Assignment 2 related questions

Homework 2 has been posted. Use this blog entry's comment section for posting Q&A related to this assignment.

Update 2: The color specification has been changed to provide ambient, diffuse and specular components for red, green and blue seperately. For the sample input, the vertex and light source specification has been corrected.

Update 3: Use the standard obj file format (and a standard reader) for the input model specification. You should have received Dave's sample input by mail.

Update 4: Minor errors in the sample obj files fixed (by Dave Crist): Heres the latest version:
obj files

Here are some sample outputs from a previous semester (Thanks again, Dave!). Note that the top surface is missing in both cases - this is probably a bug.

Image 1: 200x200 image, 10 samples per pixel, 2 levels deep (reflections):

Image 2: 200x200, 20 samples, 5 levels:
