  If you a concerned about time maybe you shouldn't be raytracing :)

Seriously the few minor adjustments I made to your Hf code added little
to nothing extra to the render time. Add to that the fact that they
give you better control over your textures they should not be dismissed
out of hand. Adding reflection, phong and specular highlights, and
things like area lights are what really add greatly to render times and
not the simple ambient and diffuse settings I threw in there.
