void	computeImage ()
	Raytraces the scene by calling tracePixel() for each pixel in the output image.
Protected Member Functions
Color	tracePixel (int x, int y)
	Computes the color of the pixel at (x,y) by sending a large number of rays through the pixel into the scene.

Detailed Description

Class implementing a simple path tracer.

The tracePixel() function is called for each pixel in the image, and is responsible for computing the output color by tracing a number of paths (rays) through the scene.
