Description

Method, device, equipment and storage medium for drawing primitive

Technical Field

Example embodiments of the present disclosure relate generally to the field of computers and, more particularly, to a method, apparatus, device, and computer-readable storage medium for drawing primitives.

Background

In a scenario of drawing a planar layout, in order to truly reflect the spatial structure and area, the position orientation, the use function, and other information of each subspace, it is generally necessary to represent various elements in the space by using corresponding primitives according to the measurement data of the space. Currently, floor plans can be produced by means of computers. However, when drawing some elements in the planar layout, the primitives are still adjusted by directly stretching the picture of the elements. This will inevitably cause errors between the dimensions and proportions in the floor plan and the measurement data.

While certain embodiments of the present disclosure are illustrated in the accompanying drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.

It will be appreciated that the data involved in the subject technology, including but not limited to the data itself, the acquisition or use of the data, should comply with the requirements of the corresponding laws and regulations and related regulations.

In the description of the embodiments of the present disclosure, the terms "first", "second", and the like are used merely for distinguishing between different elements, objects, targets, units, and do not imply an order or difference in time, space, priority of the elements, objects, targets, units.

It is understood that before the technical solutions disclosed in the embodiments of the present disclosure are used, the user should be informed of the type, the use range, the use scene, etc. of the personal information related to the present disclosure and obtain the authorization of the user through an appropriate manner according to the relevant laws and regulations.

For example, in response to receiving an active request from a user, a prompt message is sent to the user to explicitly prompt the user that the requested operation to be performed would require the acquisition and use of personal information to the user. Thus, the user can autonomously select whether to provide personal information to software or hardware such as an electronic device, an application program, a server, or a storage medium that performs the operations of the disclosed technical solution, according to the prompt information.

As an optional but non-limiting implementation manner, in response to receiving an active request of the user, the prompt information is sent to the user, for example, a pop-up window manner may be used, and the prompt information may be presented in a text manner in the pop-up window. In addition, a selection control for providing personal information to the electronic device by the user selecting "agree" or "disagree" can be carried in the pop-up window.

It is understood that the above notification and user authorization process is only illustrative and is not intended to limit the implementation of the present disclosure, and other ways of satisfying the relevant laws and regulations may be applied to the implementation of the present disclosure.

An exemplary application scenario for floor plan is a house floor plan, where elements may include walls, doors, windows, stairs, etc. The house layout is used for reflecting house area, house layout, wall distribution, room orientation, functional partition, house lighting and other information. In general, when a house layout is drawn, it is necessary to refer to images taken at a house site and measured data. However, when some elements in the plane layout are drawn, the corresponding primitives cannot be generated by the computer, and the primitives are adjusted by scaling the picture equally.

For example, when drawing a straight ladder, the ladder size can only be adjusted by scaling the picture equally. This approach does not allow the step number and width to be dynamically adjusted to the premises. Further, when a picture is stretched, picture distortion may be caused. In addition to house-type drawings, other scenes for drawing spatial layout drawings face similar problems. Therefore, it is desirable to improve the manufacturing process of the spatial layout so as to flexibly adjust various primitives in the spatial layout.

Embodiments of the present disclosure propose schemes for drawing primitives. The method can parameterize the attribute of the space element, so that the size and the shape of the graphic element in the space layout can be accurately adjusted according to the parameter. In addition, the scheme also provides a user interface for drawing the primitives and supports adjusting the primitives in a flexible interactive manner. In this way, the manufacturing efficiency of the spatial layout diagram can be improved, the accuracy of the spatial layout diagram is guaranteed, and the presentation effect is enhanced.

Embodiments of the present disclosure will be described hereinafter in conjunction with the scenario of a house layout. However, it should be understood that the house floor plan is only one of many application scenarios for embodiments of the present disclosure, and that embodiments of the present disclosure are equally applicable to other scenarios, such as engineering, city planning, traffic management, and so forth. Accordingly, the scope of embodiments of the present disclosure is not so limited.

