Description

Technical Field

[0001] The present invention belongs to the technical field of wall design, and in particular relates to a method, a device, an electronic device and a storage medium for realizing the closure of positive and negative corners. Background Art

[0002] At present, the finished surface design based on the wall only performs a simple finished surface elevation design, and the finished surface at the corners cannot be formed. The specific existing data structure roughly needs to include point, edge, and area information, and the area contains the elevation of the area. The data structure expresses the geometric data and elevation of the area, based on which three-dimensional modeling is performed to generate a surface, and then based on the surface, the corresponding paving is generated. From the modeling method, it can be seen that the user realizes the finished surface through the plane modeling tool. Since each plane modeling tool is an independent protrusion modeling, it has no connection with the plane modeling on the other side, so there will be a technical problem of missing the corners.

[0003] The existing method of generating Yin-Yang angles is based on modifying the topological structure to generate new edges and faces. For example, the patent application with publication number CN117708944A discloses a method, device, electronic device and storage medium for generating Yin-Yang angles. The specific implementation scheme is: determine the Yin-Yang angle area to be processed in the apartment data; select the target line style from the pre-configured multiple Yin-Yang angle line styles; wherein each of the multiple Yin-Yang angle line styles includes the line profile and the position information of the line reference point, and the line profiles in different Yin-Yang angle line styles are different; based on the position information of the line reference point in the target line style, determine the apartment data reference point that matches the line reference point in the Yin-Yang angle area; based on the apartment data reference point, add the Yin-Yang angle lines with the same line profile as the target line style in the Yin-Yang angle area. This method generally requires additional support for the generation of corner lines or light strips attached to new edges and faces, and paving. It is also necessary to consider more boundary conditions and whether special processing is required. Summary of the invention

[0004] In view of the above, an object of the present invention is to provide a method, device, electronic device and storage medium for achieving the closure of the Yin-Yang angle, so as to achieve the generation and closure of the Yin-Yang angle.

[0005] To achieve the above-mentioned purpose of the invention, an embodiment provides a method for closing a yin-yang angle, comprising the following steps:

[0006] Calculate the data structure of each side of the plane shape at the corner according to the plane shape height on both sides of the corner and the angle of the corner, the data structure includes the elevation height, horizontal offset, and area ID of the point on the plane shape;

[0007] According to the data structure, the plane shape on each side is obliquely modeled to generate an extended body, which will form the Yin-Yang corners of the plane shape and realize the closure of the Yin-Yang corners.

[0008] In one embodiment, the method further includes: where a Yin-Yang corner needs to be generated, checking whether the plane shapes on both sides of the Yin-Yang corner meet the Yin-Yang corner conditions, that is, judging whether the vertical division of the shape area is consistent, and if the vertical division is consistent, it is considered that the Yin-Yang corner can be generated.

[0009] In one embodiment, the method also includes: when the plane shape on each side is obliquely modeled according to the data structure, the angle line on the plane shape will be naturally extended, and the bound curves of the respective angle lines of the extension bodies on the left and right sides of the Yin-Yang angle are specifically identified as the lofting path, and the two lofting paths on both sides are regarded as a whole lofting path. Based on this whole lofting path, the angle line with the closing effect of the Yin-Yang angle is generated by lofting.

[0010] In one embodiment, the method also includes: when the plane shape on each side is obliquely modeled according to the data structure, the light strip on the plane shape will be naturally extended, and the bound curves of the respective light strips of the extension bodies on the left and right sides of the Yin-Yang corner are specifically identified as the lofting path, and the two lofting paths on both sides are regarded as a whole lofting path. Based on this whole lofting path, a light strip with a closed Yin-Yang corner effect is lofted and generated.

[0011] To achieve the above-mentioned purpose of the invention, the embodiment further provides a device for closing the internal and external corners, comprising:

[0012] A data generation module is used to calculate the data structure of each side of the plane shape at the corner according to the plane shape height on both sides of the corner and the angle of the corner, and the data structure includes the elevation height, horizontal offset, and area ID of the point on the plane shape;

[0013] The module for generating closed Yin-Yang corners is used to perform oblique modeling on each side of the plane shape according to the data structure to generate an extension body, which will form the Yin-Yang corners of the plane shape and realize the closure of the Yin-Yang corners.

This oblique modeling method does not change the topological structure, but only changes the position and length of the points, edges, and faces. This will make a series of subsequent related supports such as paving, corner lines, and light strips naturally supported or relatively easy to implement. Furthermore, the judgment of boundary conditions will increase the complexity of program calculations. The present invention does not need to consider too many boundary conditions, thereby reducing computing consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0026] like Figure 2 As shown in the figure, the data structure expressing the protrusion in the existing wall design generally includes point, edge, and region information. The region includes the elevation of the region. The data structure expresses the geometric data and elevation of the region, based on which three-dimensional modeling is performed to generate a surface. Then, based on the surface, the corresponding paving is generated. Figure 3 As shown in the figure, from the modeling method, when users use plane modeling tools to complete the surface, the problem of missing yin and yang corners will occur. This is because each plane modeling tool is an independent protrusion modeling, and has no connection with the plane modeling on the other side.

[0027] To solve this technical problem, the embodiment of the present invention provides a method for achieving closed yin and yang angles, the core idea of ​​which is to change the way of modeling the protrusions of the plane modeling from simple vertical protrusions to allowing oblique protrusions to be modeled, such as Figure 4 As shown in the figure, the modeling of the middle point of the area is still the raised protrusion modeling, and only the protrusion modeling method of the edge point is changed to oblique modeling. This can directly form a closed Yin-Yang corner after modeling.

