Masked Software Occlusion Culling

Jon Hasselgren, Magnus Andersson & Tomas Akenine-Möller
Efficient occlusion culling in dynamic scenes is a very important topic to the game and real-time graphics community in order to accelerate rendering. We present a novel algorithm inspired by recent advances in depth culling for graphics hardware, but adapted and optimized for SIMD-capable CPUs. Our algorithm has very low memory overhead and is 3 faster than previous work, while culling 98% of all triangles culled by a full resolution depth buffer approach. It supports...
