Tetgen will generate an unstructured grid for you. You need to provide it a
surface that defines the boundary of the mesh. tetgen does not read VTK
files directly, but you could easily convert the surface you have from
thresholding the volume to an STL or PLY file that tetgen can read. See,
e.g. [1]. If you are going this route, you just need to get the surface of
your volume - you can do this with the vtkContourFilter applied to your
full 3D stack of images.
