Hi,<div><br></div><div>I have a voxel grid (stored as vtkImageData). I would like to visualize the cells that are populated (greater than a particular threshold). I then want to convert the resulting surface into a polydata and write it as a PLY file. My code below that uses vtkThreshold followed by GeometryFilter doesn't work for some reason. Could anyone suggest a possible fix?</div><div><br></div><div>Thanks.</div><div>Thommen</div><div><br></div><div><meta name="qrichtext" content="1"><style type="text/css">
