Abstract

The invention provides a different-color display method and device for an overlapping area, and relates to the technical field of graphic processing. The method comprises the steps of determining a preset material for rendering an object model generated through modeling, wherein a rendering code block sequence is configured in the preset material, each pixel point in an area where the object model is located is correspondingly provided with a buffer value, the buffer values are used for representing the rendering times of the pixel points, corresponding code block execution conditions and material parameters are preset in each rendering code block, and a preset operation strategy for the buffer value is further arranged in the first rendering code block; in the process of rendering the object model according to the preset material, executing the rendering code block sequence in sequence for each pixel point in the area where the object model is located; and after the rendering code block sequence is executed, realizing material coverage rendering for the overlapping region, and realizing normal rendering for the non-overlapping region once, so that different-color display of the overlapping region is finally realized.

Description

technical field [0001] The present application relates to the technical field of graphics processing, and in particular, to a method and device for displaying different colors in overlapping regions. Background technique [0002] At present, in industrial projects and some 3D modeling software, in order to realize the different color display of overlapping parts, Boolean operations or methods similar to Boolean operations are generally used, through a series of complex methods such as digging holes, digging surfaces, modeling, and replacing materials. to achieve the effect. However, in actual projects, this method of simulating Boolean operations is inefficient, and will bring a certain amount of pressure on memory and CPU operations. Under normal circumstances, assuming that two simple patches are used for Boolean operations, 2-4 points are needed for traversal operations. However, when a large number of patches are displayed with overlapping colors, this is undoubtedly a ...
