  abstract = "Three dimensional datasets representing scalar fields
              are frequently rendered using isosurfaces. For datasets
              arranged as a cubic lattice, the marching cubes algorithm
              is the most used isosurface extraction method.
              However, the marching cubes algorithm produces
              some ambiguities which have been solved using different
              approaches that normally imply a more complex
              process. One of them is to tessellate the cubes into
              tetrahedra, and by using a similar method (marching
              tetrahedra), to build the isosurface. The main drawback
              of other tessellations is that they do not produce
              the same isosurface topologies as those generated by
              improved marching cubes algorithms. We propose an
              adaptive tessellation that, being independent of the isovalue,
              preserves the topology. Moreover the tessellation
              allows the isosurface to evolve continuously when
              the isovalue is changed continuously"
