NAME
SbSpherePlaneProjector
SYNOPSIS
#include <Inventor/projectors/SbSpherePlaneProjector.h> Inherits SbSphereSectionProjector.
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.

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.

- 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.

Calculates rotation from point1 to point2, with tol1 and tol2 deciding whether or not to use the tolerance setting. - References SbVec3f::cross(), SbVec3f::dot(), SbSphere::getCenter(),
