Ray mapping and illumination control
WebIn a subsequent pass, rays are traced from the eye into the scene to determine the visible surfaces, and the photon map is used to estimate the illumination at the visible surface points. [24] [25] The advantage of photon mapping versus bidirectional path tracing is the ability to achieve significant reuse of photons, reducing computation, at the cost of … WebJan 25, 2024 · Since the environment maps are pre-generated, they do not respond to changes in the scene and this is where reflection mapping majorly differs from ray-tracing. It is technically possible to retrieve the result from the next surface the ray hits in the scene. If this technique is used it would be considered ray-tracing and still capture some ...
