type 1 for hyperbolic paraboloid Z = X*Y type 2 for hyperbolic paraboloid Z = X² - Y² type 3 for infinite paraboloid Z = X² + Y² Examine shape by adjusting x & y rotation Adjust a and b for the X²/a and Y²/b Adjust color and other sliders Adjust a & b, parameters in Z = X²/a - Y²/b
Minimal code There's two ways to show a hyperbolic paraboloid: either Z = X*Y or Z = X² - Y²
