Abstract
The invention discloses A screen tile-pair based binocular rendering pipeline process and method, comprising: completing space division according to a spatial relationship of two visual angles in stereo rendering, and generating input primitive lists corresponding to the divided space; searching non-full primitive lists of space divisions and obtaining a surface with spatial partition; and dispatching all generated spatial divisions, and simultaneously performing rasterizing and rendering of two visual angles for primitives in each space division. According to the new measures, a spatial correlation of two visual angles in stereo rendering is considered, and in a rendering process the two visual angles are rasterized and rendered at the same time, thereby reducing a bandwidth required for repeated reading of triangular data in the rendering process.
