Hi Bill,<div><br></div><div>Thanks for the reply. I made the change as you suggested. It does something now. The resulting scene has 10-20 polygonal structures that seem to be randomly located. They definitely don't represent the data. If I replace the thresholding and geometryfilter construction with a contourfilter, everything works fine; I get a surface reconstruction of the underlying cell population generated by marching cubes. What I need now is a visualization of the actual voxels that are ON, and to convert that to a polydata. Is vtkGeometryFilter the right class for that?</div><div><br></div><div>Any ideas?</div><div><br></div><div>Thanks,</div><div>Thommen<br><br><hr id="stopSpelling">Date: Tue, 10 May 2011 19:49:13 -0400<br>Subject: Re: [vtkusers] Visualizing populated voxels<br>From: bill.lorensen@gmail.com<br>To: thkorah@hotmail.com<br>CC: vtkusers@vtk.org<br><br>Try,<br><pre style="text-indent:0px">vtkDataObject<span style="color:rgb(0, 0, 0)">::</span>FIELD_ASSOCIATION_POINTS<span style="color:rgb(0, 0, 0)"><br>instead of<br></span>vtkDataObject<span style="color:rgb(0, 0, 0)">::</span>FIELD_ASSOCIATION_CELLS<br>

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>
