Can anyone help me understand the models that can be used in Gem? Are there any open source freeware programs that can work with them? Thanks, Ken

Sure, what do you want to know?
GEM uses an opensource library called glm to load models. The models are the Wavefront .OBJ format which uses a plain ASCII text file to store the vertex, normal, and texture coordinate data. glm works well in GEM with two caveats that I know about:
is loaded as one display list and uploaded to the graphics hardware.
comments between blocks of data.
Both of these are being looked into.

I believe Blender will output .obj files. At some point in the near future, I hope to have GEM saving .obj files out to disk, but that won't be for some time.

probably. in the future ;-(
it is definitely a problem, to create .obj-files with open-source programs (although the format is very simple, and the parser, used by gem, is included with the glut-documentation (so it should be well known)
i remember having written scripts that use vtk to convert between different file-formats (like 3ds, vrml, dxf and obj)

I've been using wings3d. It's easy to use, not the kind of learning curve I associate with blender (which I still haven't understood). Not a lot of features, but probably just what you need to create obj's. It's only a polygon mesh modeller, no skeletons, nurbs, animations. This kind of data can't be used in gem anyway afaik.
