Archive-name: object-archive-server/28-Jun-90 Original-posting-by: allen@basalt.uucp (Allen Akin) Original-subject: Re: Call for any and all 3-d object databases Archive-site: gatekeeper.dec.com [16.1.0.2] Archive-directory: pub/DEC Reposted-by: emv@math.lsa.umich.edu (Edward Vielmetti) Here's the scoop on Digital's public 3D object database: As a service to the graphics community, Digital Equipment Corporation has donated disk space and established an archive server to maintain a library of (somewhat) interesting objects. The objects collected are in OFF format. Documentation on OFF, a library of useful OFF routines, and one or two useful OFF utilities are also available through this archive server. The archive server lets you obtain ASCII files across the network simply by sending electronic mail. To obtain help about using this service, send a message with a "Subject:" line containing only the word "help" and a null message body to: object-archive-server@decwrl.dec.com To get an index of all that is available through this server, use a subject line of "send index" instead of "help". To get a list of objects that are available use a subject line of "send index objects" and a null message body. In order to save disk space and transmission time, the more lengthy files available through this archive are compressed using the UNIX "compress" utility and then uuencoded so that they may be sent as ASCII files. For those of you who don't have access to these utilities, buddy up to someone who does. As with other archive servers, it is only possible to get small portions of the database at a time. Small requests have priority over large ones. If you have ftp access, you can copy all of the objects and OFF programs from the file ~pub/DEC/off.tar.Z on the machine gatekeeper.dec.com. Please respect the copyright notices attached to the objects in the .off header files. The original author usually worked pretty hard to create the model, and deserves some credit when it is displayed. If anyone out there knows something about any of the objects I've left uncredited, please let me know so that I can include the appropriate credits. We'd *LOVE* to add to this collection of useful programs and objects. If you'd like to submit an object, an OFF program, or an OFF converter of some type for inclusion in the archive, send mail to: object-archive-submit@decwrl.dec.com We cannot guarantee anything about when submissions will be made available as part of the object archive, since maintaining the archive is an after-hours activity. We can only promise that an interesting or useful object that is already in OFF format will make it into the archive more quickly than one that has to be converted from another format and then tested. To report problems with the archive server, send mail to: object-archive-manager@decwrl.dec.com Randi J. Rost Workstations Advanced Technology Development Digital Equipment Corporation

PLEASE!! if you have anything > please send it, along with a description of the object format. > You will receive mention in the acknowledgements whether or not > I ever use your contribution. > There is about 20 NFF files available by ftp on irisa.irisa.fr (131.254.2.3), directory NFF. You'll find in the same directory too : -a description of the NFF file format by Erich Haines. -the haines utilities (haines.tar.Z): somes programs that built fractals NFF scenes with lots of polygons. - some others utilities (utils.tar.Z) On the same site, in the directory iPSC2/VM_pRAY you'll find the parallel ray-tracer of Didier Badouel (email : Didier.Badouel.irisa.fr) for an iPSC2 machine. I try to collect, convert to NFF and made available by ftp every 3-d object databases I can find. So don't hesitate to send me any 3-d objects you have. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Thierry LECONTE | , ,--- ,--- | | INRIA/IRISA | / / /--- | | Campus de Beaulieu | (___ (___ (___ | | 35042 RENNES CEDEX | | | FRANCE | GOTHIC project (INRIA/BULL) | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Tel: 99 36 20 00 e-mail: Thierry.Leconte@irisa.fr | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
