How Ray Tracing (Modern CGI) Works And How To Do It 600x Faster

An explanation of ray tracing fundamentals and how the ReSTIR algorithm achieves massive speedups for dynamic global illumination.

In which we explore ray tracing, the reason modern CGI can look so convincing, and ReSTIR, a recent technique that allows images (and particularly animations) to be rendered hundreds of times faster.
