|
|
* Tweaks to build with newest gcc under Irix contributed by Erik Hofman.
|
|
|
|
* Clean out a pile of old junk in the material manager library from the
|
|
pre-ssg days, and majorly overhauled it.
|
|
* Complete reengineering of the panel code in preparation for moving the
|
|
configuration out into a data file.
|
|
* Lots of hashing around with Joystick support trying to achieve something
|
|
that is flexible enough to handle the zillions of possible configurations
|
|
out there. Hopefully we are approaching a workable solution.
|
|
* Better windows support in our joystick module.
|
|
* View code simplifications and optimizations contributed by Norman Vine.
|
|
|
|
* Added support for $FG_SCENERY and --fg-scenery=path so scenery can have a
|
|
different location from the base package.
|
|

|
level communications modules over to simgear.
|

|
|
|
|
|
|
New in 0.7.3
|
|
* May 18, 2000
|
|
* Added a radio stack 2 VOR/ILS and an ADF to the instrument panel.
|
|
You can change the frequencies by clicking on the knobs on the
|
|
instrument panels. You can now navigate with VOR/ADF/DME and fly
|
|
ILS approaches.
|
|
* Added a chronometer to the instrument panel.
|
|

|
|
* Added navaid database management and query code.
|
|

|
|
* Heading bug now display magnetic heading rather than true heading.
|
|
* Autopilot now has modes to track a VOR and GS.
|
|
* Added custom joystick client support so sim can be flown from a
|
|
remote joystick connected to another machine. This is in support of
|
|
some custom hardware located in the human factors research lab of the
|
|
university of minnesota.
|
|
* HUD controls are a bit different "h" toggles through day/night/off
|
|
modes and "H" cycles through brightness levels.
|
|
* Norman Vine contributed code to optionally do antialiased hud lines
|
|
on hardware that supports this. Norman also contributed additional
|
|
hud cleanups and updates.
|
|
* Updates to JSBsim flight dynamics code that includes a generic
|
|
reconfigurable flight control system, a initial state trimming routine,
|
|
support for wind and weather, support for flaps, independent trim control,
|
|
config files changes
|
|
* Updates to LaRCsim flight dynamcis code contributed by UIUC that
|
|
allows loading aircraft specifications at runtime from config files.
|
|
UIUC is using flightgear as a platform to do icing research. The UIUC
|
|
aircraft use the c172 gear model for now which causes some weirdness
|
|
on the ground for some of the larger aircraft.
|
|
* Flight model no longer has to be chosen at compile time.
|
|
* Separated ephemeris code from the actual sky rendering code and gave
|
|
this whole section a big overhaul. The moon should now consistantly
|
|
have the correct phase.
|
|
* Rebuilt the sky dome using ssg.
|
|
* Removed dependencies on mat3.h and friends (old srgp support lib)
|
|
* Airport lookups now done through gdbm (a light weight embedded database.)
|
|
* Converted ssgVTable's to ssgVtxTables which do proper memory
|
|
management and should facilitate use of compiled vertex arrays once
|
|
ssg add support for these.
|
|
* Overhauled autopilot internals, separated out the gui controls from
|
|
the actual autopilot code.
|
|
* Cygwin32 build fixes
|
|
* MSVC++ build fixes
|
|
* Mac build fixes
|
|
|
|
New in 0.7.2
|
|
* February 17, 2000
|
|
* Lots of code reorganizations
|
|
* Build requires plib-1.1.x
|
|
* Build requires SimGear-0.0.x
|
|
* LaRCsim/c172 is now the default aircraft model.
|
|
* Added flaps support to control model.
|
|
* Lots of updates and tweaks for the LaRCsim/c172 model.
|
|
* Use a more standard texture/blend mode combination for sun/moon halos to
|
|
avoid render path that's not supported by all cards/drivers.
|
|
* Change reported speed on hud from V_equiv_kts to V_calibrated_kts
|
|
* Instrument panel rewrite by David Megginson. This isn't quite as flashy
|
|
