Figure 24: Double-well surface

Equation: z = 0.12*(x^2-4)^2+0.2*y^2
Domain: x in [-3.0, 3.0]; y in [-3.0, 3.0]
Variables: dimensionless
Angle mode: radians
Camera: {'yaw': -48, 'elevation': 36, 'distance': 4.8}
Display: Native independent normalization: x/y -> [-1,1], z -> [-0.8,0.8]. Relative z/x exaggeration = 0.8*x_span/z_span. No vertex edits.
Sampled z range: [0.00047241926193237305, 4.8]
Mesh side: 129

Sampled mesh extrema may differ from exact function extrema; no coordinate labels are projected onto the image.

Caption: Global minima at (−2,0) and (2,0) have z=0. The stationary point at (0,0), z=1.92, is a saddle.

Alt text: Blue and orange quartic double-well surface with two troughs and a raised central ridge, on black.
