Right Conoid is a ruled surface. It is generated by moving a line segment S perpendicular to a fixed line L, in the direction of the L, while S rotates around L. When S has rotated 180 degrees, the direction of travel is reversed.
The construction of
Right Conoid is similar to a
Helicoid
The conoid has the same pinch-point singularity as the
Whitney Umbrella.
Here it is deformed into a helicoid
wireframe of a rotating right conoid.
The profile can become a circle or 2 triangles.
