What is the difference between Radiosity and Ray Tracing?
I found the below PDF material (Resource from MIT) provides a good answer to this question:

What is the difference between
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 namedpath tracing. Let's see how Disney explains the theory: Disney's Hyperion Renderer -
