/**
* @class vtkConeSource
* @brief generate polygonal cone
*
* vtkConeSource creates a cone centered at a specified point and pointing in
* a specified direction. (By default, the center is the origin and the
* direction is the x-axis.) Depending upon the resolution of this object,
* different representations are created. If resolution=0 a line is created;
* if resolution=1, a single triangle is created; if resolution=2, two
* crossed triangles are created. For resolution > 2, a 3D cone (with
* resolution number of sides) is created. It also is possible to control
* whether the bottom of the cone is capped with a (resolution-sided)
* polygon, and to specify the height and radius of the cone.
