Re: [Flightgear-devel] City signs
How did you made that ? Is it a scenari object inserted in the .stg or a run time generated poly from a text string ? I made a simple 1000m long rectangle to form the sign. The texture is a 256x256 rgb that can contain about 8 city names (depending on font size, of course). I put it in the .stg file: OBJECT_SHARED Scenery/Objects/e000n40/e007n49/sembach.ac7.855 49.513 500.0 0.0 It hovers about 200m over the terrain. This one was done by hand, no auto-generation involved.

Also, I wonder if the HUD could generate and place text strings instead? Here are possibilities: 1) Allow each .stg file to have one 256x256 texture, hand made, containing the names of the biggest 8 (or 16, or whatever) towns. The signs and their associated .xml files would also be individual and hand made. 2) Jon's hollywood sign method, where the signs are autogenerated using individual letters. 3) Make a text animation (I'm guessing this doesn't exist yet?). 4) Have the HUD autogenerate tags that would appear superimposed over the appropriate coordinates. Of these, number 1 is available now, in concept, although people will have to make the signs. I'm willing to make a set for SFO.

The HUD uses the plib font system. This is simply a 256x256 texture with all the letters placed in rows/columns. With a little investigation, it should be pretty simple to build an object and texture it with the appropriate bits from the font texture, I wouldn't be surprised if plib would provide the necessary capability.

Dave, Interesting you should mention that. This would be great for those of us who fly fgfs using VFR. Have you seen my mail from a while back http://mail.flightgear.org/pipermail/flightgear-devel/2003-February/015331.html? If I remember correctly this MSFS add-on allows you to do something similar. As I'm very visually challenged, a sign in the air over an airport saying KJFK 2.5 miles or some such would be a big help finding my way around. Identifying particular buildings in the air would be nice too. (Golden Gate bridge, Washington Monument, landmarks like large cemetaries and parks). I'd love to work on this eventually but that'll probably never happen at the rate I'm going. 8-( Yes, a sign pointing the way to Mount Ranier would definitely help me also. I know it's big, but somehow I can't seem to find it with my eyes. 8-) Perhaps something similar could be used to mark restricted airspace. Something especially useful would be signs for those features found on vfr charts. For example, the San Antonio sectional has: A border with Mexico Various Defence areas River Names Campgrounds Outdoor theaters, bridges, railroads, mountains and so forth. Lots of useful information for finding where you are in a sectional chart or other map/chart. Perhaps the signs can be turned on/off with various levels as the log messages are? OBJECT_SHARED Scenery/Objects/e000n40/e007n49/sembach.ac7.855 49.513 500.0 0.0 It hovers about 200m over the terrain. Perhaps showing the height of the tallest elevation on the sign would also be a help? (height of mountains, buildings, statues, etc). Just some ideas. Very, very interesting, thanks! I am still wondering if there is a free database anywhere of buildings and locations. Anyone heard of any? Would using the information off of a chart or other online data for example, Sierra de los Pilares on the San Antonio sectional has a spot elevation of 4816. Could that be used or would it need to be based on other sources. In high school, we were always told that if you found the same information in more than two sources it's common knowledge and doesn't need to be attributed. Is that also true of maps and charts? If so, how could one document where the information being put on signs is coming from? Is US government information on public charts available for use? How is this 'common knowledge' and US government sources impacted by GPL and other licenses? Sorry for all the questions. Thanks! Ima BTW, I am in the process of switching isps and hope this msg is coming through without html.

Dave, Yes, that's invaluable. You're fast! 8-) That's EXACTLY what I was looking for! Now if it only said, Alcatraz 2.5 miles @ 255 degrees. Oh, but I can dream can't I? 8-) You can get prices of sectional charts here, they're about 8 dollars or so each. Here's a price list: http://naco.faa.gov/content/naco/pricelists/PriceListNACOAeroOct2004.pdf I buy them at a tiny airport about 10 miles from my house, they charge reasonable prices. All my charts are out of date (not for realworld navigation), but I will send you the San Francisco one if you email me a snail mail address. (Actually, I can't find the San Francisco one, but I have Chicago and San Antonio at hand at the moment and will look for San Francisco). The properties and keybinding idea you suggest does seem like a very good way to go. Thanks again, and please let me know if you need me to look for the SFO chart.

Melchior, That's also very nice! Either would work very well for me. Yours is very colorful! I can see the balls working also as the circles do in the msoft flightsimulator tutorial. In the tutorial, you can fly down hoops to catch the right glideslope for landing. It helps to hold my vertical descent rate (not that I've used that other simulator since starting flightgear). 8-) It would be nice if flightgear could do something similar. Maybe help for a tutorial or for new users. A new flyer could just follow the balls down to landing... Just another idea... Thanks to you and dave for your suggestions and efforts!
