Cone

A cone is defined by 4 parameters:

Parameter #	Description	Face Name	Face #
1	The z coordinate of the first point.	All Faces	0
2	The radial coordinate of the first point.	All Faces	0
3	The z coordinate of the second point.	All Faces	0
4	The radial coordinate of the second point.	All Faces	0

The line segment defined by the points is rotated about the z axis to form a section of a cone. This object can be used to make an annular or circular shape (if the two z coordinates are identical) or a cylindrical shape (if the two r coordinates are identical). In this sense the cone is redundant with the annulus and cylinder pipe objects. The cone is used as a primitive for creating Fresnel lenses.

The reference coordinate is locally (0, 0, 0), and the points that define the cone may be placed anywhere relative to the referencepoint. Face Numbers: All faces Face 0.
