[vtkusers] Heavy Bug in DICOMAppHelper.cxx?

[Dipl.-Ing. Helmut Steiner]

Hi vtkusers!

 

Latest releases of vtk (starting from 5.2) have wrong vector product in
DICOMAppHelper.cxx. Am I wrong when I state, that the following calculation
makes right bodyparts look like left ones (dangerous thing
)?

Existing code is under comment, SHL – Patch is in lines following.

 

 //*****************************************************************

        //normal[1] = ((*sn_iter).second.ImageOrientationPatient[0]

        //             *(*sn_iter).second.ImageOrientationPatient[5])

        //  - ((*sn_iter).second.ImageOrientationPatient[2]

        //     * (*sn_iter).second.ImageOrientationPatient[3]);

       //*****************************************************************

        normal[1] = ((*sn_iter).second.ImageOrientationPatient[2]

                     *(*sn_iter).second.ImageOrientationPatient[3])

          - ((*sn_iter).second.ImageOrientationPatient[0]

             * (*sn_iter).second.ImageOrientationPatient[5]);

       //*****************************************************************
