For example, in response to receiving an active request from the user, prompt information is sent to the user to explicitly prompt the user that the requested operation will require the acquisition and use of the user's personal information. Therefore, the user can independently choose whether to provide personal information to software or hardware such as electronic devices, applications, servers, or storage media that perform operations of the technical solutions of the present disclosure according to the prompt information.

An exemplary application scenario for a floor plan is a house plan, where elements can include walls, doors, windows, stairs, and so on. The house floor plan is used to reflect information such as house area, floor plan, wall distribution, room orientation, functional zoning, and floor lighting. Usually, when drawing a house plan, it is necessary to refer to the images taken on the house site and the measured data. However, when drawing some elements in the floor plan, the corresponding primitives cannot be generated by the computer, but the primitives are adjusted by scaling the picture in equal proportions.

For example, when drawing a vertical ladder, you can only adjust the size of the ladder by scaling the image proportionally. This method cannot dynamically adjust the steps and widths of the steps according to the housing conditions. Also, when stretching the picture, it may cause picture distortion. In addition to house floor plans, other scenarios for drawing spatial layouts also face similar problems. Therefore, it is expected to improve the production process of the space layout diagram so as to be able to flexibly adjust various primitives in the space layout diagram.

Embodiments of the present disclosure propose solutions for drawing primitives. This solution can parameterize the attributes of space elements, so that the size and shape of primitives in the space layout diagram can be adjusted accurately according to the parameters. In addition, the scheme provides a user interface for drawing primitives, and supports adjusting primitives in a flexible and interactive manner. In this way, the production efficiency of the spatial layout diagram can be improved, the accuracy of the spatial layout diagram can be ensured, and the presentation effect can be enhanced.

Hereinafter, embodiments of the present disclosure will be described in conjunction with the scenario of a house floor plan. However, it should be understood that the house floor plan is only one of many application scenarios of the embodiments of the present disclosure, and the embodiments of the present disclosure are also applicable to other scenarios, such as engineering construction, urban planning, traffic management, and so on. Therefore, the scope of the embodiments of the present disclosure is not limited thereto.

Furthermore, embodiments are also 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 there may actually be various interface designs and interaction modes. Additionally, the controls included in these UIs may be implemented using any currently known or future developed UI elements and techniques. Furthermore, the type, form, operation mode, layout, arrangement, etc. of these controls in the UI are all illustrative, and are not intended to limit the scope of the present disclosure in any way.

FIG. 1 shows a schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented. In the example environment 100, the end device 110 may be used to make a floor plan for the target space. In some embodiments, the target space may be a house, a building, or the like. Correspondingly, the floor plan may be a house plan, a building 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 present disclosure are not limited in this regard.

In some embodiments, the real-life pictures and modeling images used for making the floor plan may be photographed or generated by the user through the terminal device 110 . In other embodiments, these live-action pictures or modeled images may come from any other data source. Furthermore, in some embodiments, the 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 to the user 102 a user interface for the user to make a floor plan, as described in detail below in conjunction with FIGS. 2 , 3A-3D, and 4A-4D.

Terminal device 110 may be any type of mobile terminal, stationary terminal or portable terminal, including mobile phone, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, media computer, multimedia tablet, personal communication system (PCS) devices, personal navigation devices, personal digital assistants (PDAs), audio/video players, digital cameras/camcorders, pointing devices, television receivers, radio receivers, e-book devices, gaming devices, or any combination of the foregoing, Includes accessories and peripherals for these devices or any combination thereof. In some embodiments, end devices 110 and 120 are also capable of supporting 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, update and access to floor plan data of the target space. For example, remote devices may be used to expand the storage and processing capabilities of end device 110 . In some embodiments, the remote devices may be various types of computing systems/servers capable of providing computing capabilities, including but not limited to mainframes, edge computing nodes, electronic devices in cloud environments, and the like.

In this context, pictures, measurement data, and floor plans of the target space may have any data format. Embodiments of the present disclosure are not limited in this regard. It should also be understood that the structure and functionality of environment 100 are described for exemplary purposes only and do not imply any limitation on the scope of the present disclosure.

Reference will now be made to FIG. 2, which shows a flowchart 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 also be implemented at any suitable device. For ease of discussion, process 200 will be described with reference to 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 mentioned above, the target space can be a real space or a virtual space, and it has elements that can reflect the structural layout, area of the space, the position, orientation, area, use function and other attributes of each subspace, including but not limited to stairs, Doors, windows, walls, etc. These elements can be represented by corresponding primitives in the floor plan, and the scale of the primitives in the floor plan is basically the same as the scale of the elements in the target space.

