Path Tracing Workshop
Now that GPUs have ray tracing units, real-time path tracing is coming into reach. Applications beyond movie rendering and baking embrace it, and therefore more people need to know about it. At Intel, I recently offered a path tracing workshop to educate a broad audience of engineers on basics of the topic. I am happy to announce that we decided to make this workshop publicly available. If you know a few math and programming basics, you can watch 76 minutes of videos and solve some exercises on ShaderToy as you go. In the end, you will have written your own ray tracer and a path tracer on top of it! I simplified things as much as possible, but you will really write all key aspects of the path tracer and understand why they work.
