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.

SYNOPSIS

       #include <Inventor/projectors/SbSpherePlaneProjector.h>

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 float edgetol = 0.9f,
       const SbBool orienttoeye = 1) Default constructor. See
       SbSphereSectionProjector::SbSphereSectionProjector().
   SbSpherePlaneProjector::SbSpherePlaneProjector (const SbSphere & sph, const
       float edgetol = 0.9f, const SbBool orienttoeye = 1) 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 SbBool tol1, const SbVec3f & point2, const SbBool tol2)
       [protected] Calculates rotation from point1 to point2, with tol1 and
       tol2 deciding whether or not to use the tolerance setting.
