usage: build a deformation field between 2 meshes (same mesh before and after deformation)
       [-h] [-i INPUT] [-j INPUT2] [-o OUTPUT]

options:
  -h, --help            show this help message and exit
  -i INPUT, --input INPUT
                        mesh before deformation
  -j INPUT2, --input2 INPUT2
                        mesh after deformation
  -o OUTPUT, --output OUTPUT
                        deformation field (Volume of Point3DF, use .ima
