Assignment 1
PBRT Build
I compiled it in Visual Studio 2005 without any major issues. The pbrt folder needed to be located at C:/pbrt which I didn't realize initially, but once I put it there and edited the paths as noted in PBRTInfo everything compiled without errors.
Rendering
The images rendered in ~ 1 sec at 150x150 with 1 sample and no subdivision, so no additional optimization was really required. However, it was surprising how much slower it was at 400x400 with 4 samples and level 3 subdivision - it took ~30 seconds.
