A dicone is a special case of a pyramid where the base is a cone. It is also a special case of a dipyramid where the base is a circle. It is bounded by two cones and an arrinder.

Equations

  • Variables:
r ⇒ radius of base of dicone
h ⇒ height of dicone
  • All points (x, y, z, w) that lie on the surface of a dicone will satisfy the following equations:
