Hair processing method and system for game role

Abstract

The invention provides a hair processing method and system for a game role. The method comprises: a simulated light source is established, an own color of a hair model and light and dark information are drawn at a diffuse map, and a high-light map of the hair model is superposed with the simulated light source; a transparent part and a non-transparent part of the obtained hair model are rendered by using dual channels; and interspersed processing including mesh segmentation execution is carried out on the rendered hair model and dynamic rendering of the hair model is carried out. The hair processing method and system have the following beneficial effects: the hair expression effect becomes vivid with good layering effect; performance consumption caused by a real light source can be reduced and a specific light source effect can be processed, so that the high light expression becomes vivid in detail; because of semi-transparent mixing, high-efficiency processing of rendering and interspersed processing is realized; and the interspersed problem caused by semi-transparent mixing can be solved and real-time triangular sorting can be avoided, and a hair rendering interspersing problem can be solved efficiently.

Description

technical field [0001] The invention relates to a hair treatment method and system for game characters, belonging to the field of computers. Background technique [0002] With the improvement of game quality requirements, the realistic rendering effect of character hair will be able to highlight the real hair effect of the character model, making the character rendering more vivid and lifelike. Generally, games use the simplest diffuse reflection map plus specular map processing technology to process the hair of characters. [0003] The basic flow chart of the technology of using diffuse reflection plus highlight channel is as follows, please refer to figure 1 : [0004] The diffuse channel uses the dot product of the incident ray and the normal to calculate the diffuse color, and the specular channel uses the dot product of the half-angle vector (the median of the incident ray and line of sight) and the normal to calculate the specular highlight of the object.

Problems solved by technology

[0007] (2) Due to performance considerations in mobile games, real-time light is often not added but lightmaps are baked. This method makes hair unable to show the light and shadow effects under real lighting, making hair rendering unsatisfactory. how real

Even if the real-time pixel light is added, in most cases the light source is used to illuminate the scene objects, and the light source is set as a fixed light source. In this way, the light source with a fixed direction reflects the hair and the highlight effect rendered may not be what we want. to see

[0008] (3) The hair tends to be mostly opaque and a little transparent. The end of the hair should be processed in a translucent and mixed way to achieve a more realistic and realistic effect. However, the old solution did not do any processing on this layer
