WebDec 1, 2024 · Ray tracing: Explained. As a graphic technology, ray tracing allows for the fluid simulation of lighting effects. An algorithm emits rays in the form of a 3D graphic, traces the rays’ paths and then calculates a realistic lighting model. Anyone that is familiar with computer games and graphics cards will inevitably be familiar with ray ... WebOct 24, 2024 · Path tracing is a type of ray tracing. When using path tracing for rendering, the rays only produce a single ray per bounce. The rays do not follow a defined line per bounce (to a light, for example), but rather shoot off in a random direction. The path tracing algorithm then takes a random sampling of all of the rays to create the final image. cindee carlson
