Bovines in the Information SuperPasture
Cows in Computer Graphics
For a long time now, the teapot has been a canonical model and symbol
of computer graphics. As you can see, the teapot is rather
uninteresting. In fact, you might even go so far as to say that it is
rather sterile. The cow, on the other hand, is fully organic. The
bovine form offers both greater appeal and greater complexity. I
firmly believe that if I were to spend hours working on and testing my
software using a teapot, I would be bored. A teapot tumbling through
space is a common occurence. You can reproduce this effect in your
very own kitchen. However, a cow tumbling through space is
something that you definitely do not see every day. This can increase
the entertainment value of otherwise dull software by that critical
amount necessary to maintain interest at levels sufficient for

This 3D model of a cow, in Wavefront OBJ format, should provide you with the raw data necessary to start using cows in your own graphics projects.
Want to use a cow in a radiosity environment? Tired of calculating form factors for every single miniscule little polygon on the surface of the cow? Your difficulties are at an end. Some intrepid researchers have computed the form factor of a cow. Check out the paper:
Perry, R.L., and Speck, E.P. "Geometric Factors for Thermal Radiation Exchange Between Cows and Their Surroundings", American Society of Agricultural Engineers Paper #59-323.
I've taken the liberty of entering the summary for this paper. It should give you a feel for what the paper's about.
