[vtkusers] vtkPolyDataToImageStencil : limits ?

[Mathieu Malaterre]

Hi all,

	Does anyone of you knows the limits of vtkPolyDataToImageStencil when 
use with a vtkImageStencil ?
	I am experiencing some bizarre things, for snapshot go here:

	http://www.creatis.insa-lyon.fr/~malaterre/vtk/ImageStencil/
(png files are extracted from 'image.vtk')

	My polydata is closed (I use vtkFeatureEdge to check that). But I don't 
see what other properties could let vtkImageStencil and/or 
vtkPolyDataToImageStencil to fail.

	I also send a script: 
http://vtk.org/pipermail/vtkusers/2003-September/019973.html
	that uses a polydata with high dihedral angle and there doesn't seems 
to be such problem.

Thanks for your explanations.
