3D Function Surface Plotter and Sampler

Plot z=f(x,y) as a rotatable 31×31 sampled surface. Adjust the X/Z view, save a PNG, or export the separate 11×11 coordinate table. This is numerical sampling, not an analytic or discontinuity-aware graphing system.

z=x*x+y*y; x,y∈[-2,2]
(0,0) → z=0
(2,2) → z=8
31×31 → surface PNG
11×11 → x,y,z CSV

X (°) / Z (°)
← ↑ → ↓
