The Computational Alchemy of Ray Tracing: Illuminating Realism in 3D Worlds
1. Introduction: The Foundation of Realistic Illumination in 3D Ray tracing stands as a cornerstone technique in computer graphics, enabling photorealistic rendering by simulating the physical behavior of light. At its core, each ray traces from a virtual camera through pixels, intersecting 3D geometry to compute color, shadow, and reflection—mimicking...