[0028] Based on the above core ideas, such as Figure 1 As shown, a method for achieving closure of yin-yang angles provided in an embodiment includes the following steps:

[0029] S1, calculating the data structure of each side of the plane shape at the corner according to the plane shape height on both sides of the corner and the angle of the corner, the data structure includes the elevation height, horizontal offset, and area ID of the point on the plane shape.

[0030] Based on the oblique protrusion modeling proposed by the present invention, firstly, when obtaining the corresponding point after protrusion stretching, in addition to the elevation distance from the region, a certain horizontal offset is also required for a point on the plane modeling. Secondly, a point on the plane modeling can have multiple points after protrusion stretching, and these points can belong to different regions, such as Figure 3 As shown, Figure 3 After the A0 point is stretched, two corresponding points A1 and A2 can be obtained, which belong to two regions. Therefore, a region ID needs to be added to accurately express the results of all corresponding points after the original point protrusion is stretched. Therefore, when modeling oblique protrusions, the required data structure is newly defined to include the elevation height, horizontal offset, and region ID of the point on the plane model. Based on this data structure, it is clear how to perform oblique modeling in the future.

[0031] In the embodiment, the calculation of generating the Yin-Yang angle is triggered by user interaction. After that, the adjacent plane shapes that constitute the Yin-Yang angle of the entire scheme are traversed in sequence. Where the Yin-Yang angle needs to be generated, the plane shapes on both sides of the Yin-Yang angle are checked to see if they meet the conditions of the Yin-Yang angle, that is, whether the vertical division of the shape area is consistent. If the vertical division is consistent, it is considered that the Yin-Yang angle can be generated, and the regional contours of the plane shapes on both sides of the Yin-Yang angle are checked. If the distribution of these regional contours in the vertical direction is consistent, so that the areas on both sides of the Yin-Yang angle can correspond one to one, then it is considered that the Yin-Yang angle can be generated.

[0032] Specifically, the need to generate a Yin-Yang corner is triggered by user interaction. Then, when the Yin-Yang corner needs to be generated, the horizontal offset of each side of the plane shape at the Yin-Yang corner and the area ID to which it belongs are calculated according to the plane shape height on both sides of the Yin-Yang corner and the angle of the Yin-Yang corner, and a new data structure is formed with the elevation height of the point on the plane shape.

[0033] S2, based on the data structure, the plane shape on each side is obliquely modeled to generate an extension body, and the extension body will form the Yin and Yang corners of the plane shape and realize the closure of the Yin and Yang corners.

[0034] In the embodiment, the plane modeling on each side is obliquely modeled according to the data structure to generate an extension body to form the Yin-Yang corners of the plane modeling and achieve the closure of the Yin-Yang corners. This modeling method does not change the topological structure. Therefore, the subsequent support of the attached corner lines, light strips, paving, etc. is relatively easy to achieve.

[0035] For the corner lines of Yin-Yang angles, the corner lines are bound to the curves after modeling. Because the topological structure of the curve itself does not change during modeling and stretching, only the length changes, so the corner lines can naturally reach the required Yin-Yang angle length, that is, the curve generated by the new modeling method. However, simply increasing the length is not enough. The Yin-Yang angles of the corner lines also need to be processed to generate the shape of the Yin-Yang angles.

[0036] Specifically, during oblique modeling, the angle lines on the plane shape will naturally extend. The bound curves of the respective angle lines of the extended bodies on the left and right sides of the Yin-Yang angle are specifically identified as the lofting path. The two lofting paths on both sides are regarded as a whole lofting path. Based on this whole lofting path, the angle lines with the closing effect of the Yin-Yang angle are generated by lofting.

[0037] For the light strips at the yin and yang corners, a retracted light strip is placed on the plane modeling. Without considering the yin and yang corners, the retracted light strip will cause the plane modeling surface modeling to change and the modeling generation of the light strip. When considering the yin and yang corners, the curves after the yin and yang corners modeling can be directly used to construct the light strip. For example, if the curve of the yang corner is longer than the original curve, but the topology remains unchanged, the plane modeling changes and light strip modeling caused by the retracted original light strip can still be used based on the wireless after the length change.

[0038] Specifically, when the plane shape on each side is modeled obliquely according to the data structure, the light strip on the plane shape will be naturally extended, and the bound curves of the light strips of the extended bodies on the left and right sides of the Yin-Yang corner are specifically identified as the lofting path, and the two lofting paths on both sides are regarded as a whole lofting path. Based on this whole lofting path, the light strip with the closed effect of the Yin-Yang corner is generated by lofting.

[0039] In the above method, based on the new data structure through oblique modeling and the corresponding oblique modeling method, the topological relationship of the modeling result remains unchanged. That is, there is no deletion or addition of geometric elements such as points, edges, and regions, and the mutual relationship has not changed. Only the length of the edge and the area of ​​the region have changed. These changes will not greatly affect the corner lines, light strips, paving, etc., making these contents relatively easy to handle.

[0040] like Figure 5 As shown, the embodiment also provides a device 50 for achieving closed Yin-Yang corners, including: a data generation module 51 and a Yin-Yang corner closed generation module 52, wherein the data generation module 51 is used to calculate the data structure of the plane modeling on each side at the Yin-Yang corners according to the plane modeling heights on both sides of the Yin-Yang corners and the angles of the Yin-Yang corners, and the data structure includes the elevation height, horizontal offset, and area ID of the points on the plane modeling; the Yin-Yang corner closed generation module 52 is used to perform oblique modeling on each side of the plane modeling according to the data structure to generate an extension body, and the extension body will form a Yin-Yang corner of the plane modeling and achieve closed Yin-Yang corners.
