Abstract

The present invention provides a vertex normal processing method and apparatus. According to the method provided by the present invention, a source mesh object that is adapted to a to-be-rendered target mesh object is created; in the vertex set of the source mesh object, a corresponding reference vertex is selected for each vertex of the target mesh object; and the normal of the selected reference vertex is mapped to the corresponding vertex of the target mesh object, so that the problem of the relatively poor light rendering effect obtained by using the vertex normal setting manner on the target mesh object in the related art is solved, and the overall light rendering effect with the volumetric feeling of the to-be-rendered target mesh object in the three-dimensional space can be achieved.

Description

technical field [0001] The present invention relates to the field of three-dimensional image rendering, in particular to a method and device for processing vertex normals. Background technique [0002] At present, the real-time rendered leaf grids used in the related art are usually formed by crossing planes with cluster leaf textures. The intersecting plane method used here is to use multiple intersecting planes to express an object together. figure 1 is a schematic diagram of an application example of the cross plane method according to the related art. Such as figure 1 As shown, due to the existence of intersecting planes, the user can observe the plane with the leaf texture from different angles. The key to this processing method is to select different cross planes for different 3D objects (such as trees, flowers, hair) that can be represented by the cross plane method in the current running game environment, and the texture can also be realized with the corresponding...
