Attached are patches to Terragear to enable it to compile out of the box on
Cygwin (once all the relavent libraries have been compiled). Specifically
they fix a conflict with another version of min/max somewhere on the
system.
but because of the use of default arguments, the compiler wasn't flagging
this as an error. This caused a) much stupidity and b) additional stupidity.
I also found a case where I passed in a length and width extention parameters
but, used the length parameter twice ignoring the width parameter. This
yields much more sensible and expected results when building the grass buffer
zone around a runway.
intermediate mode. The goal then is that these elevations would be
preserved throughout the tile construction process and the surrounding
geometry would fill in without gaps. This has potential applications for
airports and runways of course as well as roads, rivers, streams, railroads,
or any other object where we might want to control the final elevation in
advance.
position.
Terrasync runs as a separate process and accepts the --atlas=port format.
The fgfs output tells the terrasync util where FlightGear is currently flying.
Terrasync will then issue the appropriate commands to rsync the surrounding
areas to your local scenery directory.
As you fly, terrasync will periodically refresh and pull any new scenery tiles
in the vicinity.
This also works if the scenery on the scenery server is update. Rsync will
pull any missing files, or any updated files.
There is a chicken/egg problem when you first start up in a brand new area.
FlightGear is expecting the scenery to be there *now* but it hasn't been
fetched yet. I suppose without making a more complex protocol, the user
will need to be aware of this. The user could restart flightgear after the
initial rsync completes, and then after that everything should be good,
assuming the user has the necessary bandwidth to keep up with flight speeds.
Final notes:
At the moment Alex Perry has a partial rsync server, but I don't know it's
status. I hope to have a full server up and running at some point soon.
Currently the terragear utility just echos the commands it would run to
rsync the data, it doesn't actually run the commands. This is a work in
progress.
equal to the elevation of the highest light.
Approach lighting systems don't rise and fall with the prevailing terrain.
This prevents portions of the approach lighting system from dipping below
ground level in cases where the surrounding terrain is simplified and doesn't
perfectly match the DEM data.
confused by the alphabet soup.
- Forgot to impliment the SALS(F) version of SALS approach configuration.
- Was generating SSALS when the system was requesting SALSF.
it involved creating a 2d runway object of the right size, rotating it and then
trying to back solve for the actual lon/lat. This and a few other problems was
causing problems with subsequent texture coordinate calcs for the runway
surface textures. It also could have contributed to runways/lighting being
slightly misaligned with the ILS's. Then lots of minor cascading changes as a
result.
