SbSphereProjector — sphere projector

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.

SbVec3fprojectAndGetRotation(constSbVec2f&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.

     virtualSbRotationgetRotation(constSbVec3f&point1,constSbVec3f&point2)
          Get  a  rotation given two points on this sphere projector. The rotation will be on the surface of the
          sphere.

     voidsetSphere(constSbSphere&sph)constSbSphere&getSphere()const
          Set and get the sphere on which to project points. The default sphere has radius 1.0.

     voidsetOrientToEye(SbBoolorientToEye)SbBoolisOrientToEye()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.

     voidsetFront(SbBoolisFront)SbBoolisFront()constSbBoolisPointInFront(constSbVec3f&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.
