Irregular2DSet makes triangles not rectangles, and Irregular3DSet
makes tetrahedra not cubes. To get a topology of cubes you must
use Gridded3DSet. However, neither Irregular3DSet nor Gridded3DSet
will make a volume rendering. For that you need a Linear3DSet. If
you have curvey cubes in your Gridded3DSet then you must resample
your Field to a Linear3DSet to get a volume rendering.
