HW11: Blurry Shadows

CS 481/681 2007 Homework, Dr. Lawlor

Make a moving object cast a global-illumination-style blurry shadow.  You can choose how you want it to move, for example via a rotation matrix, or by moving the sphere center like a particle (under influence of gravity and a constraining ground plane).  You can also choose any blurry shadow algorithm you like, although be warned my 481_radiosity2 raytracer example code as written doesn't actually allow the occluder center to change--the conetracer version should be fine, though!

This assignment is due at midnight on Thursday, April 19.  Please turn in enough source code for me to run your program--probably at least a main.cpp and fragment.txt.  Turn everything in on blackboard.
