Thanks for your reply - I have a much better feel for for parallel is implemented in VTK now. Below is a patch for SurfaceMap.py. Similar patches will be need for many modules and filters. I'm guessing the same is true for MV2. $ cvs diff Modules/SurfaceMap.py Index: Modules/SurfaceMap.py =================================================================== RCS file: /cvsroot/mayavi/mayavi/Modules/SurfaceMap.py,v retrieving revision 1.12 diff -r1.12 SurfaceMap.py 42c42,45 < self.map.SetInput (mod_m.GetOutput ()) --- > internal_surface_filter = vtk.vtkDataSetSurfaceFilter () > internal_surface_filter.SetInput (mod_m.GetOutput ()) > internal_surface_filter.SetPieceInvariant (1) > self.map.SetInput (internal_surface_filter.GetOutput ()) ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ MayaVi-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mayavi-users