as the first pass, but is much more functional, plays much better with
|
|
opengl, and it should be relatively easy for someone with graphical skills
|
|
to make it look more spiffy.
|
|
* MacOS fixes contributed by Darrell Walisser.
|
|
* Many JSBsim updates.
|
|
* Added a screen snapshot facility (F3).
|
|
* Added a load/save state function contributed by David Megginson.
|
|
* Added support for various I/O protocols and channels so that flightgear
|
|
can communicate with itself and other programs through a variety of means.
|
|
* Bug fix: The aircraft model used for external views was being included in
|
|
the height above terrain check so when the view position and the aircraft
|
|
model collided the current altitude kept getting pushed up to compensate,
|
|
but of course the aircraft model would get pushed up as well because it
|
|
tracks the current aircraft position and orientation. Thus you had a never
|
|
ending cycle ...
|
|
* Oliver's multiplayer network code now moved to his own subdirectory:
|
|
NetworkOLK
|
|
* Added simulated cloud puffs as we pass through the cloud layer.
|
|
* Cleaned up some memory leaks occuring between ssg and flightgear.
|
|
* Update to Christian's weather data base code.
|
|
|
|
New in 0.7.1
|
|
* Durk Talsma added a nifty cloud layer.
|
|
* Default to Christian Mayer's new weather system.
|
|
* Added routines to do screen printing contributed by Mark Vallevand.
|
|
* Added routines to do screen shots to ppm graphics file (all platforms)
|
|
contributed Rich Kaszeta.
|
|
* Added a magic carpet (aka slew) mode.
|
|
* Added a hot air balloon simulator mode. (alpha)
|
|
* Added a simple (direct lincage) autocoordation feature.
|
|
* Added a mode to control view (side to side and up and down) with the mouse.
|
|
* Fixed a DEM decoding problem which caused most of the terrain to be 256
|
|
meter too high (and regenerated the world scenery with proper elevations.)
|
|
* Updates to JSBsim.
|
|
* Added support for a pilot view offset from the center of gravity.
|
|
* Various platform portability fixes.
|
|
* Updated time-offset/syncing command line options.
|
|
* Updated the FDM <==> Flight Gear interface to be more object oriented.
|
|
This should hopefully pave the way for being able to simulate several
|
|
concurrent entities.
|
|
* Removed unimplemented menu entries.
|
|
* Various scenery tools changes and enhancements in preparation for adding
|
|
runways (hopefully for the next release.)
|
|
|
|
New in 0.7.0
|
|
* Autopilot can now fly great circle routes.
|
|
* Incorporated a first stab at some networking code contributed by Oliver
|
|
Delise.
|
|
* Added Christian Mayer's new weather subsystem.
|
|
* Started adding support for "external" views ... still needs some work.
|
|
* Added a flight model acceleration funtion.
|
|
* Added support for mouse yoke control contributed by David Megginson.
|
|
* FDM model hertz now definable from the command line.
|
|
* Added initial timezone support so the user can have better control and more
|
|
options for setting the starting time of the sim.
|
|
* We now draw nonexistant tiles as ocean which means we only have to create
|
|
and distribute tiles that contain some sort of land mass.
|
|
|
|
* Replaced basic render engine with plib's ssg (simple scene graph).
|
|
* Now expect plib to be installed in it's one true and official location.
|
|
* Added support for timegm() if it exists which explicitely expects GMT input.
|
|
* A bit of your basic code reorganization and shuffling.
|
|
|
|
* Removed tools dependency on libgfc. Functionality is now covered by
|
|
shapelib which has been added into the Tools tree.
|
|
* Added support for the wonderful GSHHS global land mass data set.
|
|
* Removed dependecy on process-dem.pl script.
|
|
* Created a new distributed/parallel tile build system ... hmmm kind of super
|
|
computer or beowulf style stuff for getting large chunks of scenery built
|
|
as fast as possible.
