Geomorphs: Sphere

Back to geomorph index

Definition of surface, in parametric equations:

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


  • u ranges from 0 to 2, scanning a full circle on the XY-plane
  • v ranges from -/2 to /2, scanning a half-circle on the XZ- (or YZ-) plane.

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

Descendants: Drop, Facing Snails.
