Instrumentation and systems are now configureable from xml files. The two
generic configurations generic-systems.xml and generic-instrumentation.xml
configures the systems and instrumentation as it was hardcoded. You can
override the generic configurations in a similar way as you override the
autopilot configuration.
Fix the leg distance calculation to display nautical miles instead of meters.
It turns out that Simgear already has a range normalize function, so I use
that one instead.
I've added a vertical navigation capability to the GPS module. One can input
two waypoints, wp[0] and wp[1], with altitude. If the altitudes differ, then
the altitude deviation from a "straigth" line from wp[0] to wp[1] is
calculated. The true course and course deviation from wp[0] to wp[1] is also
calculated. All this can be found in the wp subdir where one also finds the
wp[0] and wp[1] subdirs.
All this has to be done through the property browser. Maybe I should make a
gui window for the GPS!
I've added a tracking bug to the gps. This is of course very similar to a
heading bug for a DG. I don't know if this is the common name, but I feel
that for a gps the name tracking bug is more accurate than heading bug. A
true bug error and a magnetic bug error is calculated and shifted into the
-180 to 180 range so that they can be used by autopilots.
I've also fixed a property name that crept in when I had to change back to
indicated-***. Back then I accidentally changed the desired course name to
"indicated-course". The property that is supposed to be the input for the
desired course should naturally be named something like "desired-course", and
definitely _not_ "indicated-course". If this name change breaks anything it
should be fixed in the other end.
I've also commented out a lot of #includes that I don't think is needed. I'm
on Suse 9.0 now, and it builds fine here, but this might be a problem for
different platforms I guess we have to cross our fingers.
I've done som more work on the gps instrument.
- You can now input airport-, nav- or fix-ID to select a waypoint.
- You have to specify either "airport", "nav" or "fix" in the waypoint-type
property (some fixes and navs have identical IDs).
- Formatted the time to waypoint output.
- Cleaned up and changed some propery names (wp-heading -> wp-bearing).
- I've also added a name member to the FGNav class so that the gps instrument
can get the name of the nav.
- Changed the airport name parsing in simple.cxx.
scene management code and organizing it within simgear. My strategy is
to identify the code I want to move, and break it's direct flightgear
dependencies. Then it will be free to move over into the simgear package.
- Moved some property specific code into simgear/props/
- Split out the condition code from fgfs/src/Main/fg_props and put it
in it's own source file in simgear/props/
- Created a scene subdirectory for scenery, model, and material property
related code.
- Moved location.[ch]xx into simgear/scene/model/
- The location and condition code had dependencies on flightgear's global
state (all the globals-> stuff, the flightgear property tree, etc.) SimGear
code can't depend on it so that data has to be passed as parameters to the
functions/methods/constructors.
- This need to pass data as function parameters had a dramatic cascading
effect throughout the FlightGear code.
