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. WebTo compute the refraction direction we also need to specify the index of refraction of the material. Although we said earlier that rays travel on a straight line, we can visualize refraction as the ray being bent. When a photon hits an object of a different medium (and thus a different index of refraction), its direction changes.
