[vtkusers] help with marchingcubes with dicom slices set

[kingvsk at aol.com]

Please comment the following lines from that code.

         //vpanSurface.GetRenderWindow().StereoCapableWindowOn();
////vpanSurface.GetRenderWindow().SetStereoTypeToAnaglyph();
//vpanSurface.GetRenderWindow().SetStereoTypeToCrystalEyes();
         //vpanSurface.GetRenderWindow().SetStereoRender(1);

These lines are used to enable stereo 3D view.  Sorry for the trouble.
