[vtkusers] vtkPolyData exported to OpenInventor

[Dennis Jen]

Were you able to render anything?  I think i had tried to decimate after a
triangle filter once and it didn't work.  If you're not able to render
anything, try a simplier pipeline first:

vtkContourFilter -> vtkTriangleFilter -> vtkStipper -> vtkPolyDataNormals
...

I hope that helps.

Hi all,

I have a vtkPolyData with these filters :
vtkContourFilter -> vtkTriangleFilter -> vtkDecimatePro ->
vtkSmoothPolyDataFilter -> vtkPolyDataNormals -> vtkStripper ->
vtkCleanPolyData

I can export it to a OpenInventor (iv) file with the vtkIVWriter.
I have updated my vtk version with the nightly release to fix some bugs
in these class.

I'd like to use the MESH program http://mesh.epfl.ch/ to compute
differences between two meshes.

This program said that my poly is: "empty (no faces)"

What can I do to fix this?
Wich filter should I add in my pipeline to have faces?

Thanks

imho
