Dear VTK users,
  I am trying to use vtkObbTree for checking intersection between 2 objects.
For that i am interested to use IntersectwithOBBtree which is a function of
vtkOBBtree class.
      int vtkOBBTree::IntersectWithOBBTree  (  vtkOBBTree *    OBBTreeB,
      vtkMatrix4x4 *    XformBtoA,
      int(*    function)(vtkOBBNode *nodeA, vtkOBBNode *nodeB, vtkMatrix4x4
*Xform, void *arg),
      void *    data_arg


In this functionw what is vtkMatrix4*4 XformBtoA ,
 is it transform matrix.?
 i hope someone will clarify my doubt.
regards
Kannan
