Examine shape by adjusting x & y rotation Adjust color and other sliders Adjust a & b, parameters in Z = X²/a - Y²/b
Hyperbolic Paraboloid as Z = X² - Y² I like it that simple way, but coded it X²/a - Y²/b so that we can adjust a and b. Minimal code I also did one with z = x*y. Compare with that. My earlier hyperbolic parabolas used a completely different method, drawing lines
