Faster photon map global illumination
WebThe global illumination algorithm based on photon maps is a two-pass method. The first pass builds the photon map by emitting photons from the light sources into the scene and storing them in a photon map when they hit non-specular objects. The second pass, the rendering pass, uses statistical techniques on the photon map WebJul 23, 2024 · The photon mapping algorithm is an effective method for computing global illumination with its obvious advantage of caustic and color bleeding rendering. It is an active research field that has ...