Furthermore, embodiments will be described below with reference to several example states of a User Interface (UI). It should be understood that these UIs and interactions are merely illustrative and that a variety of interface designs and interaction styles may exist in practice. Additionally, the controls included in these UIs may be implemented using any currently known or later developed UI elements and techniques. Further, the type, form, manner of operation, layout, arrangement in the UI, etc. of these controls are illustrative and not intended to limit the scope of the present disclosure in any way.

FIG. 1 illustrates a schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented. In the example environment 100, the terminal device 110 may be used to make a floor plan for a target space. In some embodiments, the target space may be a house, a building, or the like. Accordingly, the floor plan may be a house floor plan, a building floor plan, or the like. Of course, in other embodiments, the target space may be any other suitable physical or virtual space. Accordingly, embodiments of the disclosure are not limited in this regard.

In some embodiments, live-action pictures, modeling images used to make floor plans may be taken or generated by a user through terminal device 110. In other embodiments, the live action pictures or modeling images may come from any other data source. Further, in some embodiments, measurement data for the target space may be uploaded by the user 102 or may be obtained from any other data source.

In some embodiments, the terminal device 110 may be installed with an application 120 for making floor plans. In some embodiments, the application 120 may present a user interface for user-making floor plans to the user 102, as will be described in detail below in conjunction with fig. 2, 3A-3D, and 4A-4D.

The terminal device 110 may be any type of mobile terminal, fixed terminal, or portable terminal including a mobile handset, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, media computer, multimedia tablet, Personal Communication System (PCS) device, personal navigation device, Personal Digital Assistant (PDA), audio/video player, digital camera/camcorder, positioning device, television receiver, radio broadcast receiver, electronic book device, gaming device, or any combination of the preceding, including accessories and peripherals of these devices, or any combination thereof. In some embodiments, terminal devices 110 and 120 can also support any type of interface to the user (such as "wearable" circuitry, etc.).

The terminal device 110 may communicate with a remote device (not shown) to enable storage, updating and access to floor plan data for the target space. For example, the remote device may be used to extend the storage and processing capabilities of terminal device 110. In some embodiments, the remote device may be various types of computing systems/servers capable of providing computing power, including but not limited to mainframes, edge computing nodes, electronic devices in a cloud environment, and so forth.

Herein, the picture, the measurement data, and the floor plan of the target space may have any data format. Embodiments of the present disclosure are not limited in this respect. It should also be understood that the description of the structure and functionality of the environment 100 is for exemplary purposes only and is not meant to imply any limitation as to the scope of the disclosure.

Reference will now be made to fig. 2, which illustrates a flow diagram of a process 200 for drawing primitives, in accordance with some embodiments of the present disclosure. Process 200 may be implemented at terminal device 110. Of course, process 200 may be implemented at any suitable device. For ease of discussion, the process 200 will be described with reference to the environment 100 of fig. 1.

In the example of fig. 2, the user 102 makes a floor plan for the target space through the terminal device 110. As previously described, the target space may be a real space or a virtual space, and has therein elements capable of reflecting attributes of the structural layout, area, position, orientation, area, usage function, etc. of the space, including but not limited to stairs, doors, windows, walls, etc. The elements may be represented in the floor plan by corresponding primitives, and the proportion of the primitives in the floor plan is substantially the same as the proportion of the elements in the target space.

In process 200, terminal device 110 adjusts for the primitives in the map. By way of example, user 102 may adjust the size, angle, shape, etc. of various graphical elements in the layout drawing through a user interface of application 120 presented in terminal device 110.

Fig. 3A-3D illustrate schematic diagrams of user interfaces for drawing primitives in which a straight ladder primitive is presented and has a first number of sub-primitives representing rectangular ladders of a straight ladder, according to some embodiments of the present disclosure. As shown in FIG. 3A, the user interface 300 includes an element control 310, and the user 102 can activate a child control of the element control 310 representing a corresponding element by a gesture, such as a click, a drag, or the like, to add a primitive to the layout. In the example of FIG. 3A, a first graphical element 320 is added to the layout diagram by activating a child control representing a vertical ladder.

