Found the problem with one case: Mathematica was occasionally writing numbers with embedded newlines, which confused the software. It's not fixed in the new release, but you can grab some files from our anonymous FTP directory: priv/slevy/math2oogl (Iris binary) priv/slevy/math2oogl.c (source for the same) For the second case -- the vector field plus what seem to be a collection of flow lines -- I think there may be nothing wrong, except that the interesting parts are hard to see. Running your example code shows a long narrow spike in the geomview window. When I turn normalization off (put the cursor in a graphics window and type N, or select None on the Obscure panel), the inner part of the spike becomes visible -- showing the collection of arrows and curves. The only problem seems to be that the extreme ends of some of the curves are very far away, so when geomview tries to display the entire scene, the interesting part is very small. When normalization is off, you see by default a region of about unit size around the origin, and can scale the object or fly the camera around to adjust the view. Stuart
