ToyMan is a prototypical micropolygon renderer I wrote at around 2010 or 2011. It probably supports basic micropolygon dicing, distribution effects, and environment lighting, and point-based global illumination. I probably took some code from pbrt version 1 and I probably was inspired by the Pixie renderer. I probably was reading the book Production Rendering: Design and Implementation at the time. Below are some images I salvaged from my old directory.
I am not sure if this code would be useful to anyone, but I want to keep it for fun.
