// .NAME vtkConeSource - generate polygonal cone
// .SECTION Description
// 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.

// the cone. Warning: this is not the center of the base of the cone!
// The default is 0,0,0.
