Detailed Description

template<typename T, int NDIMS>
class axom::primal::Cone< T, NDIMS >

Represents a cone defined by a base radius, a top radius, the length, the orientation and the location of the base center.

Template Parameters

T	the coordinate type, e.g., double, float, etc.
NDIMS	the number of spatial dimensions

Negative length is allowed and leads to negative volume. Radii must be non-negative.

A cylinder can be represented using equal base and top radii.