The user interface 300 also includes controls 312 for manipulating the layout, and respective operations on the layout can be triggered by activating respective ones of the controls 312. It should be understood that the child controls in control 312 are merely exemplary. In practice, different child controls than those in the user interface 300 may be provided as desired, and this disclosure is not repeated in this regard.

The user interface 300 also includes an information area 330 and an operation area 340 for the target element. Information area 330 presents the properties and size parameters of the target element and includes type control 331 and size controls 333, 335, 337, and 338. The type of primitive currently being rendered may be altered by activating the type control 331. The size parameters of length 332, width 334, angle 336, etc. of the primitive may be adjusted accordingly by activating controls 333, 335, 337, and 338. In the example of fig. 3A, controls 333, 335, and 337 are illustrated as slider controls, and user 102 resizes the corresponding dimensional parameter by dragging the slider left or right. In addition, control 338 provides several child controls for a predetermined angle. The user 102 may set the first graphical element 320 to a corresponding predetermined angle by activating one of the child controls of the control 338. The operation region 340 includes controls 341 to 343 for performing operations of left-right mirroring, inside-outside mirroring, deleting elements, and the like with respect to the first primitive.

It should be understood that the types and numbers of properties, operations, and controls presented for different target elements may be different. Accordingly, the layout of the user interface 300 and the controls therein are merely illustrative and are not intended to limit the scope of the present disclosure in any way.

At block 210, terminal device 110 detects for an input that changes a first size of a first primitive in a layout diagram in a target space. In some embodiments, the input may be a touch gesture to a screen of terminal device 110, including, but not limited to, a drag gesture, a pinch gesture, and the like. Additionally or alternatively, in other embodiments, the input may be to input a size parameter for the primitive's length control 332, width control 334, angle control 336.

In response to detecting an input to change the first size of the first primitive 320 in the layout drawing in the target space, at block 220, the terminal device 110 determines a changed second size. The first primitive 320 represents a target element in a target space and the first primitive includes a first number of sub-primitives. In some embodiments, the target element is a straight staircase and the sub-primitives represent rectangular ladders of the straight staircase, the first size comprising at least one of: the length, width and height of the straight ladder or the rectangular ladder.

In the example of fig. 3A to 3D, the length of the sub-primitive is 300 mm. In user interface 301 shown in FIG. 3B, terminal device 110 detects a drag gesture by user 102 with respect to widget 335, thereby determining that the width of first graphical element 320 changed from a first size of "1000 mm" to a second size of "2000 mm". As shown in fig. 3B, terminal device 110 may, in turn, scale first primitive 320 to a second primitive 322 having a second size as the gesture is dragged.

In some embodiments, the input to change the first size only changes the size of sub-primitives in the first primitive and does not change the first number of sub-primitives. For example, in the example of FIG. 3B, the first primitive 320 and the second primitive 322 have the same number of sub-primitives. The second graphical element 322 represents a wider vertical ladder in the target space than the first graphical element 320.

Additionally or alternatively, in other embodiments, an input that changes the first size will cause a change in the first number of driver primitives. Depending on the size of the second size, it may happen that the last sub-element does not have the full size. In this case, the last sub-image element needs to be rendered to full size. In user interface 302 shown in FIG. 3C, terminal device 110 detects a drag gesture by user 102 with respect to control 333, thereby determining that the length of first graphical element 324 changes from the first size "1200 mm" to the second size "2600 mm". In this case, the altered second size corresponds to a larger sub-primitive than the first size, but the last sub-primitive 325 is only 200mm in length. In practice, such sub-primitives need to be drawn as full sub-primitives of length 300 mm.

At block 230, terminal device 110 determines a second number of sub-primitives based on a second size.

