Hi,
I can't give you example now (not on my computer).
But simply say that we have some VTK_QUAD (4 points) and VTK_VOXEL (8
points)
cells.

As cellTypes is a pointer, there is no problem:
cellTypes = [VTK_QUAD VTK_QUAD ... VTK_VOXEL VTK_VOXEL]

The problem comes from cellsSize, which is not a pointer but a
integer. So, as my cells have different size, how can I put these sizes
in vtkXMLWriterC_SetCellsWithTypes ?


I would suggest looking at the documentation of vtkCellArray and an

Ok, I'll look at asap.

Cheers,
