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.

SbSphereSectionProjector::SbSphereSectionProjector().

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.
