Graphics rendering pre-processing method and system

Abstract

The invention relates to a graphics rendering pre-processing method and a graphics rendering system. The method comprises the following steps of: 1, drawing a normal map of a model object; 2, drawinga fixed environment reflection simulation map of the scene; 3, establishing lighting environment information and UV texture information of the model object, and conducting baking according to the lighting information and the UV texture information to obtain a lighting map; 4, drawing a diffuse reflection map of a model object, comprising four channel of R, G, B and A; 5, incorporating Fresnel information and glossiness information into that diffuse reflection map to form final diffuse reflection sampling data; 6, according to the final diffuse reflection sampling data and the normal map in step 1, generating a material ball, and outputting the material ball and the illumination map as the rendering resources of the client. The normal line details and the texture and shadow effect are maintained, and at the same time, through the optimization of the algorithm and the logic, the overall resource occupancy of the client is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of rendering processing, and more specifically, to a preprocessing method and system for graphics rendering. Background technique [0002] For the preprocessing of the scene graphics rendering of the existing 3D next-generation mobile games, the conventional method is to render on the client side based on real-time lighting, and render through three texture samples: Diffuse (diffuse), Specular (highlight), and Normal (normal). It is used to restore the real model details, light and shadow, and material texture performance. The purpose of client-side real-time rendering is to show realistic effects as much as possible. [0003] Normal details, high-gloss texture, and high-light-based environmental reflection effects are important features of the pre-processing of next-generation graphics rendering, and the picture effect is far superior to that of traditional scene baking. On the other hand, the cu...

Problems solved by technology

[0020] The above solution leaves a large amount of computing work for real-time rendering (real-time calculation of light and shadow changes) to the client. Although it can present the details, texture, and light and shadow effects in the real world, the requirements for the client's performance are too high, which is not conducive to Guaranteed customer experience
