Abstract

The invention discloses a processing method and device of ambient occlusion (AO). The method includes: respectively selecting a corresponding reference vertex for each vertex on a target mesh object in a vertex set of a source mesh object; acquiring values of three-dimensional spatial distances between the reference vertices and the corresponding vertices on the target mesh object, and normalizingthe values of three-dimensional spatial distances to obtain vertex occlusion values; and storing the vertex occlusion values into data channels of the corresponding vertices on the target mesh object. The method solves technical problems that self-shadowing effects obtained by ambient occlusion calculation manners provided in the related art are poorer and require higher calculation overheads.

Description

technical field [0001] The present invention relates to the field of three-dimensional image rendering, in particular to a processing method and device for ambient light shading. Background technique [0002] At present, the real-time rendering of the leaf grid adopted in the related art is usually formed by intersecting the surfaces of multiple two-dimensional geometric bodies with leaf cluster textures. figure 1 is a schematic diagram of an application example of a cross plane method according to the related art. Such as figure 1 As shown in , 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 plane. The ingenious combination ena...
