Assignment 4
Marc Burns - m4burns - 20368400
CS 488 Spring 2013, University of Waterloo
1 Manual
1.1 Program Operation
The submitted rt executable meets the objectives specified with the following deviations:
i. Bounding boxes are unimplemented.
ii. Numerical errors occur when mesh faces with normal near-orthogonal to the ray direction are
drawn.
iii. Shadow rays are unimplemented.
In all three cases, I ran out of time. I have a midterm tomorrow and I had a midterm last week.
I implemented stochastic sampling from the Cook feature as my extra feature. I used five uniformly
distributed subsamples per pixel, and a box filter (average of colour values) to compute the final pixel.
The provided rt executable is multi-threaded (renders in up to 8 threads at once) using GNU
OpenMP (a compiler feature). Some C++0x features were used.
