Ray tracing is a technique for modeling light transport in 3D computer graphics. It can simulate various optical effects, such as reflection, refraction, shadows, and sound waves, but requires more computational cost and time than scanline rendering methods.
A comprehensive list of free and commercial software for producing ray-traced images. Compare the features, licenses, platforms and availability of various ray-tracing software products.
Learn how to use ray transfer matrices (ABCD matrices) to perform ray tracing calculations for optical systems. Find the matrices for free space, refraction ...
Nvidia RTX is a visual computing platform that supports real-time ray tracing and artificial intelligence integration. It runs on Nvidia GPUs based on Volta, Turing, Ampere and Ada Lovelace architectures and is used for gaming, professional workstations and simulation.
Conventional ray tracing uses single rays to sample many different domains. For example, when the color of an object is calculated, ray tracing might send a single ray to each light source in the scene. This leads to sharp shadows, since there is no way for a light source to be partially occluded (another way of saying this is that all lights ...
Learn about the special-purpose computer hardware designed for accelerating ray tracing calculations, from early experiments to modern GPUs. Compare different approaches, features, and performance of ray tracing hardware across various products and platforms.
Physically based rendering (PBR) is a computer graphics approach that models the lights and surfaces with optics in the real world. PBR uses textures, shaders, and mathematical models to create photorealistic images, and is often used in video games, movies, and other applications.
Intel Arc is a brand of graphics processing units designed by Intel for the high-margin PC gaming market. The first generation of Arc GPUs (codenamed Alchemist) launched in March 2022, using TSMC N6 process and supporting ray tracing, XeSS and DirectX 12 Ultimate.
