Tracing Rays in Real Time
summary
Covers real-time rendering methods, first explaining rasterization and its limitations, then ray tracing and the possibilities it enables. Uses NVIDIA RTX and the Vulkan ray-tracing extension, with Node.js code examples, and outlines how to start building a ray tracer in JavaScript today.
