WebJan 21, 2024 · Rasterisation is very efficient at solving this problem from primary rays (or camera rays) and less efficient to solve this problem for secondary rays (reflection, refraction, shadows, etc.) than ray-tracing. Ray-tracing is slower than rasterisation for primary rays but offers a simpler solution for secondary rays compared to rasterisation.
