Relaxed Sorting in a Position-Only Pipeline

摘要

In the cull pipe, positions of the vertices of a triangle have already been computed and these coordinates may be exploited by taking and sorting triangle groups based on these coordinates. As one example, all the triangles in a tile may constitute a group. The triangle groups are sorted into bins. Within each bin the triangles are sorted based on their depths.
