[vtkusers] Image To PolyData

[Florian Schmidt]

Hi,

let's say i have a 3d-volume [vtkImageData] with only salar values of 0
in it except for some region which is marked with a 1. Is there a filter
that can produce polygonal data from this selection of voxels, so that i
can visualize the form of the marked region as a polygonal? 

Actually a filter that would produce a poly-cube for each marked voxel
and afterwards merges all connected cubes would work well..
