February 20, 1993The files contained within this directory are many of the pieces of theFly! Demo, a landscape fly-over package designed by PCI Inc., of Ontario,Canada. They have kindly allowed us to upload their demo software to bothof our archive sites, so people could peruse.The software Fly! is software that allows the user to fly over terraindata, on any UNIX computer equipped with an X-windows-compatible display.Supported machines include AUX, DEC, DG, HP, IBM, IG, KP, SCO, SGI, andSUN. We currently only have installed the software for DEC, HP, IBM, SGI,and SUN, in the assumption that relatively few others will be usingUnix-based machines that aren't in this set. If you are interested intrying 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 getyou a copy of the software that works on your machine.The folks at PCI have plans to develop Fly! into a full virtual realityapplication. Future enhancements to the product include support for theSpaceball, 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 (whichcan be changed easily). It will show the data in black and white, color,false color, or 3D via anaglyph (red/blue) glasses. Performance on themachines that I personally have tried range from about 1 to 8 frames persecond, with the average being near 5. (Tests were performed on a DEC5000, HP 9000, SGI 4-processor, and IBM RS/6000.) The demo reports that data can be read in from many file formats, includingPCIDSK, TIFF, RAW, ISTAR, and ERDAS. Rendered scenes can also be saved todisk, 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 Installation / User Guide 4761757 small.pix.Z Fly! dataset, one .pix file 1182031 tiny.pix.Z Fly! dataset, is necessaryIn 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 theword "anonymous" for your username, and enter your username@hostnameaddress for the password. Then type "cd" followed by the appropriatedirectory to gain access to the archive.Enter "cd fly" to go into the Fly! Demo archive. The files contained inthis directory are all compressed, so you will need to now type the word"binary", so that the ftp program will properly download the software inthe correct format. Choose the software appropriate for your system, and then retrieve it byentering the command "get filename", where "filename" is replaced byfly***.tar.Z, dependent on your system. After this is completed (it willtake 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 theftp program.To uncompress and unarchive the software on your home system, execute thefollowing 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 intoyour 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 thecommand "lpr -Pprinter flydemo.ps", where "printer" is aPostScript-compatible printing device (alternately, you could display themanual on your monitor using one of the many PostScript viewers freelyavailable, 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, small.pix dataset loaded,displayed with false colors.If your display variable is set, executing any of the fly programswill bring up the software on your X-terminal. For best performance,run the Fly! Demo by itself, on the tiny dataset, with as few otherpieces of software running on the machine as possible. Also, it isbest to run the software on an X-terminal directly connected to therunning machine, so the network bottleneck isn't as bad. Lastly, theFly! 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 havequestions regarding installation, or PCI know if you'd like larger demodatasets or have questions regarding their product. ---Mark A.
