Isn't path tracing a subset of ray tracing?
- NikosVitsas 6y agoI would see it’s the other way around. A path is definitely a more generic term than a ray.

- hellofunk 6y agoYes, maybe for the individual English words "path" and "ray", but as a graphics term, path tracing is a subset of a larger area called ray tracing. There are many, many different forms and algorithms for ray tracing, and path tracing is one of those.
- viscoelastic 6y agoHowever paths are made out of rays. So the basic technology implemented on the GPU is to calculate intersections or rays against geometry, raytracing, which is the basic building block of path tracing and several other classes of algorithms.
- rendaw 6y agoPart 1 even says > Path tracing is a type of ray tracing contradicting itself.
- dahart 6y agoThis isn’t actually a contradiction unless you misunderstood one of the two sentences. Try assuming both statements are true at the same time, and then think about what that implies.
