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.
