How do you want them labelled? I would assume for the triangles you'd like the triangle index number? That's reasonably straightforward to do (and I'll describe if you say that is in fact what you want). How would you like to see the edges labeled? That's going to be trickier, but I imagine someone out there has done this.

Hi, I have just found out about opendx, and have downloaded it and been playing with it for a couple of hours. So far, I have been quite impressed. I mainly want to plot volume data sets (tomography/CAT-type) and 3D scatter plots. However, there is an interest in plotting 3D structures constructed of triangles. In general, each triangle (and edge) should be labeled. Also, it would be nice to plot a number of vectors with respect to each edge. Is this feasible with OpenDX? In the past, people have used Matlab, which does a nice job, but is rather useless for large (read: a lot of triangles) structures. We have tried to have an OpenGL application, but gave up on the labeling step.
