Resources of Ray tracer and Path tracer

Ray tracing

Here are the useful resources about ray tracing I found today:

• CPU ray tracer using C++ (by Peter Shirley): https://raytracing.github.io/

  (I also highly recommend his ray tracing book: Advanced Global Iluumination, which explained the theory of tracing in math-physical formula real nice.)

• GPU ray tracer using Vulkan: https://github.com/grigoryoskin/vulkan-compute-ray-tracing

• GPU ray tracer using OpenGL3.1 (back to my 2021 TAing): https://github.com/yuantianle/Ray_Tracing-Sep2021

Path tracing

• Instead of doing ray tracing, we can optimize the calculation by only caring about the camera's input - we get a method named path tracing. Let's see how Disney explains the theory: Disney's Hyperion Renderer

• CUDA path tracer (by YINING KARL LI): https://www.yiningkarlli.com/projects/gpupathtracer.html
