Surface human body meshes suitable for electromagnetic (and acoustic) modeling were obtained with a 3D Model WB4 laser scanner manufactured by Cyberware at U.S. Army Natick Soldier Research, Development and Engineering Center. For this study, four male volunteers were scanned in a number of different positions, producing almost 30 datasets for analysis. The original mesh resolution is 1mm.
The coarse meshes we obtained using
i. edge decimation in MeshLab and further export to MATLAB in *.ply format;
ii. selective mesh refinement (edge splitting) in sensitive areas (hands and feet);
iii. surface-preserving Laplacian smoothing with Delaunay re-triangulation using the excellent script MyRobustCrust.m written by Dr. Luigi Giaccari.
Mesh quality is defined as the minimum triangle quality in the mesh. The triangle quality is the ratio of inradius to circumradius times two. The mesh quality of coarse meshes range from 0.32 to 0.54.
The meshes could be used within MATLAB environment or exported to Ansoft/ANSYS HFSS, Octave, etc.
