===Image-based approach===

This approach is the more direct way as it combines the geometric detection and mesh creation stages in one process which offers a more robust and accurate result than meshing from surface data. Voxel conversion technique providing meshes with brick elements <ref>Fyhrie et al, 1993. The probability distribution of trabecular level strains for vertebral cancellous bone. Transactions of the 39th Annual Meeting of the Orthopaedic Research Society, San Francisco.</ref> and with tetrahedral elements <ref>Frey et al, 1994. Fully automatic mesh generation for 3-D domains based upon voxel sets. ''International Journal of Methods in Engineering'', 37, 2735–2753.</ref> have been proposed.

Another approach generates 3D hexahedraltetrahedral or tetrahedral elements throughout the volume of the ___domain, thus creating the mesh directly with conforming multipart surfaces. <ref>Young et al, 2008.
