Jean, I have added a patch to Bug 0000867 called surface.patch. I would like you to run it on your machine. And let me know about performance issues.

Thanks
Mathieu

I have made the following tests:

nb of hexaprisms | exec time
-----------------------------
    10,000 | 0.035 seconds
   100,000 | 0.345 seconds
 1,000,000 | 3.370 seconds
10,000,000 | Abort

Performance seems linear and that is great. The Abort is all I got for error message. The input file is 400 Mbytes, I have 2G available. I don't know yet why it crashes.

I would guess that the same hash table for the penta-prisms will work just fine.

NOTE:
vtkDataSetSurfaceFilter can be used on quad elements if first pass through vtkDataSetTriangleFilter + vtkCleanUnstructuredGrid.

Otherwise we need a patch similar to surface.patch but with a number of point = 9 (quadratic quad face)
