LBIE-Mesher (Level Set Boundary Interior and Exterior Mesher) can extract adaptive and quality 2D (triangular or quadrilateral) meshes over isosurfaces and 3D (tetrahedral or hexahedral) meshes with isosurfaces as boundary surfaces directly from volumetric imaging data. LBIE-Mesher can generate 3D meshes for the volume interior to an isosurface, the volume exterior to an isosurface, or an interval volume between two isosurfaces.

The main algorithms to generate triangular, quadrilateral, tetrahedral and hexahedral meshes directly from volumetric data are described in our meshing papers [1-4]. Please contact Jessica Zhang (jessicaz@andrew.cmu.edu) for detailed information.
