x(u,v) = cos(v) cos(u)
y(u,v) = sin(v) cos(u)
z(u,v) = sin(u - a)
where:
- u ranges from -ð/2 to ð/2, scanning a half circle from the pointed tip at top to the rounded end-point at bottom.
- v ranges from 0 to 2ð, scanning a full circle on the XY-plane.
- a is a parameter ranging from 0 to 2ð with a step of ð/32, giving the 64 frames shown here. When a = 0 the drop is reduced to its ancestor, the sphere.
Ancestor: Sphere.
Descendants: Castanuela.
