Please download our MATLAB codes and run the main file to use the SSMs and SDMs of the humerus and scapula bones.
The SSM will create a surface model whose shape is sensitive to the normalized PC scores chosen in the app. The SDM will apply node-by-node HU values to a 3D template volumetric mesh (from the average geometry), allowing you to visualize the bone density distribution which is sensitive to the normalized PC scores chosen in the app.
The output files can be visualized using open-source software like ParaView (www.paraview.org).