In some embodiments, in response to the second size corresponding to a non-integer number of sub-primitives, terminal device 110 may determine a remainder based on the second size and the size of the sub-primitives. Terminal device 110 may then determine a second number based on the second size and the remainder. In particular, assume that the width of the straight ladder (e.g., corresponding to the width of the first primitive) is represented by W, the height (e.g., corresponding to the length of the first primitive) is represented by H, and the height of each ladder (e.g., corresponding to the length of each sub-primitive) is m. Terminal device 110 may determine the remainder, represented by R, based on equation (1) below:

R＝H％m (1)

then, the terminal device 110 may determine the number of complete sub-primitives corresponding to the vertical ladder height, which is represented by N, based on the following equation (2):

N＝(H-R)/m (2)

as previously mentioned, the second number of sub-primitives is determined to be N +1, since the remainder, i.e. R ≠ 0, occurs, and the last staircase should be represented by the complete sub-primitive.

In the example of fig. 3C, m is 300mm, H is 2600mm, so R is 200, N is 8, and accordingly the second number is determined to be 9.

At block 240, terminal device 110 determines a second set of reference points for at least a portion of the second number of sub-primitives based on the first set of reference points and the second number for the first number of sub-primitives.

In some embodiments, the first and second sets of reference points each comprise a vertex of at least one sub-primitive. For example, in case the target element is a straight ladder, the vertices of the sub-elements may be the vertices of a rectangular ladder. As another example, where the target element is a circle ladder, the vertices of the sub-elements may be the vertices of a fan ladder.

At block 250, terminal device 110 renders a second primitive in the layout map to replace the first primitive based on the second set of reference points.

In some embodiments, in response to the first number being less than the second number, terminal device 110 may connect the second set of reference points to render the second primitive based on the first predetermined order. FIG. 3D illustrates a second primitive 326 rendered based on input to the control 333 in FIG. 3C. In contrast to sub-primitive 325 in FIG. 3C, in user interface 303, the last sub-primitive 327 of the second primitive 326 is rendered as a complete sub-primitive having a length of 300 mm. Additionally or alternatively, as an example implementation, since the first number is less than the second number, the second set of reference points may be vertices of a second number of sub-primitives that are more sub-primitives than the first number of sub-primitives. Accordingly, terminal device 110 may connect the second set of reference points based on the first predetermined order to cycle through drawing rectangular sub-primitives (e.g., drawing rectangles with a vector graphics renderer) on the basis of the first number of sub-primitives until a second number of rectangular sub-primitives is obtained.

Additionally or alternatively, in other embodiments, in response to the first number being greater than the second number, terminal device 110 may determine a difference from the first number and the second number as the third number. Terminal device 110 may then render the second primitive by removing a third number of sub-primitives from the first primitive.

In some embodiments, terminal device 110 may smoothly display the second graphical element with the input. Additionally or alternatively, in other embodiments, terminal device 110 may display the second primitive after the size change reaches a certain length.

In some embodiments, the target element is a gyrotron and the sub-elements represent fanshaped steps of the gyrotron, the first dimension comprising at least one of: the length, width, height and convolution angle of the convolution ladder or the fan-shaped ladder. Fig. 4A-4D illustrate schematic diagrams of user interfaces for drawing primitives in which a representation clothoid primitive is presented and the clothoid primitive has a first number of sub-primitives representing fantasy steps of the clothoid, in accordance with some embodiments of the present disclosure.

As shown in fig. 4A, user interface 400 includes element controls 410 similar to user interfaces 300, 301, 302, and 303, controls 412 for manipulating the layout, and controls 441 through 443 in operation area 440. Therefore, the description thereof is omitted.

User interface 400 also includes an information area 430 for the target element in which the properties, size, and distortion parameters of the target element are presented, and includes type controls 431, size controls 433 and 435, and distortion controls 437 and 439. The type of primitive currently being rendered may be altered by activating type control 431. The length 432, width 434, angular range 436, etc. parameters of the primitive may be adjusted accordingly by activating controls 433, 435, and 437. In the example of FIG. 4A, controls 433, 435, and 437 are shown as slider controls, and user 102 changes the size of the size parameter or the distortion parameter by dragging the slider left or right. In addition, control 439 provides several sub-controls for predetermined angles. The user 102 may set the first primitive 420 to a corresponding predetermined angle by activating one of the child controls of the control 439. Additionally or alternatively, user 102 may enter respective parameters in length control 432, width control 434, angle range control 436, and angle control 438 to adjust the rendered primitives.

