Larry,
Yes I misunderstood, but no worries because it is still possible to do
what you want in VRML through the use of texture mapping. Essentially you
would need to obtain texture maps that represent your fringe displays at
some determined interval of load, then apply them to the model using the
viewers controls or control that is customed programmed. This will of course
be slower than vertex based colors and you could pay a large penalty
depending on the size model and size texture.
There may be something like this already available for consumption in
popular viewers, check out www.vrml.org www.cai.com/cosmo/ . If not then
the viewers as well as the file format is extremely extensible. Someone with
experience can likely customize this for you at a minimal cost / time to
your company. If you wanted to you could do this yourself, some tools to
look at are the SGI cosmo create suite http://www.sgi.com/software/cosmo/.
