Got Hierarchical Raytracing working... well sortof

Hey all,

Looks like I sortof have hierarchical modeling working, which is great!! That means I am essentially done this Raytracer Assignment and it's due next Tuesday so I am running way ahead of schedule - this is great cause at any given moment there are a good 20 things I could be doing. :) Anyway good times, Hierarchical Raytracing (where you just create a object, and then can apply Affine Transformations to it) seems to be working nicely. It also looks like Instancing is working, so if you have a diamond-shaped DAG, this is handled correctly and the objects are copied. I am having a problem with materials though and I am not sure what's going on, so I'll have to ask Matt for some advice when he gets back. Looks like my scene is a lot darker than the example scene, so that's no good. Also my shadows appear to be much darker than the sample scene, so I am not sure if there is some sort of problem with those.

Otherwise this seems to be working pretty well and when I get this stuff figured out I'll be pretty much done. I am going to add Reflections right now.

Oh yeah also I finished my Midterms today!!!!!!!!! Wahoo!!!!!!!!!!!!!!!! So that is totally awesome and I am really glad cause Midterm time is crazy. Now just going to do lots of work for the Extended Raytracer project. Awesome.
