Lecture 13: Global Illumination & Path Tracing (100)
adham-elarabawy
Something that is very interesting to observe is that including more bounces of light seems to introduce different textures in the image. I'm not sure if those textures are actually evident or if this is a manifestation of noise, but it is really interesting how grainy the image gets when including all bounces of light. I would love clarification here!

@adham-elarabawy I was wondering the same thing because on inspection of this picture compared to direct lighting with 0 and 1 bounce light only, this picture seems a lot more grainy and noisy. This seems a bit counterintuitive if this is actually texture and not just noise, considering we are taking more samples and the next few slides show how tracing more paths results in a smoother image.
