/**
* @class vtkCylinder
* @brief implicit function for a cylinder
*
* 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().)
*
* @warning
* The cylinder is infinite in extent. To truncate the cylinder in
* modeling operations use the vtkImplicitBoolean in combination with
* clipping planes.
