Hi Steven, I took a look at Wavefront object files and agree that it might be pretty easy to output Chimera meshes in that format. We don't currently have any way to output an entire Chimera scene in a portable format. The "Export surfaces as VRML" Chimera tool only works for volume isosurfaces. Is this the only kind of Chimera model you need to export? Can you send me the traceback you get when trying to export a large surface in VRML format? Does it work for a small surface? I can probably improve that code to work with large surfaces if I know the type of error you are getting. The "stereo" camera mode is for use with LCD shutter glasses. It requires starting chimera with a "--stereo" command-line option. This is described in the Chimera manual. It is not useful for saving images, since the display flickers between left and right eye images at a high frame rate. Before we try producing some Wavefront OBJ output it would be useful to get an example from you describing what you are doing. You can send that directly to me if you do not want those details on the mailing list. Tom
