dimensional garment (1210) occurs in a direction orthogonal to a continuous line (first continuous line), that is, in an upward direction (1240) or downward direction (1250) perpendicular to the style line (1215), the garment simulation device can deform a two-dimensional pattern corresponding to the input in a normal direction orthogonal to the first continuous line. At this time, the garment simulation device can regard second type continuous lines starting from a discontinuity point of first type continuous lines including at least one of a continuous line selected by a user, a line symmetrical to the selected continuous line, and a line sewn together with the selected continuous line as first type continuous lines and change their lengths. The areas of the front two-dimensional pattern and the back two-dimensional pattern corresponding to the style line (1215) can be changed according to the change in the length in the normal direction orthogonal to the first continuous line.

When a length change in the normal direction occurs, the clothing simulation device can, for example, regard the Pilar SLL Set as the Picked SLL Set and change the length. At this time, the method of propagating the deformation can be applied equally to cases where the two-dimensional pattern is deformed in the tangent direction and in the normal direction.

FIGS. 13a and 13b are drawings for explaining a method of deforming continuously lines as a whole and a method of deforming continuously lines partially according to one embodiment.

Referring to FIG. 13a, drawings (1301, 1302) are illustrated showing an example in which continuous lines are deformed as a whole when an arbitrary point on a style line (1315) of a three-dimensional garment (1310) according to one embodiment is selected.

For example, let's say that a user input occurs to transform a style line (1315) at a continuous point except for the discontinuous points at both ends of the style line (1315) in the three-dimensional garment (1310) illustrated in the drawing (1301). At this time, if the user selects an arbitrary point that is not discontinuous on the style line or line of the three-dimensional garment (1310), a continuous line corresponding to the selected point can be selected in a two-dimensional pattern corresponding to the selected point.

When an input for deforming a style line (1315) occurs at a continuous point of a first continuous line, the clothing simulation device can deform the entire continuous line(s) corresponding to the input in two-dimensional patterns corresponding to the three-dimensional clothing (1310).

The clothing simulation device can deform the entire continuous line(s) corresponding to the input when a horizontal deformation occurs, such as line (1320), at a continuous point of the style line (1315) illustrated in the drawing (1301), or a vertical deformation occurs, such as line (1330), at a continuous point of the style line (1315) illustrated in the drawing (1302).

In other words, the user can deform the continuous lines corresponding to the style line (1315) as a whole, such as the line (1320) and/or the line (1330) illustrated in the drawing (1302), by picking any location except for both ends of the style line (1315) of the 3D costume (1310).

Referring to FIG. 13b, drawings (1303, 1304) are shown showing an example in which continuous lines are partially deformed when a non-smooth point (1340) of a style line (1315) is selected in a three-dimensional garment according to one embodiment.

Let's say that a user input for changing a style line (1315) occurs at a discontinuous point (1340), such as a sewing point located on a style line (1315) in a three-dimensional garment (1310) illustrated in the drawing (1303). If the input for changing the style line (1315) occurs at the discontinuous point (1340), the garment simulation device can change some continuous lines corresponding to the input in two-dimensional patterns corresponding to the three-dimensional garment (1310). Here, the input for changing the style line 'occurs at the discontinuous point' can be understood to encompass all occurrences of the input at the discontinuous point (1340) and points adjacent to the discontinuous point (1340). 'Points adjacent to the discontinuous point' can be understood as points located adjacent to the discontinuous point (1340) enough to be recognized as the discontinuous point (1340) by the naked eye in the three-dimensional garment displayed on the screen.

The clothing simulation device can deform some continuous lines corresponding to the input in two-dimensional patterns, that is, some continuous lines including the discontinuous point (1340), when deformation occurs in the left and right horizontal directions (1343) at a discontinuous point (1340) of the style line (1315) as in the drawing (1303), or when deformation occurs in the up and down vertical directions (1345) at a discontinuous point (1340) of the style line (1315) as in the drawing (1304).

A user can partially deform continuous lines corresponding to a style line (1315) by picking a discontinuous point (1340) on a style line (1315) of a three-dimensional costume (1310).

