[Flightgear-devel] new utility
This weekend I hacked together a little utility that might be interesting to some people. I called it photomodel and it's in FlightGear/src/utils/Modeller/ This is a command line utiltity that takes the name of an aerial photo texture, along with the lon/lat coordinates of the corners of the image (or the max/min lon/lat if the image is aligned along strait lon/lat edges). It then spits out a .ac file of the correct size in meters to cover your area. It tells you where to copy the file, and gives you a line to add to your .stg file (and tells you which one to add it to.) Special thanks to Syd Adams who whipped up a .ac template for me to work from. If you have access to some aerial imagery, you can use this utility to quickly spiff up a local flying area. Please note, I'm not saying you couldn't do a screen grab out of google maps or some other online mapping service to get some quick aerial imagery, but if you do anything like that, please don't distribute the results without getting explicit permission from the owner of the imagery, and please don't tell me about it. :-) Note that this utility does have many limitation at the moment ... it only spits out one square for one texture per model. The output model is flat, so you have to manually figure out an altitude that floats it a meter or two above the default terrain. It's not a perfect solution, but might be useful for some situations. I have found it handy to spiff up my local R/C flying site scenery for replaying flights in my instrumented R/C airplane: http://youtube.com/watch?v=MTkJYaiVxtA All those nice mowed fields around our airstrip have been planted with corn this year and it's now about 8' high ... sob ... :-( Regards, Curt. -- Curtis Olson - University of Minnesota - FlightGear Project http://baron.flightgear.org/~curt/ http://www.humanfirst.umn.edu/ http://www.flightgear.org Unique text: 2f585eeea02e2c79d7b1d8c4963bae2d - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Oh, yes AnMaster, i am pretty sure it could be used for mountains, look at that specific model Tour du Ventoux ( which is close to my home :) ) http://fgfsdb.stockill.org/modeledit.php?id=317 I have redrawn a 3D .ac model which include the shape of the top, with road it comes over the existing scenery. The work was not easy. I guess that with the Curt's tool it would have been easier Cheers -- Gérard - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
