I've gotten over 30 requests for the FC clipper, so a post is in order. I've never posted 27k of source to usenet: must the file be compressed somehow before posting? If so, let me know how and what to do and where (alt.sources?). John

I have sent the source for the FC clipper to comp.sources.misc. It's moderated, so the file will go to the moderator first. Fifty or so have requested a copy, so try to get it from comp.sources.misc. If you can't get it there (should be there RSN), I mail you a copy directly. The file is 30825 bytes. I've also written the Sutherland-Hodgman polygon clipper in Modula-2 and also Assembly. Why not C? Well, when I code in C, I write all of the time critical code in assembly and link it all together. The Modula-2 compiler didn't have a link compatible format, so no assembly. Converting from Modula-2 to C is easy, as Modula-2 looks just like Pascal (it's Pascal's successor). The SH polygon clipper is much shorter than FC. It's a fairly general clipper, and the fastest method I know of. Again, those interested, let me know. Also, if faster methods exist, please fill me in. John
