Efficient Triangle Coverage Tests for Stochastic Rasterization
Samuli Laine, Tero Karras · 2011
In our previous paper on stochastic rasterization [Laine et al. 2011], we stated that a 5D triangle coverage test consumes approximately 25 FMA (fused multiply-add) operations. This technical report details the operation of our coverage test. We also provide variants specialized for defocus-only and motion-only cases. 1 A Basic 5D Test Let us denote the three moving input vertices as v0(
