       Projector Classes -

   Classes
       class SbCylinderPlaneProjector
           The SbCylinderPlaneProjector class projects 2D points to a half-
           cylinder and a plane.

       This projector uses a plane along with the half-cylinder of
       SbCylinderSectionProjector for projections. If the 2D point mapping
       ’misses’ the cylinder section, the 3D point will be projected onto the
       plane. "
   class SbCylinderProjector
       The SbCylinderProjector class is the abstract base class for mapping to
       cylindrical surfaces.

       The cylinder projectors map 2D points to various surface types based on
       cylindrical shapes. "
   class SbCylinderSectionProjector
       The SbCylinderSectionProjector projects 2D points to a sliced cylinder.

       The projection cylinder for this class is sliced by a clipping plane
       parallel to its height axis. Projections will be mapped to the
       remaining cylinder part. "
   class SbCylinderSheetProjector
       The SbCylinderSheetProjector class projects 2D points to 3D points on a
       sheet covering a cylindrical shape.
   class SbLineProjector
       The SbLineProjector class projects 2D points to 3D points along a line.

       The 3D projection of the 2D coordinates is for this projector class
       constrained to lie along a pre-defined line. "
   class SbPlaneProjector
       The SbPlaneProjector class projects 2D points to 3D points in a plane.

       The 3D projection of the 2D coordinates is for this projector class
       constrained to lie inside a pre-defined 3D plane. "
   class SbProjector
       The SbProjector class is the abstract base projector class.

       Projectors are used in the Coin library for mapping 2D coordinates
       (typically from the position of the mouse cursor in the rendering
       window) to 3D ’world’ coordinates. "
   class SbSpherePlaneProjector
       The SbSpherePlaneProjector class projects 2D points to a half-sphere
       and a plane.

       This projector uses a plane along with the half-sphere of
       SbSphereSectionProjector for projections. If the 2D point mapping
       ’misses’ the sphere section, the 3D point will be projected onto the
       plane. "
   class SbSphereProjector
       The SbSphereProjector class is the abstract base class for mapping to
       spherical surfaces.

       The sphere projectors map 2D points to various surface types based on
       spherical shapes. "
   class SbSphereSectionProjector
       The SbSphereSectionProjector projects 2D points to a sliced sphere.

       The projection sphere for this class is sliced by a clipping plane.
       Projections will be mapped to the remaining sphere part. "
   class SbSphereSheetProjector
       The SbSphereSheetProjector class projects 2D points to 3D points on a
       sheet covering a spherical shape.

       The following stand-alone example shows how screen space coordinates
       projects into 3D when mapped with an SbSphereSheetProjector. It outputs
       the resulting projections as an SoPointSet in a Inventor-file on
       stdout: "

Detailed Description

       The projector classes are used to convert between screenspace (2D)
       locations and locations in worldspace (3D). They are mostly used in
       relation to user interaction with the mouse in the viewport.
