# Greg Mayer, 2009

# A camera looking from (0,0,6) down the negative z-axis (0,0,-1) with up in the direction (0,1,0) 
# The xfov is 0.5, while the yfov will be computed to match the aspect ratio of the image
# The near and far distances are 0.01 and 100, which conservatively contain the scene

# Two directional lights, one white (1,1,1) pointing in the direction (-3,-4,-5)

# A gray surface material with some ambient (0.2,0.2,0.2), diffuse (0.5,0.5,0.5), and 
# specular (0.8,0.8,0.8) reflectivity.  The Phong exponent is 10 making the surface fairly shiny.
