/**
* @class vtkCone
* @brief implicit function for a cone
*
* vtkCone computes the implicit function and function gradient for a cone.
* vtkCone is a concrete implementation of vtkImplicitFunction. The cone vertex
* is located at the origin with axis of rotation coincident with x-axis. (Use
* the superclass' vtkImplicitFunction transformation matrix if necessary to
* reposition.) The angle specifies the angle between the axis of rotation
* and the side of the cone.
*
* @warning
* The cone is infinite in extent. To truncate the cone use the
* vtkImplicitBoolean in combination with clipping planes.
