How can I create a vtk structure point file from vtk unstructured grid file?

Question

I have an unstructure grid in vtk file ( with legacy format), these file describe a points, cells and cell type. How can I generate a vtk structured point from this unstructure grid ?, or a 3d image file (with voxel information)?

Answer 1

You can start converting your vtkUnstructuredGrid to a vtkPolyData, see an example here . Then you can use vtkImplicitModeller to build a vtkImageData (voxels) from your vtkPolyData, see an example here . These are C++ examples, I'm sure you can find Python examples if needed.
