Join Christos Obretenov for an in-depth discussion in this video Path tracer vs. VCM integrators: A technical breakdown, part of Pixar's RenderMan Essential Training.
- [Voiceover] So let's take a look at…the PatchTracer vs. the VCM, the bi-directional…path tracer, in a lot more detail.…We didn't see too much of a difference there…in our simple scene, but we'll take a look at some…renders and diagrams to really get at the intricacies…between the two, because they're quite different,…and we'll find out what the V, C, and M stand for.…So here's a great still life scene that we'll be…rendering with in this course a little bit later on.…We got this off the RenderMan community site,…it's for a free download there, and we rendered this…with the PathTracer on the left and that took 26 minutes,…and it's a complicated scene, there's a lot going on.…
There's omissive lights on the candles,…we'll take a look at omissive lights as well.…There's glass, there's actually subsurface scattering inside…the teapot because it's like a ceramic material, and also…on the grapes, and refraction going through the glass.…So one of the things that we can notice if we go look…at the right with the VCM, that took significantly longer,…
