Yes, that's the default. > Thanks! I may try this and see the differences.

In general, we haven't provided that functionality. The "GIstViewer2D" has a "plotMesh" method, which I'm sure works, but that is the only viewer that has a method for this. Actually, Mayavi 1 has a "display wire mesh" option, so you might want to try that. As far as exporting to different file formats (other than the tsv viewer), we don't support any format in particular, but python string formatting and io makes it fairly easy to write one for whatever mesh displayer format you prefer. -- Daniel Wheeler
