Geomorphs: Vase & Spear Head

Back to geomorph index



Definition of surface, in parametric equations:

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

where:

  • u ranges from 0 to 2, scanning a full circle on the XY-plane
  • v ranges from -2 to 2 if scanning the surface of the vase, and from -1 to 1 if scanning the surface of the spear head.
  • a is a constant having the value 2.47 in this plot.
  • b is a constant having the value 1.55 in this plot.

Ancestor: Bullet.

Descendants: None so far.
