All,<div> Is there a vtk filter that lets me interpolate a deformation field from an unstructured grid to an image data? From what I understand, vtkProbeFilter does the opposite (from vtkImageData to vtkUnstructuredGrid). </div>
<div> I built the unstructured grid by segmenting an image. The resolution of the unstructured grid is sparse when compared to the image (far few points in the unstructured grid when compared to the number of voxels in the image). I then solved a finite element model and obtained 3D displacements for every point in the unstructured grid. My goal is to interpolate the displacements from the unstructured grid back to the image (in other words deform an image using displacements at every point in the unstructured grid).</div>
