The Cleaver Library is based on the 'Lattice Cleaving' algorithm: Bronson J., Levine, J., Whitaker R., "Lattice Cleaving: Conforming Tetrahedral Meshes of Multimaterial Domains with Bounded Quality". Proceedings of the 21st International Meshing Roundtable (San Jose, CA, Oct 7-10, 2012) The method is theoretically guaranteed to produce valid meshes with bounded dihedral angles, while still conforming to multimaterial material surfaces. Empirically these bounds have been shown to be significant

PSYS is a particle-based meshing algorithm for generating adaptive triangular surface and tetrahedral volume meshes from CAD models. A hierarchical sampling scheme places particles on features in order of increasing dimensionality. These particles reach a good distribution by minimizing an energy computed in 3D world space, with movements occurring in the parametric space of each surface patch. Rather than using a pre-computed measure of feature size, our system automatically adapts to both curvature as well as a notion of topological separation. It also enforces a measure of smoothness on these constraints to construct a sizing field that acts as a proxy to piecewise-smooth feature size.

 

OptikPack is an image processing tool I wrote in the Spring of 2010 for Dr. Guido Gerig's advanced Imaging Processing course. It includes a variety of image processing tools including: anisotropic diffusion, harmonic shape analysis, image segmentation through normalized graph cuts, scale-space object selection, and smart selection using deformable contours. It is implemented in C++, using Qt for the GUI, and VISPack for the image handling. The software has built successfully on OpenSUSE, Ubuntu, and Windows 7.
