# 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

# specular (0.8,0.8,0.8) reflectivity.  The Phong exponent is 10 making the surface fairly shiny.
