Path tracing: A leap forward in photorealism for film, TV, and games

Path tracingIn real life, light comes from every direction and is reflected, scattered, and absorbed by every surface imaginable.

Replicating light’s natural behavior in computer-generated images and footage has always been a holy grail for animation, visual effects, and game development studios—path tracing brings this goal closer than ever.

Path tracing represents the evolution of older techniques such as rasterization, where an image is built from a single source of light, and ray tracing, which determines what’s visible at several points from different directions in the scene, letting you program more realistic scattering and impacting of light.
