[vtkusers] 3D points marking the boundaries of the nonblack regions

[Helder Carvalho]

Hi,

I have 6 vtk binary images, which were imported from ITK, that are slices of 
a 3D volume. I want to generate 3D points marking the boundaries of the 
nonblack regions in each of the images. Any ideia on how to do that would be 
appreciated.

Regards,
Helder Carvalho
