Mon Oct 28 09:45:06 PST 1996 - various enhancements to produce more compact octmesh files. specifically, when the input data consists of scalar data, we will convert it to unsigned byte format, thus achieving some space savings.
we will try really hard to write an octmesh object which conforms to the following attributes: 1. floating point 3space location data. 2(a). byte, scalar color information 2(b). rgba colormap (NOT a vis colormap) 3. floating point 3dim "normals" which represent gradient in the original floating point input scalar data.
only if the input data contains 4-component (or 3-component) color information at each vertex will this format of data be written.
Sun Jan 19 1997 : Steve K new geometry services has no support for colormap : octmesh will contain float rgba colors.