FIGS. 14A and 14B are diagrams for explaining a method of modifying the length of all continuous lines corresponding to an input according to one embodiment and a method of modifying the length of some continuous lines.

Referring to FIG. 14a, a drawing (1401) is shown showing an embodiment of changing the length of entire continuous lines (1411, 1413, 1421, 1423) of two-dimensional patterns (1410, 1420) corresponding to an input for changing a style line of a three-dimensional garment according to one embodiment.

For example, if the user's input occurs at a point other than a discontinuous point on a continuous line, such as in the drawing (1301) or drawing (1303) of FIG. 13a, the clothing simulation device can deform the entire continuous line corresponding to the input in the two-dimensional pattern. The clothing simulation device can deform all of the continuous lines (1411, 1413, 1421, 1423) of the two-dimensional patterns (1410, 1420) corresponding to the input at the same length ratio.

For example, when a change in the length of a continuous line (1411) occurs in a two-dimensional pattern (1410), the clothing simulation device can change at least one candidate line associated with the continuous line (1411) whose length has been changed (for example, a continuous line (1413) that is a next line connected to the continuous line (1411), a continuous line (1423) corresponding to the continuous line (1411) in a two-dimensional pattern (1420) that is symmetrical to the two-dimensional pattern (1410) including the continuous line (1411), a continuous line (1421) connected to the continuous line (1413) by sewing) to the entirety of the changed continuous line (1411) at the same length ratio.

Referring to FIG. 14b, a drawing (1403) is shown showing an embodiment of modifying the length of some continuous lines of two-dimensional patterns (1430, 1440) corresponding to an input for changing a style line of a three-dimensional garment according to one embodiment.

When the user's input occurs at a discontinuous point, such as a sewing point on a continuous line, as in, for example, the drawing (1303) or drawing (1304) of FIG. 13B, the clothing simulation device can deform some of the continuous lines corresponding to the input in the two-dimensional pattern. The clothing simulation device can deform some of the continuous lines by dividing the continuous lines corresponding to the user's input in the three-dimensional clothing into segments (e.g., segments (1435)) of two-dimensional pattern units and reducing or expanding the length of the segment (1435) including the user's selected point (e.g., discontinuous point (1431)) to the left or right.

The clothing simulation device divides the continuous line into segments of two-dimensional pattern units based on discontinuous points of the continuous line, and can change the length of the segment corresponding to the changed position of the discontinuous point in the segment including the discontinuous point.

For example, an input may occur by a user to change a discontinuous point (1431) of a two-dimensional pattern (1430) to a position (1433). In this case, the clothing simulation device may change the length of the segment (1435) including the discontinuous point (1431) by a length corresponding to the changed position (1433) of the discontinuous point (1431).

The clothing simulation device can also deform a segment (1445) of a two-dimensional pattern (1440) that is sewn together with a segment (1435) of a two-dimensional pattern (1430) in the same manner as the segment (1435). The clothing simulation device can deform the length of the segment (1445) including the discontinuous point (1441) by a length corresponding to the changed position (1443) of the discontinuous point (1441). At this time, the length of the deformed segment (1445) can be the same as the deformed length of the segment (1435).

FIGS. 15A and 15B are diagrams for explaining a method of changing the area of a two-dimensional pattern corresponding to continuous lines according to one embodiment.

Referring to FIG. 15a, a drawing (1501) is shown showing a first type of continuous lines (1510, 1520) in which a user's input occurs according to one embodiment, and a second type of continuous lines ('filler lines') (1512, 1514, 1522, 1524) starting from discontinuity points (1511, 1513, 1521, 1523) of the continuous lines (1510, 1520). Referring to FIG. 15b, a drawing (1503) is shown showing continuous lines (1530, 1540) whose lengths are changed by a user's input, and an area of a two-dimensional pattern including the continuous lines (1530, 1540) is changed according to the change in the length of the continuous lines (1530, 1540).

