3D model render method and device

Abstract

The invention relates to a three-dimensional model rendering method and a device. The three-dimensional model rendering method comprises the following steps: acquiring three-dimensional model data andmaterial data, wherein the three-dimensional model data are used for describing the three-dimensional model created for the three-dimensional scene, the material data comprises a spherical map and amask map; simulating the texture effect of the three-dimensional model described by the three-dimensional model data through the spherical texture map; controlling a mask map according to the three-dimensional model data to occlude the texture effect simulated by the three-dimensional model; rendering and shading the 3D model that completes the simulation of the effect. The three-dimensional modelrendering method and device provided by the invention can improve the rendering efficiency of the three-dimensional model and further greatly improve the rendering performance.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a three-dimensional model rendering method and device. Background technique [0002] With the development of computer graphics technology, more and more 3D models can be displayed to users in 3D scenes. [0003] At present, the 3D model rendering process includes: first create a 3D model, and then use a shader (shader) to create a texture map with a certain material effect, so as to draw the texture map with a certain material effect on the 3D model for texture effect simulation, and finally complete the effect. The simulated 3D model is rendered and colored, and displayed in the 3D scene, so that the 3D model displayed in the 3D scene has a corresponding style. [0004] As users have higher and higher requirements for the style of 3D models in 3D scenes, for example, the style can be realistic, cartoon, hand-painted, etc., which often makes developers need to develop ...

AI Technical Summary

Problems solved by technology

[0004]Because users have higher and higher requirements for the style of 3D models in 3D scenes, for example, styles can be realistic, cartoon, hand-painted, etc. It often makes developers need to develop a variety of different shaders to make textures with different material effects, which is not only not conducive to maintenance, but also leads to high development costs, and may cause large performance consumption of user equipment
