- Hello everyone.
-
- I just uploaded a new version of Zed3D. Zed3D is a handy tutorial and
- reference for real-time 3D graphics. It includes most proofs as well as
- some pseudocode. Zed3D cover several topics, among which are:
- texture mapping, gouraud shading, z-buffering, depth-field rendering,
- bitmap scaling, rendering a polygon, reducing a polygon to a mesh of
- triangles, automatically generating normals for polyhedras and more.
-
- It also now includes an example 3d graphics engine (basic), with
- source code.
-
- WHAT'S NEW OR A RECENT ADDITION:
- A total rewrite of the document. I split everything into the proper
- chapters, and made a table of contents. The file formats now supported
- are Word 2 and PostScript.
-
- Here follows the "Getting Zed3D and reading it on my system" FAQ.
-
- ==============================================================================
- HOW DO I GET IT?
-
- Through FTP.
-
- As soon as Jouni moves it to its home directory, the file will be available
- as:
-
- [x2ftp.oulu.fi:/pub/msdos/programming/docs/zed3d080.zip]
-
- Current version is 0.80 (that's why the file is named thus).
-
- If it's not there right at first, give Jouni some more time to move it.
-
- Complaints/comments about the above FTP service (and only that FTP service)
- should go to ftpadm@x2ftp.oulu.fi.
-
- The document is also available through WWW. The URL page is:
- http://www.cs.colostate.edu/~hadjiyia/3d.html
-
- That page is maintened not by me, but by Mr Simos Hadjiyiannis.
- If you are having any problems with that page, it would be better
- that you contact Mr Hadjiyiannis instead of me, as I do not have the
- ability to make modifications directly to that WWW page. I cannot guarantee
- that the WWW page is the latest version of the document. If it is not the
- latest version, you should be able to get the latest one from the FTP site
- above.
-
- Mr Hadjiyiannis can be reached at the following e-mail address:
- hadjiyia@cs.colostate.edu.
-
-
-
-
- FTP SAYS "UNKNOWN HOST" OR SOMETHING OF THE LIKE, WHAT DO I DO?
-
- The host is x2ftp.oulu.fi (make sure you type x2ftp, not ftp). It can also be
- reached as teeri.oulu.fi. If all else fails, the IP address is
- 130.231.48.141. If you enter that instead of a server name, it will (should)
- connect you to x2ftp.
-
-
-
- I DON'T HAVE FTP ACCESS, WHAT DO I DO?
-
- For those of you without FTP access, there are a number of mail services
- you can use to do any kind of FTP operations. You could try mailing to these
- addresses:
- ftpmail@inet-gw-2.pa.dec.com
- bitftp@pucc@princeton.edu
-
- The body of the letter should be "help", it will then explain how it works.
- Another one that I heard of, but I think it works differently is:
- ftpmail@decwrl.dec.com
-
- If you have comments or corrections to make to the above FTP mail services,
- mail me.
-
-
-
- THE FILE I GOT WAS GARBLED, WHAT HAPPENED?
-
- If it's only the .PS file that is garbled, you have a copy of version 0.41
- (it was unfortunately garbled at that time).
-
- If you are getting errors as you decompress the files, you might be using
- the wrong decompressing utility. The archive is compressed using PKZIP version
- 2.04g.
-
-
-
- I AM ON UNIX, I DECOMPRESSED IT AND ONLY GOT A SINGLE UNREADABLE FILE,
- WHAT IS WRONG?
-
- You are probably using "gunzip" instead of "unzip". Here, I will quote Jeff
- Epler:
-
- ----8<-----cut here--------------------------------------------------------
- I don't know about anything else in this message, but it's possible
- that this person used 'gunzip' on a pkzip archive -- Gunzip minimally
- understands .zip files with deflated entries, but only extracts the
- first file. They should use 'unzip' from info-zip, source from
- ftp.uu.net:/pub/archiving/zip/unzip512.tar.Z , and it'll take some
- knowledge of unix to compile and install it.
- ----8<-----cut here--------------------------------------------------------
-
-
- I WOULD LIKE TO GET AN EXECUTABLE VERSION OF UNZIP, HOW DO I DO THAT?
-
- I don't know. Get the C source (last question) and compile it or find
- someone to compile it for you.
-
-
- I CANNOT READ ANY OF THE FILE FORMATS INCLUDED IN YOUR PACKAGE, COULDN'T
- YOU PUT SOME OTHER FORMAT IN THERE?
-
- If I find a way of making a PS, HTML or some other format file, I will.
- Otherwise, until then, if you can't give me specific instructions, don't
- ask for some specific file format, because I won't be able to do so.
-
-
- WHAT ABOUT US ASCII-ONLY GUYS?
-
- I'm working on that - dunno if I will do it. In the mean time, you can
- always try to examine the .PS file. To do that, you will need either a
- PostScript printer or a .PS file viewer. There exists a free .PS file
- viewer package thing called GhostView and GhostScript, made by the
- fine guys at the Free Software Foundation or GNU or whatever. The viewer
- has been compiled for a number of different platforms, both unix and
- others. SimTel sites should carry it in some form or other. One such
- site is the ftp site oak.oakland.edu. Note that if you use that program,
- you are totally, completely on your own, I will not be able to help,
- refund, pay indemnities or whatever in any way. If you have any questions
- about these programs, contact the FSF.