|
|
* Only generate tiles that have land mass data since the sim can recreate pure
|
|
ocean tiles on the fly.
|
|
* First stab at a water flattening scheme to prevent oceans, lakes, and rivers
|
|
from running up and down the sides of hills.
|
|
* Changed the default "Work/" subdirectory layout.
|
|
* Updates to better handle segment boundaries in preparation for real airport
|
|
runway and lighting modeling.
|
|
* Updates and enhancements to my polygon management class.
|
|
|
|
* Updates to JSBsim.
|
|
* Updates to Tony's c172 model.
|
|
* Updated getting started guide from Micheal Basler.
|
|
|
|
* FreeBSD portability tweaks.
|
|
* MACos portability tweaks.
|
|
* Borland C++ tweaks.
|
|
* MSVC++ tweaks.
|
|
|
|
New in 0.6.0
|
|
* Tons of improvements with scenery creation. Inter-tile gaps have been
|
|
fixed, distorted textures have been fixed, real coastlines have been added,
|
|
and many other subtle improvements.
|
|
* Tools for parallelizing the scenery building tasks. For instance by using
|
|
20 machines in parallel, scenery for the entire USA can be regenerated in
|
|
just over 4 hours vs. 70+ hours on a single machine.
|
|
* Texture scale can be specified (and changed)( in the materials file. The
|
|
sim must be rerun for the change to take effect.
|
|
* Windows now uses plib joystick code so rudder pedals should now work.
|
|
* Now builds against Steve Baker's plib (portable game devel library)
|
|
distributed separately (www.woodsoup.org/~sbaker/plib/)
|
|
* Many source code changes for the MacOS port contributed by Darrell
|
|
Walisser (the port isn't quite there yet ...)
|
|
* Source code changes for better compiling with the Borland compiler.
|
|
* Source code changes for better compiling with the native Irix compilers.
|
|
* Fixed a bug so you can now fly across the international date line (or
|
|
more precisely the division between longitude = +/-180.
|
|
* Tweaks to the Astro section contributed by Durk Talsma.
|
|
* Autopilot improvements contributed by Norman Vine.
|
|
* Fonts/characters now drawn with texture maps for increased speed.
|
|
* Instrument panel can be toggled on and off with "P".
|
|
* GUI interface for tweaking some autopilot parameters.
|
|
* HUD appearance and layout changes contributed by Norman Vine, includes
|
|
faster font drawing for much better performance.
|
|
* Reset function added to reset you to your starting conditions.
|
|
* GUI function to enter a new airport id (and be transported there)
|
|
* Added serial output support for an "in-development" full motion cockpit.
|
|
* "Just in time" texture loading to reduce initial sim loading time.
|
|
|
|
|
|
New in 0.59 (This is an intermediate/stepping stone release. Skip this
|
|
release if you are interested in stability.)
|
|
* IRIX portability changes and support for native SGI compilers.
|
|
* Solaris portability tweaks
|
|
* Incorporated some MacOS portability changes (although the port is not
|
|
yet complete.)
|
|
* Changes to allow adjustment of the autopilot settings while it is
|
|
activated.
|
|
* Began complete overhaul of scenery generation tools.
|
|
* Fixed a view frustum culling bug.
|
|
* separated lib GPC (generic polygon clipper.) GPC is not "freeware" and
|
|
the author has explicitely refused our request to distribute source code
|
|
for this library with Flight Gear.
|
|
* updated installation and getting started guide
|
|
* switched to a simpler, lighter weight frame rate calculation method.
|
|
* new tile division scheme.
|
|
* GPS serial *output* fixes.
|
|
* Added a nifty halo to both the sun and moon. Preparation for allowing
|
|
subtle moon lighting effects at night.
|
|
* Incorporated Jon Berndt's new C++ flight model rewrite.
|
|
* Autopilot settings can be adjusted while active.
|
|
* Updates to the instrument panel.
|
|
* Fixed AOA reading on the HUD.
|
|
* Added random splash screens.
|
|
* Modified scenery loader to accept tri-fans.
