where h(u) is some function for representing the height of the moving line.
A typical example of right conoids is given by the parametric equations
The image on the right shows how the coplanar lines generate the right conoid.
Other right conoids include:
- Whitney umbrella:
- Wallis's conical edge:
- Plücker's conoid:
- hyperbolic paraboloid: (with x-axis and y-axis as its axes).
