How to convert *.txt files to *.obj files?

[stampede]

@ChrisW67: I think the mentioned .txt files are in fact .obj files, which contains description of 3d meshes ( list of vertices, faces and edges, vertex groups info and material references, all in human-readable text format ), and babygal wants to convert those text files (.obj) to some kind of binary format, which is suitable for loading in her application.
Anyway I think it could be good to ask on 3d max, blender, ZBrush, Ogre or something-related-to-3d community forum, it's more probable that you'll find help with mesh files format conversions there.
Another thing is that writing an .obj parser is quite easy task, but if you don't feel like doing it, try asking on 3d-related community forum.

You could also look at MeshLab because they seem to handle a lot of file formats of this type and the source is available.
