I am looking for information on the origins of the .obj 3D object format. By the time I had arrived at Robert Abel & Associates in 1980 or so, it was already in use for our vector production system which ran on E&S Picture System 2s.
My question is where it came from originally. I had thought that it was indigenous to Abel's, but several people have told me that it wasn't and that it originated with Evans & Sutherland. This makes sense but I have not been able to confirm it.
The reason I am so interested is because I think I was instrumental in extending this horrible format into raster graphics. Its a long story and I want to get all my facts straight first.
If you know, or know someone at E&S I can talk to, leave a comment here or email me. Thanks.
