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 tessellationallows the isosurface to evolve continuously when the
isovalue is changed continuously.
