Geomorphs: Trash Can

Definition of surface, in parametric equations:

x(u,v) = (b + v) cos(u)
y(u,v) = v sin(u)
z(u,v) = a v²

where:

u ranges from 0 to 2π, scanning a full circle on the XY-plane
v ranges from 0 to 2, scanning the can's surface.
a is a constant having the value 2.47 in this plot.
b is a constant having the value 2.84 in this plot.

Ancestor: Bullet.

Descendants: None so far.