In the process 200, the terminal device 110 adjusts the primitives in the layout. As an example, the user 102 may adjust the size, angle, shape, etc. of various primitives in the layout through the user interface of the application 120 presented in the terminal device 110 .

FIGS. 3A-3D illustrate schematic diagrams of a user interface for drawing primitives, wherein the ladder primitives are presented, and the ladder primitives have a first number of sub-primitives, according to some embodiments of the present disclosure, The sub-entity represents the rectangular ladder of a straight ladder. As shown in FIG. 3A, the user interface 300 includes an element control 310, and the user 102 can activate the sub-controls representing the corresponding elements in the element control 310 through gestures such as clicking, dragging, etc., to add primitives to the layout. In the example of FIG. 3A, a first primitive 320 is added to the layout by activating a sub-control representing a vertical ladder.

The user interface 300 also includes controls 312 for manipulating the layout map, and corresponding operations on the layout map can be triggered by activating corresponding sub-controls in the controls 312 . It should be understood that the sub-controls in control 312 are merely exemplary. In practice, sub-controls different from those in the user interface 300 may be provided as required, which will not be described in detail in this disclosure.

User interface 300 also includes an information area 330 and an operation area 340 for the target element. Information area 330 presents properties and size parameters of the target element, and includes type control 331 and size controls 333 , 335 , 337 and 338 . The currently drawn primitive type can be changed by activating the type control 331 . By activating controls 333, 335, 337, and 338, size parameters such as length 332, width 334, and angle 336 of the primitive can be adjusted accordingly. In the example of FIG. 3A, controls 333, 335, and 337 are shown as slider controls, and the user 102 changes the size of the corresponding size parameter by dragging the slider left or right. Additionally, control 338 provides several sub-controls for predetermined angles. The user 102 may set the first primitive 320 to a corresponding predetermined angle by activating one of the sub-controls of the control 338 . The operation area 340 includes controls 341 to 343 for performing operations such as left-right mirroring, inside-outside mirroring, deleting elements, and the like for the first graphic element.

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

At block 210, the terminal device 110 detects an input that changes the first size of the first primitive in the layout map of the target space. In some embodiments, the input may be a touch gesture with respect to the screen of the 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 a length control 332, width control 334, angle control 336 input size parameters for primitives.

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

In the example of FIGS. 3A to 3D , the length of the sub-element is 300 mm. In the user interface 301 shown in FIG. 3B , the terminal device 110 detects the drag gesture of the user 102 on the control 335, thereby determining that the width of the first graphic element 320 is changed from the first size “1000mm” to the second size “2000mm” ". As shown in FIG. 3B , the terminal device 110 can further scale the first graphic element 320 into a second graphic element 322 having a second size with the drag gesture.

In some embodiments, the input that changes the first size only changes the size of the 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. Compared to the first primitive 320, the second primitive 322 represents a wider straight ladder in the target space.

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

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

In some embodiments, in response to the second size corresponding to a non-integer number of sub-picture elements, terminal device 110 may determine the remainder based on the second size and the size of the sub-picture elements. Then, the terminal device 110 may determine the second number based on the second size and the remainder. Specifically, assuming that the width of the vertical ladder (eg, the width corresponding to the first primitive) is denoted by W, the height (eg, the length corresponding to the first primitive) is denoted by H, the height of each step (eg, corresponding to the length of each sub-primitive) is m. The terminal device 110 can determine the remainder based on the following formula (1), which is represented by R:

R=H%m (1)

Then, the terminal device 110 can determine the number of complete sub-picture elements corresponding to the height of the vertical ladder based on the following formula (2), which is represented by N:

N=(H-R)/m (2)

As mentioned earlier, since the remainder occurs, ie R≠0, the last step should be represented by a complete sub-picture element, therefore, the second number of sub-picture elements is determined as N+1.

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

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

In some embodiments, the first set of reference points and the second set of reference points each include vertices of at least one sub-primitive. For example, in the case where the target element is a straight ladder, the vertex of the sub-primitive can be the vertex of a rectangular ladder. As another example, in the case where the target element is a roundabout, the vertices of the sub-primitives may be vertices of a fan-shaped staircase.

At block 250, the terminal device 110 renders the 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, the terminal device 110 may connect the second set of reference points based on the first predetermined order to present the second primitive. Figure 3D shows a second primitive 326 rendered based on input to control 333 in Figure 3C. Compared to the sub-primitive 325 in FIG. 3C, in the user interface 303, the last sub-primitive 327 of the second primitive 326 is presented as a complete sub-primitive with 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 of more sub-picture elements of the second number of sub-picture elements than the first number of sub-picture elements. vertex. Accordingly, the terminal device 110 may connect the second set of reference points based on the first predetermined order to cyclically draw rectangular sub-primitives (eg, using a vector graphics renderer) on the basis of the first number of sub-primitives, until obtaining The second number of rectangular sub-primitives.

