- Ray Tracing in One Weekend (raytracing.github.io)
I’ve taught many graphics classes over the years. Often I do them in ray tracing, because you are forced to write all the code but you can still get cool images with no API. I decided to adapt my course notes into a how-to, to get you to a cool program as quickly as possible. It will not be a full-featured ray tracer, but it does have the indirect lighting which has made ray tracing a staple in movies. Follow these steps, and the architecture of the ray tracer you produce will be good for extending to a more extensive ray tracer if you get excited and want to pursue that.
