Description

Technical Field

[0001] The present invention relates to the technical field of home decoration design, and in particular to a method and a display device for displaying a protruding shape of a background wall on a 2D plane. Background Art

[0002] Existing home decoration designs involve relatively more complex background wall designs, in which a large number of flat-shaped protrusions and protruding shapes such as light troughs are produced.

As a result, during the design process, users cannot obtain the relative position and other relationships between the design elements and the background wall shape. This can easily cause the model mold and the protruding shape to overlap and overlap, causing them to affect each other, thereby reducing the user's design experience and design efficiency.

[0122] In order to enable those skilled in the art to more clearly understand the technical solutions described in the embodiments of the present invention, the technical solutions described in the embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0123] Step 1: Get all plane shapes and light troughs, and filter out the plane shapes and light troughs on the ceiling and the ground based on the binding surface, which are the plane shapes and light troughs on the background wall.

[0124] Step 2: For each plane shape, obtain all areas of the shape and determine whether there are any raised areas. If so, obtain all the shape lines and light trough surfaces of the plane shape. Obtain all the shape surfaces and filter out the plane shape surfaces perpendicular to the ground plane. If not, skip the plane shape.

[0125] Step 3: For each light trough, find the styling line to which the trough is bound from all styling lines. Group all trough faces based on the IDs of the bound styling lines and trough faces. Filter trough faces based on the bound styling line type. The following rules apply: if the bound line is a straight line, select all faces that are not perpendicular to the ground plane; if the bound line is an arc, select all cylindrical faces. This step yields a grouping relationship between bound styling lines and trough faces.

[0126] Step 4: For each protruding area, obtain its area edge line, and find all the modeling surface and light trough surface data corresponding to the area edge line of the area from the modeling surface data and modeling line-light trough surface grouping data obtained in steps 2 and 3 according to the ID rule, to form the grouping data of area-modeling surface-light trough surface, that is, the projection grouping data of the modeling surface and light trough surface to be projected in units of area.

[0127] Step 5: Calculate the projection points for the modeling surfaces and light trough surfaces in each set of projection data. The calculation method is as follows: for planar modeling surfaces and light trough surfaces, directly obtain their boundary points (contourPoints), and then use matrix transformation to obtain the 2D coordinates of these boundary points on the ground plane, which are the projection points; for cylindrical modeling surfaces and light trough surfaces, first filter out the light trough surfaces that are determined to be side surfaces according to the ID rule, and then use matrix transformation and three-dimensional bounding box to calculate the projection boundary points in the three-dimensional coordinate system based on the boundary points (contourPoints) of the cylindrical surface and the coordinate system (ccs) of the modeling-bounded wall to which it is located. Finally, use matrix transformation to obtain the 2D coordinates of the projection boundary points on the ground plane, which are the projection points. This step obtains the projection point data for each set of modeling surfaces and light trough surfaces.

[0128] Step 6: For each set of projection point data, connect them and draw polygons, and add white default fill, which is the display of the protruding shape on the background wall in the 2D plane view.

[0129] Furthermore, the display effect of the protruding shape on the background wall in a 2D environment refers to Figure 2 As shown, after executing the method described in the embodiment of the present invention, the display effect of the protruding shape on the background wall in the 3D environment is shown in FIG.
