![]() Photon mapping works by tracing photons from the light sources into the scene and storing these photons as they interact with the surfaces or volumes in the scene. ![]() When it comes to rendering caustics, photon mapping is an important factor. Examples of caustics include the light focusing through a glass, the shimmering light at the bottom of a swimming pool, and even the beams of light from windows into a dusty environment. With powerful software applications like Luxion KeyShot, more users can take advantage of RTX technology to speed up graphic workflows - like rendering caustics.Ĭaustics are formed as light refracts through or reflects off specular surfaces. NVIDIA RTX ray tracing has transformed graphics and rendering.
