Code for CSC418 Computer Graphics Assignment 3 Ray Tracer

File Descriptions:

raytracer.{cpp, h} The main body of the raytracer, including the scene graph. Simple addition and traversal code to the graph are provided to you.

util.{cpp, h} Includes definitions and implementations for points, vectors, matrices, and some structures for intersection and shading.

light_source.{cpp, h} Defines the basic light class. You could define different types of lights, which shades the ray differently. Point lights are sufficient for most scenes.

scene_object.{cpp, h} Defines object primitives in the scene (spheres, cylinders, etc...).
Implements the intersect function which finds the intersection point between the ray and the primitive.

bmp_io.{cpp, h} I/O functions for .bmp files. You shouldn't have to modify them.
