Thanks Paul,
It seems to me that I would need a similar convenience routine that
creates GL_LINE_... primitives for arbitrary geometry.
The thing is a lot of fe-models still use quads, end-users expect to see
quads for their fe-models.
In general, then, I'd advise you to stick to GL1/2 and use GL_QUADS
PrimitiveSets in Geometry-type Drawables, and GL_LINE polygon mode.
Or, knowing that all modern graphics hardware draws a quad as two
triangles, the other way to handle this would be to keep two
representations of your model, one for fill, and one for line. They
could easily share the same vertex data, so this should not consume a
substantial amount of resources.
So you have many options available to you.
