This reverts commit b36b33f716.
See #316: Caused issues with sky becoming black in dense fog.
Also: when the fog issue is solved, we could configure the constant
(black) clear color once only (during init), no need to do it in every
loop. Also, entire "if (skyblend) { ... } else {..}" was redundant,
since "if" and "else" clauses were all identical - and the "clearColor"
variables were unused. => Once the fog issue is solved, we can easily
improve the clearColor configuration here.
Panning feature looked broken to some users since auto-center is enabled
by default which blocks panning. center-on-aircraft is now disabled
automatically when view is panned.
This class and their source files visual_enviro.[h|c]xx were
unused since OSG transition. It's only functionality was to
keep a variable for the enable-state of rendering of precipitation.
This has now been moved to SGPrecipitation.
This patch also removes all references to this class and
visual_enviro.hxx. Wxradar needs a new implementation for cloud
echoes which probably should be part of fgclouds.

coordinated with and approved by Andy.
The lattice(x,y) arguments were being "WRAP()'d" but the WRAP() function
didn't make sense. Instead it was forcing the value to zero if it was
greater than the wrap limit. This was creating large areas of constant
values in the perlin noise maps which resulted in a "constant" turbulence
vector over time -- which is just weird.
Andy couldn't see any reason why the values should be wrapped and couldn't
remember any reason why the WRAP() function was set up like it was.
Andy wanted me to make sure and mention that he was INSANE when he wrote that
code (but now he's sane ... err, mostly.)
New module contributed: AV400WSim.
Supports communication with external (aka real) Garmin 400/500 WAAS flight
sim units. Includes changes to options.cxx and fg_io.cxx to support
invoking and configuring the new module.
* Update AI aircraft object based on user position.
* Process flightplan
* Don't try to update the radar information for AIAircraft that don't have a valid manager pointer
New "auto-position" switch to always use closest tower for tower-view.
Exposes new "/sim/airport/closest-airport-id" property.
Display closest airport on groundradar by default.
The internal solver of YASim which computes drag and lift
coefficients now actually uses the values configured in
the XML input file for approach fuel, cruise fuel and cruise
glide angle.
fgpanel is basically the stripped down 2D-Panel code from
FlightGear. It is designed as a standalone lightweight panel
rendering engine to draw 2d panels on a lowcost computer/graphic card
without 3d acceleration at reasonablel framerates.
Patches for inclusion into the build system will follow.
* Allow position and intentions to be monitored and updated by the Startup controller
* Added a "parent" pointer to the startup controller to allow communication with the groundnetwork.
* Implemented a render() function for the Startup controller
* Renamed "FGGroundNetwork::getRenderNode() to FGGroundnetwork::render()
- Fixed a bug in AI aircraft ground steering code: When aircraft were not moving, the value of headingchangeRate kept increasing to insane levels. Although this was clamped to a maximum of 30 degrees per second, the initial rate could still push the aircraft in the wrong direction. In practice, this bug would be visible when an AI aicraft would be pushed back, when it tended to veer to the right.
- Make sure that the aircraft slows down well ahead of the pushback point. This change ensures that the AC will actually reach the pushback point. It also ensures a slightly tighter steering range.
- AI ground steering rate is tuned to 30 degrees per second at a nominal taxispeed of 15. I now modulate the heading adjustment rate by manipulating the adjustment using a non-linear function (the sqrt). This allows for a slightly tighter turn radius at speeds < 15 and slightly looser turns at speeds > 15.
- The AI Flightplan generation code can return false. This can be used to determine whether any additional AI aircraft may be created. Currently, the function returns false when no more parkings are available. This should limit the build-up of huge AIAircraft tower stacks.
- The ground network can now graphically display all aircraft actitivy on the ground network by using a virtual marker system.