|
|
* Other non-backwards compatible changes to scenery file format and tile
|
|
layout.
|
|
|
|
|
|
New in 0.58
|
|
* Added JSBsim alpha code ... this is Jon S. Berndts alpha FDM rewrite.
|
|
Still lots to do, but you can watch a balistic flight for a short time.
|
|
* Renamed Simulator/Flight to Simulator/FDM
|
|
* Tweaks to assist building FGFS on solaris platforms.
|
|
* Moved Lib/DEM to Tools/DEM
|
|
* Started preparations for scenery generation tools overhaul.
|
|
* More MSVC++ support.
|
|
* Removed code that made the sun bigger at the horizon since this is just
|
|
an optical illusion in real life.
|
|
* Bug fixed so that the sim can start out at an airport below sea level.
|
|
|
|
New in 0.57
|
|
* Converted to a simpler frame rate counting method.
|
|
* Fixed the AOA reading on the HUD.
|
|
* Removed gpc from the Lib section of distribution by request of the
|
|
gpc Author. The gpc license is unfortunately not compatible with
|
|
the GPL. I may look for an alternative library, or just require
|
|
that developers download this library separately.
|
|
* First slew of changes from the MacOS porting effort contributed by
|
|
"Robert Puyol" <puyol@abvent.fr>.
|
|
* Support for an arbitrary number of serial ports + additional serial port
|
|
output tweaks.
|
|
* Serial output tweaks to make things more robust and act more like a GPS.
|
|
* Portability enhancements for Borland, Solaris, and SGI.
|
|
* Some internal class renaming and reorganizations. fgFLIGHT becomes FGState.
|
|
fgCONTROLS becomes FGControls.
|
|
* Started work on an "external" flight model so the sim can be driven from
|
|
external input (serial port, network, file, etc.)
|
|
* Fixed a problem that creeped in with setting the initial startup altitude.
|
|
This could cause an unrecoverable bounce and you'd end up flipped on your
|
|
back. Should be fixed now.
|
|
* Sun now appears to grow in size as it gets very low in the horizon.
|
|
* Fixed a view frustum culling bug where the scene was not accurately culled
|
|
when your view was anything other than straight forward.
|
|
|
|
New in 0.56
|
|
* Changed default HUD units to the more standard feet units. You can still
|
|
use meters by specifying the command line option "--units-meters".
|
|
* Added some initial joystick support using Steve's joystick interface class.
|
|
This works great under Linux, but Steve's class now needs to be ported to
|
|
Windoze and other platforms.
|
|
* Also added a fall back to the GLUT joystick routines for windows (until
|
|
we can find better joystick support.)
|
|
* Added some initial serial port support for acting like gps and outputing
|
|
nmea data such that could be fed into a flight map software package.
|
|
* Miscellaneous code clean ups, portability improvements, and optimizations.
|
|
* Switched to a streams based error/debug logging system that can be
|
|
completely stripped out for a release build (./configure --without-logging)
|
|
* Support for cygwin32 b20 compiler (latest release)
|
|
* Continued progress on instrument panel
|
|
* Support for starting fgfs at higher resolutions.
|
|
|
|
New in 0.55
|
|
* New version of gpc (generic polygon clipping library) from
|
|
http://www.cs.man.ac.uk/aig/staff/alan/software/
|
|
* Brakes (use "b" to toggle)
|
|
* Added an altitude hold module to the autopilot. Lock your current altitude
|
|
with "ctrl-a", "cntr-a" again will deactivate. (Also lock your current
|
|
heading with "ctrl-h", and again to deactivate.)
|
|
* Added a terrain following module ... "ctrl-t" to activate.
|
|
* Added an autothrottle ... "ctrl-s" to activate.
|
|
* Fixes so that terrain tools will work in windoze.
|
|
* More STL & Compiler compatibility fixes.
|
|
* Changes to use a Point3 class.
|
|
* Fixed win95/98 time problem that limited fps to about 18.3
|
|
|
|
New in 0.54
|
|
* Implimented audio envelopes so that pitch of engine changes with throttle
