This page is designed to give you a sense of what your images should look like. In particular, it will show you the results that you should be getting as your progress through the implementations of the different features of the ray tracer. For all of these images, it is assumed that you have called:

% Assignment2 --in test.directional.ray --out test.bmp --width 640 --height 480 --rLimit 5 --cutOff 0.0001