It should be understood that the types and numbers of properties, operations, and controls presented for different target elements may be different. Accordingly, the layout of the user interface 400 and the controls therein are merely illustrative and are not intended to limit the scope of the present disclosure in any way.

In the user interface 401 shown in FIG. 4B, the user 102 drags the control 433 to change the length of the first graphical element 420. The terminal device 110 detects the input of the changed length, and determines that the changed length is "3200 mm". In the example of fig. 4A and 4B, since the length parameter of the first graphical element corresponds to the diameter of the clothoid, the width parameter of the first graphical element also varies proportionally with the length parameter. As shown in FIG. 4B, in the user interface 401, the first graphical element 420 is scaled to a larger diameter second graphical element 422 with the drag gesture. In this case, the input of varying length only varies the size of the sub-primitives representing the fan staircase, and not the number of sub-primitives.

In the user interface 402 shown in FIG. 4C, the user 102 drags the control 437 to change the angular extent of the first graphical element 420. In an embodiment of the present disclosure, the angular range represents a convolution magnitude of the convolution ladder. The terminal device 110 detects the input of the changed angle range, and determines that the changed angle range is "80%", which corresponds to 288 degrees. Thus, in the example of FIG. 4C, an input that changes the angular range will cause a change in the first number of sub-primitives representing the fan-shaped staircase. Depending on the size of the angular range, it may happen that the last sub-element does not have the full size. In this case, the last sub-image element needs to be rendered to full size.

In the example of FIG. 4C, the altered angular range corresponds to a greater number of sub-primitives than the original angular range. However, in the example of FIGS. 4A-4D, the angular extent of the sub-primitives is 22.5 degrees, in which case the angular extent of the last sub-primitive 424 is only 18 degrees. In practice, such sub-primitives need to be rendered as full sub-primitives of length 22.5 degrees.

In some embodiments, terminal device 110 may determine an integer number of sub-primitives, i.e., a second number of sub-primitives, corresponding to the changed angular range based on equations (1) and (2). Terminal device 110 may then determine a second set of reference points for at least a portion of the second number of sub-primitives based on the first set of reference points and the second number of the first number of sub-primitives. As an example, the first and second sets of reference points may be represented by coordinates of four corner points of the sector sub-primitives representing the respective sector staircase.

In some embodiments, terminal device 110 can scale first graphical element 420 to a second graphical element of a larger angular range as a drag gesture applied by user 102 at control 437. Additionally, as an example implementation, in user interface 403 shown in FIG. 4D, terminal device 110 may render last sub-primitive 424 as complete sub-primitive 426 upon detecting that user 102 released the drag gesture applied to control 437.

In some embodiments, in the example of fig. 4D, terminal device 110 may connect the second set of reference points based on a second predetermined order to cycle through the drawing of the fan-shaped sub-primitives on the basis of the first number of sub-primitives (e.g., drawing the fan-shaped based on the angular range of the fan-shaped sub-primitives drawing straight lines and arcs) until a second number of fan-shaped sub-primitives is reached.

In some embodiments, terminal device 110 may smoothly display the second graphical element with the input. Additionally or alternatively, in other embodiments, terminal device 110 may display the second graphical element after the size change reaches a certain angle.

According to some embodiments of the present disclosure, a scheme for drawing primitives is provided. The method can parameterize the attribute and the size of the space element, so that the size, the angle and the shape of the graphic elements in the space layout can be flexibly adjusted by changing the parameters. The solution also provides a user interface for drawing primitives and supports adjusting primitives in a visualized interactive manner. Through the scheme, the manufacturing process of the layout can be simplified, and the labor cost is saved. In addition, the scheme can also guarantee the accuracy of the spatial layout and enhance the presentation effect of the layout.
