NAME

       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.

Constructor &; Destructor Documentation
   SbSpherePlaneProjector::SbSpherePlaneProjector (const floatedgetol = 0.9f, const SbBoolorienttoeye = TRUE)
       Default constructor. See SbSphereSectionProjector::SbSphereSectionProjector().

   SbSpherePlaneProjector::SbSpherePlaneProjector (const SbSphere &sph, const floatedgetol = 0.9f, const SbBoolorienttoeye = TRUE)
       Constructor with explicit specification of projection sphere.

Member Function Documentation
   SbProjector * SbSpherePlaneProjector::copy (void) const [virtual]
       Construct and return a copy of this projector. The caller is responsible for destructing the new instance.

       Note that if the Coin library has been built as a DLL under Microsoft Windows and you use this method from application code, you must make
       sure that both the Coin DLL and the application executable is using the same instance of a C Run-Time (CRT) library. Otherwise, you will
       get memory heap corruption upon deallocating the returned instances, eventually leading to mysterious crashes.

       Reimplemented from SbSphereSectionProjector.

   SbVec3f SbSpherePlaneProjector::project (const SbVec2f &point) [virtual]
       Project the 2D point from normalized viewport coordinates to a 3D point. The mapping will be done in accordance with the type of the
       projector.

       Reimplemented from SbSphereSectionProjector.

   SbRotation SbSpherePlaneProjector::getRotation (const SbVec3f &point1, const SbVec3f &point2) [virtual]
       Returns rotation on the projection surface which re-orients point1 to point2.

       Reimplemented from SbSphereSectionProjector.

   SbRotation SbSpherePlaneProjector::getRotation (const SbVec3f &point1, const SbBooltol1, const SbVec3f &point2, const SbBooltol2) [protected]
       Calculates rotation from point1 to point2, with tol1 and tol2 deciding whether or not to use the tolerance setting.

NAME

       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.
