Fine-grained backface culling

Backface culling is something we take for granted when rendering triangle meshes on the GPU. In general, an average mesh is expected to have about 50% of its triangles facing away from the camera. Unless you forget to set appropriate render states in your favorite graphics API, the hardware will reject these triangles as early in the rasterization pipeline as possible. Thus, it would seem that backface culling is a solved problem. In this post, however, we’ll explore a few alternative strategies that may or may not improve rendering performance.