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

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

In some embodiments, the target element is a roundabout, and the sub-primitive represents a fan-shaped staircase of the roundabout, and the first size includes at least one of the following: length, width, height, and rounding angle of the roundabout or the fan-shaped staircase. FIGS. 4A-4D illustrate schematic diagrams of a user interface for drawing primitives, in which a representation of the roundabout primitive is presented and the roundabout primitive has a first number of sub-primitives, according to some embodiments of the present disclosure, The sub-entity represents the fan-shaped steps of the roundabout.

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 map, and controls 441 to 443 in operation area 440 . Therefore, no detailed description is given here.

The user interface 400 also includes an information area 430 for the target element, in which the properties, dimensions, and deformation parameters of the target element are presented, and includes a type control 431 , size controls 433 and 435 , and deformation controls 437 and 439 . The currently drawn primitive type can be changed by activating the type control 431 . By activating controls 433, 435 and 437, parameters such as length 432, width 434, angle range 436, etc. of the primitive can be adjusted accordingly. In the example of FIG. 4A, controls 433, 435, and 437 are shown as slider controls, and the user 102 changes the size of the size parameter or deformation parameter by dragging the slider to the left or right. Additionally, 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 sub-controls of the control 439 . Additionally or alternatively, user 102 may enter corresponding 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 type and number of properties, operations and controls presented for different target elements may be different. Accordingly, the layout of 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 primitive 420 . The terminal device 110 detects the input of changing the length, and determines that the changed length is "3200 mm". In the example of FIG. 4A and FIG. 4B , since the length parameter of the first primitive corresponds to the diameter of the roundabout, the width parameter of the first primitive also changes proportionally with the length parameter. As shown in FIG. 4B , in the user interface 401 , the first primitive 420 is scaled into a second primitive 422 with a larger diameter along with the drag gesture. In this case, changing the length of the input only changes the size of the sub-primitives representing the fan-shaped ladder, 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 range of the first primitive 420 . In an embodiment of the present disclosure, the angle range represents the swing amplitude of the swing ladder. The terminal device 110 detects the input of changing the angle range, and determines that the changed angle range is "80%", which corresponds to 288 degrees. Thus, in the example of Figure 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 extent, it may happen that the last sub-entity does not have the full size. In this case, the last sub-primitive needs to be drawn to full size.

In the example of Figure 4C, the changed 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 range of the sub-primitives is 22.5 degrees, and in this case, the angular range of the last sub-primitive 424 is only 18 degrees. In practice, such sub-primitives need to be drawn as full sub-primitives with a length of 22.5 degrees.

In some embodiments, the terminal device 110 may determine, based on formulas (1) and (2), an integer number of sub-picture elements corresponding to the changed angle range, that is, the second number of sub-picture elements. The terminal device 110 may then determine a second set of reference points for at least a portion of the second number of sub-picture elements based on the first group of reference points and the second number of the first number of sub-picture elements. As an example, the first set of reference points and the second set of reference points may be represented by coordinates representing the four corner points of the fan-shaped sub-primitives of the respective fan-shaped steps.

In some embodiments, the terminal device 110 may scale the first graphic element 420 into a second graphic element with a larger angular range in response to the drag gesture applied by the user 102 on the control 437 . Additionally, as an example implementation, in the user interface 403 shown in FIG. 4D , the terminal device 110 may present the last sub-element 424 as complete after detecting that the user 102 releases the drag gesture applied to the control 437 sub-primitive 426.

In some embodiments, in the example of FIG. 4D, terminal device 110 may connect a second set of reference points based on a second predetermined order to cyclically draw fan-shaped sub-primitives based on the first number of sub-primitives (eg, based on The angle range of the fan-shaped sub-primitives is drawn by drawing straight lines and arcs) until the second number of fan-shaped sub-primitives is obtained.

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

According to some embodiments of the present disclosure, a scheme for drawing primitives is provided. The scheme can parameterize the attributes and dimensions of space elements, so that the size, angle and shape of primitives in the space layout diagram can be flexibly adjusted by changing the parameters. The solution also provides a user interface for drawing primitives and supports adjusting primitives in a visual and interactive way. Through this solution, the production process of the layout diagram can be simplified and labor costs can be saved. In addition, this solution can also ensure the accuracy of the spatial layout and enhance the presentation effect of the layout.
