Lecture 9: Intro to Ray-Tracing & Accelerating Ray-Scene Intersection (27)
EwayZ001
I know there are serval ray-tracing technologies exists nowadays. For example, Nvidia has their ray tracing technologies which called "RTX". RTX 40 series can runs complex scene with ray tracing in 4K. However, what makes it possible for a GPU to render those incredibly ray-tracing graphic in 4K 60 FPS? What are some core technologies or optimization behinds it and make it different from others?

These new NVIDIA GPUs have RT cores, which are ASICs that enable fast ray tracing. They can perform aa massive amount of ray intersection tests with BVHs very quickly, enabling real time ray tracing.
