Assignment 1
PBRT Build/Installation
I built pbrt on Ubuntu. For some reason Ubuntu's Synaptic only had an old version of openexr, so I had to get openexr 4.0 from the openexr website. Otherwise there were no problems.
Rendering Process
To save time I rendered at 200x200 with pixelsamples set to 2.
Experimentation / Other Cool stuff
I played around with multi-colored lights, which looks pretty neat.
According to the TA there is a bug in pbrt. pbrt claims to use a left-handed coordinate system, but when we tried to work this out with one of the scene files it turned out that the shadow was on the wrong side. I would appreciate it if this could be clarified.
