During the time I have been reading this group I have seen many references to
GIF, TIFF, IFF, FBM and so on, but I have not seen mention of any standard 3D
object information files.
My question is, are there any (reasonably) standard file formats for 3D objects
out there, and if so, what are there specifications. I am writing a program to
manipulate 3D objects, and I would like the files I produce to be compatible
with some standard, for easier interchange.
If I receive enough mail on the subject, I shall summarize.

No problem!). The specification is 500 pages long, but fortunately if all you want to do is create IGES files (as opposed to read them in general and display them), you only have to read a small piece of it. Try calling information in Washington D.C. If you have ftp access, albanycs.albany.edu has a few 3-d objects and a 3d specification, but I'm not sure how common that specification is. ---------------------------------------------------------------------- Brian Smokefoot "... never knowing I could shape my life brian@hpfcbdr.HP.COM like the artist paints his dreams on a canvas." - Minor Detail

Are there any agreed upon file formats for 3D graphics, eg. representation of
lines, surfaces, objects etc etc. If so, what are they, and where can I
obtain documentation on them? Reply either here or by e-mail.
Thanks,
Andy.

Reply either here or by e-mail. A few months ago I wrote a summary of some CAD interchange file formats. There is a copy of that summary that can be FTPed from ccu1.aukuni.ac.nz (130.216.1.5) it is in the /mac/architec directory. It is a MS WORD 4 document, if you don't have access to a Mac and Word let me know and I will arrange something you can handle? RTF?
