Geomorphs: Disc

Back to geomorph index

Definition of surface, in parametric equations:

x(u,v) = v cos(u)
y(u,v) = v sin(u)
z(u,v) = 0


  • u ranges from 0 to 2, scanning a full circle on the XY-plane
  • v ranges from 0 to 2, scanning the disc from the origin at its center to its rim at radius 2.

Ancestor: None: this is one of the original surfaces we hand-coded to get the geomorph "evolution" started.

Descendants: Bullet, Cochlea, Cone.
