    Algebraic surface equation:

Polynomials can be entered in both rational and floating-point formats, coefficients of arbitrary length are accepted:
for example, 5/7x^4-5x^2+y^4-4y^2+1.075z^4-33/4z^2+11.788 is a valid input.

For technical reasons, high-performance computations on the GPU for crucial subroutines are currently disabled.
Please expect significantly reduced performance of the curve and surface analysis and visualization. We apologize for the inconvenience.
