DESCRIPTION
SbSphereProjector is an abstract base class for projectors that use a sphere in their projection. Sphere projectors are typically used to write interactive 3D manipulators and viewers.
METHODS

}
projectAndGetRotation(const SbVec2f &point, SbRotation &rot)
Apply the projector using the given point, returning the point in three dimensions that it projects to. This also returns in rot a rotation on the surface of the sphere from the last projected point to this
one. The passed point should be normalized (i.e. lie in the range [0.0,1.0]), with (0,0) at the lower-left.

c
}
getRotation(const SbVec3f &point1, const SbVec3f &point2)
Get a rotation given two points on this sphere projector. The rotation will be on the surface of the sphere.

c
}
getSphere() const
Set and get the sphere on which to project points. The default sphere has radius 1.0.

setOrientToEye(SbBool orientToEye)
c

c
}
isOrientToEye() const
Set and get whether the projector should always be oriented towards the eye. Set to FALSE if the tolerance should be evaluated in working space.

isFront() const
c

c
}
isPointInFront(const SbVec3f &point) const
Set and get whether the projector should intersect the half of the sphere that faces the eye. Set to FALSE if the projector should intersect with the rear half.
