Ray Tracing | Vibepedia

Ray tracing is a sophisticated rendering technique in 3D computer graphics that simulates the physical behavior of light to generate highly realistic images. Unlike traditional rasterization, which projects 3D objects onto a 2D screen, ray tracing follows individual light rays from the camera's viewpoint back into the virtual scene, calculating their interactions with surfaces. This method accounts for complex optical phenomena like reflections, refractions, and shadows with remarkable accuracy, leading to unparalleled visual fidelity. Historically confined to offline rendering for film and architectural visualization due to its computational intensity, ray tracing has seen a dramatic resurgence with hardware acceleration in modern GPUs, enabling its use in real-time applications like video games since around 2018. This shift has fundamentally altered the landscape of digital content creation, pushing the boundaries of what's visually possible.
