- Hello everyone.
-
- I just uploaded a new version of Zed3D. Zed3D is a handy
- 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, linear & affine mathematics,
- quaternions, rendering a polygon, triangulation of a polygon,
- generating correctly oriented normals for polyhedra and more.
-
- It also now includes an example 3d graphics engine (basic), with
- source code.
-
- WHAT'S NEW OR A RECENT ADDITION:
- Splines & anti-aliasing.
-
- Here follows the "Getting Zed3D and reading it on my system" FAQ.
-
- ==============================================================================
- HOW DO I GET IT?
-
- My official homepage is up since Jan 17th 1996. It should stay there until
- at least April 1997. The page is http://www.cs.mcgill.ca/~zed/. On it, you
- will find a downloadable version of Zed3D, as up to date as I can make it.
-
- Note that on that homepage, you will also find some useful links to other
- pages that might help you with the Zed3D package, such as de-zipping tools
- and PostScript viewing tools.
-
- The file is no longer officially available through FTP.
-

-
- 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.
-
- If you got it off FTP, you might have used an ASCII transfer. Make sure you
- are using a BINARY transfer mode (this can normally be specified by typing
- bin on your ftp software). If you transfered the filed through a stupid
- telnet, it might also have gotten garbled. Other intervening tools can
- also interfere. For instance, on a laptop I tried, the "rcp" program
- required a special option for "binary".
-
-
-
- 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.

-
-
- I WOULD LIKE TO GET AN EXECUTABLE VERSION OF UNZIP, HOW DO I DO THAT?
-
- Binaries for various platforms are available at
-
- http://quest.jpl.nasa.gov/Info-ZIP/UnZip.html
-
-
-
-
- I CANNOT READ ANY OF THE FILE FORMATS INCLUDED IN YOUR PACKAGE, COULDN'T
- YOU PUT SOME OTHER FORMAT IN THERE?
-
- Tough luck. :)
-
- Really, you should be able to find GhostView or GhostScript somewhere. See
- the next question.
-
-
-
-
- WHAT VIEWERS CAN I USE TO VIEW ZED3D?
-
- If you have access to FTP and you are using MS Windows, you can
- get Microsoft's Word file viewing tools:
-
- ftp.microsoft.com/softlib/mslfiles/wordvu.exe (for Windows 3.1 or later)
- ftp.microsoft.com/softlib/mslfiles/wd95view.exe (for Win 95)
- ftp.microsoft.com/softlib/mslfiles/wd95view.txt (I dunno what that is)
- ftp.microsoft.com/softlib/mslfiles/wd1153.exe (White paper, whatever
- that is)
-
- Of all of these, I only checked out Wordvu on Windows 3.1, which worked
- fine for me.
-
- You can also get GhostView + GhostScript for various platforms. Try this
- web page:
-
- http://www.cs.wisc.edu/~ghost/index.html
-

-
- I DON'T HAVE ACCESS TO FTP!
-
- 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
-
-
-
-
- I DON'T HAVE ACCESS TO THE INTERNET!
- I DON'T HAVE ACCESS TO THE WEB!
- I DON'T HAVE ACCESS TO MAIL!
-
- Tough luck.
