I am not sure if I understand your question, but It only plots
discrete data --- it takes some sympy expression, evaluates it on a
discrete grid and plots it. So you would just take the plotting stuff.

There are no dependencies besides pyglet (e.g.  it does not depend on
sympy, or if it does, it can be trivially fixed).

As to the API, just look into sympy/plotting. And play with the 3D
plots in sympy to see how it looks like and how fast/slow it is (I
think it's pretty fast). Then you will have to decide, if it's easier
for you to implement something from scratch, or take our stuff.

As I said, I would love if mpl has similar capability, so that we can
get rid of this from sympy. If you decide to go this way, I (and other
sympy developers) will be at hand to help you integrate it.
