I've tried to compile the code, and it seems that one needs to have a version of VTK greater than the latest release to run this without compilation errors. Specifically, you use vtkMath::Subtract, which is not included in 5.4.2. I'll upgrade to the nightly build and post the results on the midas journal page.<br>

Thank you! I'll let you know how it works out. How can I add this to my Paraview setup?<div><div></div><div></div></div></blockquote></div><div><br></div></div>Let's keep the discussion on the mailing list so everyone can input and benefit.<div>
<br><div>As it was part of a bigger submission (surface reconstruction), I didn't wrap vtkVoxelizePolyData directly. I just tried to quickly make it into a Paraview plugin, but it seems I have separated the code a bit differently than I remember.</div>
<div><br></div><div>vtkVoxelizePolyData simply creates the vtkImageData with reasonable bounds over the polydata. Computing the distance to the surface was actually done in vtkPointSetSurfaceReconstrion, and then I used a vtkContourFilter to extract the 0 level set (the surface). You can definitely reuse most of this code - you just have to check the sign on the SignedDistanceToPlane function and mark the point as inside or outside.</div>
<div><br></div><div>You could also ust vtkVoxelizePolyData to make the grid, then use something like this:</div><div><a href="http://www.vtk.org/Wiki/VTK/Examples/PointInsideObject" target="_blank">http://www.vtk.org/Wiki/VTK/Examples/PointInsideObject</a></div>
<div><br></div><div>on every point to do the inside/outside marking.</div>
