Kent, You don't say what your application is, but I have a situation that may be similar. I'm running an Eulerian finite difference code where space is partitioned into regular hexahedra. Many of those cells contain multiple materials and material boundaries can only be inferred by the contents of neighboring cells. I create fields containing the relative volume (volume of material / volume of cell) of each of the materials in the calculation, a single byte value is plenty of resolution and provides some space savings. A single isosurface (normally at 0.5) of each of the fields, colored differently for each material, provides a good representation of the discontinuous regions of material concentration.
