* @class vtkCylindricalTransform
* @brief cylindrical to rectangular coords and back
*
* vtkCylindricalTransform will convert (r,theta,z) coordinates to
* (x,y,z) coordinates and back again. The angles are given in radians.
* By default, it converts cylindrical coordinates to rectangular, but
* GetInverse() returns a transform that will do the opposite. The
* equation that is used is x = r*cos(theta), y = r*sin(theta), z = z.
* @warning
* This transform is not well behaved along the line x=y=0 (i.e. along
* the z-axis)
* @sa
