[Insight-users] itkTriangleMeshToBinaryImageFilter support for partial overlap?

[wanlin]

Dženan,

   What version of ITK are you using? With the ITKv4, Your test failed
because of non-polygon cell type.  itkTriangleMeshToBinaryImageFilter should
work with partial overlap. However you must
ensure the triangle/polygon size small enough so the interaction between
edges of cell and slices of image could be detected.