|
|
* Textured moon, and rewritten/restructured Astro code.
|
|
* More optimizations and code cleanups. (Norman Vine, Bernie Bright, Charlie
|
|
Hotchkiss.)
|
|
* Bug fixed that was causing odd display artifacts due to a degenerate
|
|
fragment being created for every tile.
|
|
* Bug fixed that caused scenery generation to go bad (misplaced fclose on an
|
|
invalid file descriptor.)
|
|
* Code changes to support g++ 2.7 STL (from Bernie Bright)
|
|
|
|
New in 0.53
|
|
* Some initial "GameGLUT" support contributed by Gary R. Van Sickle
|
|
(tiberius@braemarinc.com)
|
|
* Tracked down and eliminated some memory access type bugs that were
|
|
causing segfaults on some platforms, with some compilers using various
|
|
optimization flags.
|
|
* Assorted code optimizations submitted by Norman Vine.
|
|
* Renamed fg -> fgfs
|
|
* Shuffled files.
|
|
- Created a new directory Simulator/Airports/ to handle airport data
|
|
specific tasks
|
|
- Created Simulator/Object/ to handle basic rendering objects
|
|
* Panel code update from Friedemann Reinhard (use --enable-panel to activate)
|
|
* Contributions from Bernie Bright
|
|
- Created some new classes to enable pointers-to-functions and
|
|
pointers-to-class-methods to be treated like objects. These objects
|
|
can be registered with fgEVENT_MGR.
|
|
- File "Include/fg_callback.hxx" contains the callback class defns.
|
|
- Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
|
|
some minor tweaks to STL usage.
|
|
- Added file "Include/fg_stl_config.h" to deal with STL portability
|
|
issues. Added an initial config for egcs (and probably gcc-2.8.x).
|
|
Don't have access to Visual C++ so I've left that for someone else.
|
|
- This file is influenced by the stl_config.h file delivered with egcs.
|
|
- Added "Include/auto_ptr.hxx" which contains an implementation of the
|
|
STL auto_ptr class which is not provided in all STL implementations
|
|
and is needed to use the callback classes.
|
|
- Deleted fgLightUpdate() which was just a wrapper to call
|
|
fgLIGHT::Update().
|
|
- Modified fg_init.cxx to register two method callbacks in place of the
|
|
old wrapper functions.
|
|
- The new classes in libmisc.tgz define a stream interface into zlib.
|
|
I've put these in a new directory, Lib/Misc. Feel free to rename it
|
|
to something more appropriate. However you'll have to change the
|
|
include directives in all the other files. Additionally you'll have
|
|
add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
|
|
|
|
The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
|
|
test so I've included the required changes in config.tgz.
|
|
|
|
There are a fair few changes to Simulator/Objects as I've moved
|
|
things around. Loading tiles is quicker but thats not where the delay
|
|
is. Tile loading takes a few tenths of a second per file on a P200
|
|
but it seems to be the post-processing that leads to a noticeable
|
|
blip in framerate. I suppose its time to start profiling to see where
|
|
the delays are.
|
|
|
|
I've included a brief description of each archives contents.
|
|
|
|
Lib/Misc/
|
|
zfstream.cxx
|
|
zfstream.hxx
|
|
C++ stream interface into zlib.
|
|
Taken from zlib-1.1.3/contrib/iostream/.
|
|
Minor mods for STL compatibility.
|
|
There's no copyright associated with these so I assume they're
|
|
covered by zlib's.
|
|
|
|
fgstream.cxx
|
|
fgstream.hxx
|
|
FlightGear input stream using gz_ifstream. Tries to open the
|
|
given filename. If that fails then filename is examined and a
|
|
".gz" suffix is removed or appended and that file is opened.
|
|
|
|
stopwatch.hxx
|
|
A simple timer for benchmarking. Not used in production code.
|
|
Taken from the Blitz++ project. Covered by GPL.
|
|
|
|
strutils.cxx
|
|
strutils.hxx
|
|
Some simple string manipulation routines.
|
|
|
|
Simulator/Airports/
|
|
Load airports database using fgstream.
|
|
Changed fgAIRPORTS to use set<> instead of map<>.
|
|

