DESCRIPTION

       SbCylinderProjector is an abstract base class for projectors that use a cylinder in their projection. The
       getRotation() method  for an SbCylinderProjector will always return a rotation that is about the axis  of
       the cylinder. Cylinder projectors are typically used to write interactive 3D manipulators and viewers.

METHODS

                         ~SbCylinderProjector()
          Destructor.

     SbVec3f             projectAndGetRotation(const SbVec2f &point, SbRotation &rot)
          Apply  the  projector  using the given point, returning the point in three dimensions that it projects
          to. This also returns in rot a rotation about the axis of the cylinder from the last  projected  point
          to  this  one.  The passed point should be normalized (i.e. lie in the range [0.0,1.0]), with (0,0) at
          the lower-left.

     virtual SbRotation  getRotation(const SbVec3f &point1, const SbVec3f &point2)
          Get a rotation given two points on this cylinder projector. The rotation will be about the axis of the
          cylinder.

     void                setCylinder(const SbCylinder &cyl)
     const SbCylinder &  getCylinder() const
          Set  and  get the cylinder on which to project points. The default cylinder is aligned with the Y axis
          and has radius 1.0.

     void                setOrientToEye(SbBool orientToEye)
     SbBool              isOrientToEye() const
          Set and get whether the projector should always be oriented towards the  eye.  Set  to  FALSE  if  the
          tolerance should be evaluated in working space.

     void                setFront(SbBool isFront)
     SbBool              isFront() const
     SbBool              isPointInFront(const SbVec3f &point) const
          Set and get whether the projector should intersect the half of the cylinder that faces the eye. Set to
          FALSE if the projector should intersect with the rear half.
