"WebAug 4, 2024 · Ray tracing is a method of rendering in graphics that simulates the physical behavior of light. Tracing the rays from a surface on the screen to a light allows for the computation of shadows, but this can be challenging if the light comes from one point. And ray-traced shadows can quickly get expensive if there are many lights in the scene. " - Computer graphics shadows inverted
