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.

Detailed Description

       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.