In Fig. 15a, when the length of the continuous lines (1510, 1520) changes due to a user's input, the positions of the filler lines (1512, 1514, 1522, 1524) may change to reflect the change in the length of the continuous lines (1510, 1520). When the positions of the filler lines (1512, 1514, 1522, 1524) change, the area of the two-dimensional pattern including the filler lines (1512, 1514, 1522, 1524) may change, as in Fig. 15b. At this time, the clothing simulation device can calculate the position displacement value ('first position displacement value') of the points ('first points') that overlap with the continuous line ('first continuous line') whose length has been changed among the points ('second points') located on the filler lines (1512, 1514, 1522, 1524). At this time, the clothing simulation device can interpolate the positions of the remaining points, excluding the points that overlap with the first type of continuous line whose length has been changed, based on the length change ratio of the first type of continuous line.

More specifically, the clothing simulation device can calculate first positional displacement values of first points, which overlap with the first continuous line whose length has been changed, among second points located on at least one of the second type of continuous lines starting from a discontinuity point of the first continuous line. The clothing simulation device can calculate second positional displacement values of the remaining points, excluding the first points, among the second points located on the second type of continuous lines, based on a length change ratio of the first continuous line whose length has been changed. The clothing simulation device can change an area of the two-dimensional pattern based on the first positional displacement value and the second positional displacement value.

FIGS. 16A and 16B are diagrams for explaining a method of deforming both sides and one side of a two-dimensional pattern corresponding to continuous lines according to one embodiment. Referring to FIG. 16A, a drawing (1601) showing a three-dimensional garment (1610) according to one embodiment and a drawing (1603) showing an embodiment of deforming corresponding two-sided sleeve patterns (1620, 1640) among two-dimensional patterns (1620, 1630, 1640, 1650) corresponding to the three-dimensional garment (1610) are illustrated.

For example, when a user clicks and drags a sleeve line (1615) in a three-dimensional garment (1610) illustrated in the drawing (1601) with a mouse, the garment simulation device can also deform the sleeve line (1615) and the sleeve line (1617) corresponding to the sleeve line (1615), that is, the sleeve line on the opposite side of the sleeve line (1615). The garment simulation device can propagate the deformation of the patterns on both sides corresponding to the sewn SLL of the picked SLL as well as the picked SLL Set.

When an input for transforming a style line (1615) is received through selection of a primary user interface for at least one style line, the clothing simulation device can transform both one side (e.g., a left sleeve portion) where the input occurred and the other side (e.g., a right sleeve portion) corresponding to the one side in the two-dimensional patterns (1620, 1630, 1640, 1650) illustrated in the drawing (1603). The clothing simulation device can deform at least one of a first type of continuous line including at least one of a continuous line (1641) of a left sleeve portion selected by a user from among the two-dimensional patterns shown in the drawing (1603), a continuous line (1621) of a right sleeve portion symmetrical to the selected continuous line (1641), and a line (1633, 1651) sewn together with the selected continuous line (1641), and a fourth type of continuous line (1631, 1653) sewn together with the at least one of the first type of continuous lines (1641, 1621, 1633, 1651), in response to an input.

Referring to FIG. 16b, a drawing (1605) showing a three-dimensional costume (1660) according to one embodiment and a drawing (1607) showing two-dimensional patterns (1670, 1680, 1690) corresponding to the three-dimensional costume (1660) are illustrated.

For example, a user may select a sleeve line (1665) in a three-dimensional garment (1660) illustrated in the drawing (1605) by clicking once with the mouse, and may then select and drag a continuous line (1665) in a secondary user interface (1667) displayed on the screen. In this case, the garment simulation device may deform the sleeve line (1665) on one side where the input occurred.

If the input occurs through a selection in the secondary user interface (1667) through selection of at least one style line (e.g., sleeve line (1665)) illustrated in the drawing (1605), the garment simulation device may deform one sleeve line (1665) from which the input occurred in the two-dimensional patterns (1670, 1680, 1690) illustrated in the drawing (1607). In the case of deforming one side, the garment simulation device may not propagate the deformation for the Picked SLL Set to the sewn SLL of the Picked SLL.

The clothing simulation device can deform a first type of continuous lines corresponding to an input, including a continuous line (1671) selected by a user and continuous lines (1681, 1691) sewn together with the selected continuous line (1671).
