This implements a variation of frustum culling whereby we convert screen space clip rectangles into eye space mini-frustums so that we don't have to repeatedly transform actor paint-volumes all the way into screen coordinates to perform culling, we just have to apply the modelview transform and then determine each points distance from the planes that make up the clip frustum. By avoiding the projective transform, perspective divide and viewport scale for each point culled this makes culling much cheaper. |
