  2. Cleaver Conforming Tetrahedral Mesh Multimaterial Volume

  3. Input Representation • Two material interfaces: • Isosurface: level set of a continuous scalar function in 3D • Multi-material interfaces: • ?? • Indicator functions • One indicator function for each material • Scalar value indicates strength/contribution of material • Examples: • Distance Transforms • Partial Mixture Models

  4. Input Format Teem’s Nearly Rasterized Raw Data format (NRRD) • Seg3D Compatible • Human Readable Headers http://teem.sourceforge.net/nrrd/index.html

  5. Output Formats • Tetrahedral Meshes • TetGen format (*.node, *.ele) - ASCII • Matlab format (*.mat) - Binary • Triangle Surface Meshes • PLY format – Stanford Triangle Format - ASCII
