Path Tracing

Path tracing is a computer graphics technique used to create highly realistic images by simulating the way light interacts with objects. It models the paths that light rays take as they bounce around a scene, reflecting, refracting, and diffusing to mimic natural lighting. By tracing many such paths from the camera to the light sources, it captures complex effects like shadows, reflections, and color bleeding with high accuracy. Although computationally intensive, path tracing produces images that closely resemble real-world scenes, making it popular for high-quality visualizations and movies.
