- The files contained within this directory are many of the pieces of the
- Fly! Demo, a landscape fly-over package designed by PCI Inc., of Ontario,
- Canada. They have kindly allowed us to upload their demo software to both
- of our archive sites, so people could peruse.
-
- The software Fly! is software that allows the user to fly over terrain
- data, on any UNIX computer equipped with an X-windows-compatible display.
- Supported machines include AUX, DEC, DG, HP, IBM, IG, KP, SCO, SGI, and
- SUN. We currently only have installed the software for DEC, HP, IBM, SGI,
- and SUN, in the assumption that relatively few others will be using
- Unix-based machines that aren't in this set. If you are interested in
- trying out the demos, but do not have access to any of these machines,
- please let the folks at PCI know, and I'm sure they'll do their best to get
- you a copy of the software that works on your machine.
-
- The folks at PCI have plans to develop Fly! into a full virtual reality
- application. Future enhancements to the product include support for the
- Spaceball, Virtual Technology's Cyberglove, and the Virtual Reseach
- Flight Helmet HMD. We will of course try to get demo versions of these,
- as well. :)
-
- Fly! displays terrain data in a perspective view, by default 320x200 (which
- can be changed easily). It will show the data in black and white, color,
- false color, or 3D via anaglyph (red/blue) glasses. Performance on the
- machines that I personally have tried range from about 1 to 8 frames per
- second, with the average being near 5. (Tests were performed on a DEC
- 5000, HP 9000, SGI 4-processor, and IBM RS/6000.)
-
- The demo reports that data can be read in from many file formats, including
- PCIDSK, TIFF, RAW, ISTAR, and ERDAS. Rendered scenes can also be saved to
- disk, and fly-overs can be recorded. Many other options can be tweaked--
- see the manual for details.

- A description of the files contained here:
-
- Number of bytes Filename Description
- --------------- -------- -----------
- 1096054 flyDEC.tar.Z Fly! Demo, for DEC workstations
- 338929 flyHP.tar.Z Fly! Demo, for HP workstations
- 726302 flyIBM.tar.Z Fly! Demo, for IBM workstations
- 2011329 flySGI.tar.Z Fly! Demo, for SGI workstations
- 1071212 flySUN.tar.Z Fly! Demo, for SUN workstations
- 85399 flydemo.ps.Z Fly! Demo Installation / User Guide
- 4761757 small.pix.Z Fly! dataset, one .pix file
- 1182031 tiny.pix.Z Fly! dataset, is necessary
-
- In order to get the software, you must anonymously ftp to one of our sites:
-
- Archive Host name Directory
- ----------------------- ------------- ---------------
- sci.virtual-worlds ftp.u.washington.edu public/virtual-worlds/
- sci.virtual-worlds.apps kth.se pub/sci.virtual-worlds.apps/
-
- Type "ftp" followed by the host name from your system prompt. Type the
- word "anonymous" for your username, and enter your username@hostname
- address for the password. Then type "cd" followed by the appropriate
- directory to gain access to the archive.
-
- Enter "cd fly" to go into the Fly! Demo archive. The files contained in
- this directory are all compressed, so you will need to now type the word
- "binary", so that the ftp program will properly download the software in
- the correct format.
-
- Choose the software appropriate for your system, and then retrieve it by
- entering the command "get filename", where "filename" is replaced by
- fly***.tar.Z, dependent on your system. After this is completed (it will
- take a few moments), also execute "get flydemo.ps.Z" and "get tiny.pix.Z"
- (and/or "get small.pix.Z"), to get the manual and dataset, respectively.
-
- Now the software should be on your home system. Type "quit" to exit the
- ftp program.
-
- To uncompress and unarchive the software on your home system, execute the
- following set of commands:
-
- (From here on, I'll use a * to denote your system type.)
-
- zcat fly*.tar.Z | tar xvf -
- uncompress flydemo.ps.Z
- uncompress tiny.pix.Z
- mv tiny.pix fly*
- (Optional: uncompress small.pix.Z; mv smallpix fly*)
-
- This last step is very important-- if you don't move the tiny.pix file into
- your fly*/ directory, the software will not load up the dataset properly.
-
- Now, you're ready to roll. You can print out the manual by executing the
- command "lpr -Pprinter flydemo.ps", where "printer" is a
- PostScript-compatible printing device (alternately, you could display the
- manual on your monitor using one of the many PostScript viewers freely
- available, like ghostview.) Type "cd fly*".
-
- You should now see a number of new files. Here are there uses:
-
- File name Purpose
- ------------ -----------------------------------------------------------------
- README Usage description.
- fly Fly! Demo, no dataset loaded.
- flytiny Fly! Demo, tiny.pix dataset loaded, displayed in color.
- flytiny3d Fly! Demo, tiny.pix dataset loaded, displayed in stereo.
- flytinybw Fly! Demo, tiny.pix dataset loaded, displayed in black and white.
- flytinyfalse Fly! Demo, tiny.pix dataset loaded, displayed with false colors.
- flysmall Fly! Demo, small.pix dataset loaded, displayed in color.
- flysmall3d Fly! Demo, small.pix dataset loaded, displayed in stereo.
- flysmallbw Fly! Demo, small.pix dataset loaded,displayed in black and white.
- flysmallfalse Fly! Demo, small.pix dataset loaded,displayed with false colors.
-
-
- If your display variable is set, executing any of the fly programs
- will bring up the software on your X-terminal. For best performance,
- run the Fly! Demo by itself, on the tiny dataset, with as few other
- pieces of software running on the machine as possible. Also, it is
- best to run the software on an X-terminal directly connected to the
- running machine, so the network bottleneck isn't as bad. Lastly, the
- Fly! Demo is happiest when run under a Motif environment, i.e. mwm.
-
- We hope that you enjoy the software, please let me know if you have
- questions regarding installation, or PCI know if you'd like larger demo
- datasets or have questions regarding their product.
