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 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]
SbRotation SbSpherePlaneProjector::getRotation ( const SbVec3f point1,
const SbVec3f point2 
) [virtual]

Returns rotation on the projection surface which re-orients point1 to point2.
