Ray Tracer Part 3 - Shading

Phong Illumination on Scene

The purpose of this assignment was to implement the Phong Illumination model in the ray tracer assignment. In this picture there are 3 light models (format: (r, g, b, intensity)):

ambient ( 1, 1, 1, .2 ) 

diffuse ( .4, .4, .4, 1 ) 

specular ( 1, 1, 1, 1

For an "Extra", I implemented another Light Source. 

To show the differences with the different light sources and experiment with colors, I made the spheres an off-white (0.9, 0.9, 0.9). The Normal light source is the same as the light source above. The new light sources have the following model specifications: 

Red Light 
specular ( 1, 0, 0, 1 )
diffuse ( 1, 0, 0, 1)

Green Light
diffuse ( 0, 1, 0, 1 )
specular ( 0, 1, 0, 1 )

Blue Light 
diffuse ( .1, .1, 1, 1 )
specular ( .1, .1, 1, 1 )

3 light sources, Red, Green, and Blue
