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.
