OptiX is since 2009, real time ray tracing API based on CUDA. Good for intensive complex scene and rendering is fast.
DXR and VKR are more for real time applications like games. However, DXR is on Windows and X-box. Great API for windows
Vulkan works on windows and linux.

Path tracing aka. Physically based rendering (PBR) is a discrete light simulation that approximately imitates the continuous real-world light interaction using the approximate physics and calculus algorithm. The goal of this repository is to gather available resources that will help beginners start working in path tracing (PBR).
