Morphed Tetrahedral Bezier Surfaces
Morphed Tetrahedral Bezier Surfaces
You can morph this Bezier surface into four types of tetrahedral surfaces:
1) a ruled elliptical tetrahedron
2) a classical Berlingot simple tetrahedron
3) a negatively curved standing wave tetrahedron
4) a projective tetrahedron
The intermediate morphed surfaces are also interesting.
