Re: 3d surface plot animation

Your program is too long and complex for me to comment on the speed
issues. Concerning color, I'm not sure exactly what your issue is. You
can calculate colors and then use them; for example you could do
something like mycolor = (1,1,k*z), where k*z is between 0 and 1, and
then set some object's color attribute to mycolor. Also note that the
faces object lets you specify the colors of all vertices individually.

A general comment about speed is that if you can structure a program
to use the parallelism of numpy arrays you can get large speedups in
the computations. Among the example programs that use this technique
are gas, stars, and toroid_drag. However, numpy can be rather hard to
use.
