I think he may be looking for a modeler, not a renderer.

I'm not sure what the interface for something like that would look like:
one slider bar (with textbox alternative) for each coefficient, with a
preview window?  Or would the textbox be sufficient?  A set of radio
buttons to increase the order of the surface, which will increase the
number of sliders/textboxes accordingly? Algebraic surfaces in general
don't really have control points, so the familiar click-and-drag of
patch control points won't work.
