Chris,
I think that you misunderstand what I am looking for.
I can already export a color VRML file of the FEA result using only one
fringe display setting.
Let's say I wish to show how a model deforms under load while also showing
the developing stresses in color gradients. The VRML file that I can export
will only be a "snapshot" of the model at some point in the load/deformation
range that I choose.
What I would like to create is a dynamic model display that perhaps combines
a series of these VRML "Snapshot" files so that I can not only rotate the
model, but also cycle it through its load/deformation range (slide-bar
control of load/stress).
I can also currently record an MPG file of the process, but it cannot be
paused and rotated to give a different view.
I can do this in my FEA modeler software but it's not portable because I
only have a limited number of licenses and systems capable of running the
code.

In VRML 2.0 model color is applied per/vertex much the same way as
OpenGL primitives. This of course allows real time manipulation with
multiple colors on your model that is much faster than say texture mapping.
Even though this standard has been around since 1997 I believe there are
only two or three viewers that support full VRML 2.0 including the colors.
I'm not sure how many other software vendors are taking advantage of this
but the standards are in place.
