Unity’s new Unified Ray Tracing API lets you trace rays against scene meshes on the GPU without requiring RTX hardware. In this video we build a simple example from scratch that generates rays, traces them against scene geometry, reads the hit results back on the CPU, and visualizes the results in the Scene view. This offers a powerful GPU alternative to `physics.raycast`, improving computer graphics and opening new avenues for optimization.
