Can anyone help me find software that can model algebraic and quartic
surfaces? I will also need it to be exportable in .StL or IGES file format
which includes the surfaces' normals.
Any ideas on where to go?

The superpatch is even better.

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.

The first place I'd go is the links section on www.povray.org . I
think I've seen several such utilities there.

It might be possible to fix the form of the polynomial (i.e.
degree and which coefficients are supposed to be nonzero),
then let the user move control points and solve the linear
system for the coefficients.
The real-time display might be a problem (there is no easy
parametrization even of curves of degree>2), so the program
will have to solve the polynomial just to display a wire mesh
or something similar.
