// .NAME vtkCylinder - implicit function for a cylinder
// .SECTION Description
// vtkCylinder computes the implicit function and function gradient for a
// cylinder. vtkCylinder is a concrete implementation of vtkImplicitFunction.
// Cylinder is centered at Center and axes of rotation is along the
// y-axis. (Use the superclass' vtkImplicitFunction transformation matrix if
// necessary to reposition.)
// .SECTION Caveats
// The cylinder is infinite in extent. To truncate the cylinder use the
// vtkImplicitBoolean in combination with clipping planes.
