// .NAME vtkCylinder - implicit function for a cylinder
// .SECTION Description
// vtkCylinder computes the implicit function and function gradient
// for a cylinder using F(r)=r^2-Radius^2. vtkCylinder is a concrete
// implementation of vtkImplicitFunction. By default the Cylinder is
// centered at the origin and the axis of rotation is along the
// y-axis. You can redefine the center and axis of rotation by setting
// the Center and Axis data members. (Note that it is also possible to
// use the superclass' vtkImplicitFunction transformation matrix if
// necessary to reposition by using FunctionValue() and
// FunctionGradient().)
// .SECTION Caveats
// The cylinder is infinite in extent. To truncate the cylinder in
// modeling operations use the vtkImplicitBoolean in combination with
// clipping planes.
