1Right from the start, I've used the Xpm lib because it is very useful. 2In fact, it is so useful that I'm not eliminating it from 3Dc despite 3the fact that it is not a 'requirement' for development on X. Xpm was 4written by Arnaud Le Hors and GROUPE BULL. I haven't included any 5specific copyrights for them because you have to get libXpm to compile 63Dc anyway, so you'll get it that way. 7 8In moving from Motif to plain Xaw (or preferably Xaw3d, if you have it), 9I've imitated a lot of code from libsx by Dominic Giampoalo, who deserves a 10lot of credit for making X accessible to beginner programmers. Even if 11you're an accomplished programmer, libsx is highly cool. The only reason 12I don't use it directly is because I had already written most of the code, 13and didn't want to change too much. All my new projects will use it though. 14Also, the DrawingArea widget that he uses, written by David Nedde, is copied 15directly into 3Dc - no infringement of copyright is intended, and his copyright 16notice is preserved in DrawingA*. 17 18Finally, thanks to Michael B. Martin for providing (at least temporarily) 19a home ftp/http site for 3Dc. See 20http://mbmartin.bevc.blacksburg.va.us/~paulh/3Dc/3Dc.html 21 22
