To run the computations, one needs:
– to align the surfaces with a reference surface
– to generate a template used as initial mean shape
– to edit xml files (data_set.xml, model.xml et optimization_parameters.xml)
The alignement has been processed with Avizo and the tool Align surfaces (rigid alignement with scale) by choosing a random reference. The script align_surfaces_from_refererence_with_uniform_scale.hx disponible ici has been used.
The template has been generated by computing the geometrical mean of several surfaces, which is possible here because all surfaces own the same number of points in the same order (it is not the case gnerally).
Then the parameter files has been generated by the code of Tools for Deformetrica:
python atlas_file_edition.py
We get data_set.xml, model.xml et optimization_parameters.xml and launch_simulation_python.sh used to launch the computations.
The computations can be done by running launch_simulation_python.sh under linux (a good graphic card supporting CUDA is needed):
bash launch_simulation_python.sh
