%description
Iso2Mesh is a MATLAB/Octave-based mesh generation toolbox,
designed for easy creation of high quality surface and
tetrahedral meshes from 3D volumetric images. It contains
a rich set of mesh processing scripts/programs, working
either independently or interacting with external free
meshing utilities. Iso2Mesh toolbox can directly convert
a 3D image stack, including binary, segmented or gray-scale
images such as MRI or CT scans, into quality volumetric
meshes. This makes it particularly suitable for multi-modality
medical imaging data analysis and multi-physics modeling.
Iso2Mesh is cross-platform and is compatible with both MATLAB
and GNU Octave.