|
|
Returns true if found.
|
|
|
|
Simulator/Astro/
|
|
Modified fgStarsInit() to load stars database using fgstream.
|
|
|
|

|
|
Modified fgMATERIAL_MGR::load_lib() to use fgstream.
|
|
Many changes to fgMATERIAL.
|
|
Some changes to fgFRAGMENT but I forget what!
|
|
|
|
New in 0.52
|
|
* Stars added in 8 stages as sky gets darker for a smoother more realistic
|
|
transition.
|
|
* rewrote star loader to significantly improve load times.
|
|
* Tweaked sky brightness and dawn/dusk colors.
|
|
* Fixed a small problem with moon rendering.
|
|
* Fog color tries to track the sky color at the center of view in sunrise
|
|
and sunset situations.
|
|
* Optimizations from Norman Vine
|
|
* Code fixes and tweaks from Charlie Hotchkiss.
|
|
* Added an --enable/disable-sound option.
|
|
* Added a pause key "p"

* Added command line options to specify initial position and orientation.
|
|
* Added command line option to start in paused or unpaused state.

New in 0.51
|
|
* Translucent menus
|
|
* Various HUD intensities so you can find something that is readable for the
|
|
current conditions and lighting.
|
|
* Tie visibility to far clip plane & view frustum culling so reducting
|
|
visibility can increase frame rates by increasing what is culled.
|
|
* Fixed stupid bug with misplaced initial position.
|
|
* Hopefully fixed a bug when parsing system.fgfsrc on windoze.

|
|
* HUD updates from Charlie Hotchkiss (ladder number rotate w/ ladder, control
|
|
position indicators are back)
|
|
* Only draw the PUI cursor if Mesa/Glide/Fullscreen.
|
|
* Added mipmapping.
|
|
* Calculate the model view transformation matrix once per tile per iteration.
|
|
Then glLoadMatrixd() it for each fragment rather than calling push(),
|
|
translate(), pop().
|
|
* Added a basic splash screen.
|
|
* Added support for switching between fullscreen and window mode for
|
|
Mesa/3dfx/glide.
|
|
* added an enable/disable splash screen option
|
|
* added an enable/disable intro music option
|
|
* added an enable/disable instrument panel option
|
|
* added an enable/disable mouse pointer option
|
|
* Ground collision detection. You can now land or test for collision with
|
|
any scenery surface.
|
|
* Converted angle of attack scale into a radio altimeter.

|
|
* Managment of multiple textures
|
|
* Incorporated Friedemann Reinhard's initial panel code.
|
|
* Fog mode is now GL_FOG_EXP2 instead of GL_FOG_LINEAR
|
|
* Build the non-shared pieces of the FG sim as static libs.
|

|
New in 0.48
|
|
* Incorporated Steve Baker's PUI user interface library written
|
|
entirely on top of OpenGL
|
|
* Incorporated Steve Baker's Audio library which currently only
|
|
supports Linux, but a win32 port is very close to being done.
|
|
* Sort object fragments by material property before rendering. This
|
|
will be a big help to performance when we start including objects
|
|
with a wide variety of material properties and textures.
|
|
* Overlapped scenery tiles to reduce the chance of an occasional
|
|
floating point precission induced gaps.
|
|
* Fixed a bug in zlib exposed by Borland Win32 compiler.
|
|
* Impose a maximum triangle area during scenery generation so even
|
|
very flat areas will get split into a few smaller sub triangles.
|
|
* Fine grained (fragment level) view frustum culling.
|
|
* view transformation optimizations -- Norman Vine.
|
|
* Fixed polygon winding problem in scenery generation, so all
|
|
tri-strips are wound counter clockwise (opengl default).
|
|
|
|
New in 0.47
|
|
* Course (per tile) view frustum culling.
|
|
* Added a command line option to specify --fg-root which will override
|
|
$FG_ROOT
|
|
* Hard coded default locations for FG_ROOT for situations when nothing
|
|
is specified. Unix = /usr/local/lib/FlightGear Win32 = \FlightGear
|
|
* Restructured the command line processing code so that it can process
|
|
these sames comands (one per line) out of a config file.
|
|
* Added a command line option to specify field of view. This is
|
|
adjustable at run time using "X / x". Supporting code contributed
|
|
by Norman Vine.

* Added an option to enable/disable wireframe rendering.
|
|
* Added an option to enable/disable fog/haze.
|
|
* Added an option to enable/disable sky blending.
|
|
* Added an option to select smooth/flat polygon shading.
|
|
* Added an option to enable full-screen mode.
|
|
* Added a visual frame rate counter on the HUD. (Contributed by Durk Talsma)
|
|
* Autopilot updates (Jeff Goeke-Smith)
|
|
* Added an option to control the number of neighboring tiles that are drawn
|
|

|
New in 0.44:
|
|
* Fixed a horible bug that cause the time to be *WAY* off when
|
|
compiling with the CygWin32 compiler.
|
|
* Wrap up zlib so we can conditionally compile back in normal behavior
|
|
on systems that have trouble building zlib.
|
|
* Minor adjustment to texture coordinate generation to reduce texture
|
|
swimming.
|
|
* Added a command line option to enable/disable texture maps
|
|
* Minor transformation adjustments to try to keep scenery tiles closer
|
|
to (0, 0, 0) GLfloats run out of precision at the distances we need
|
|
to model the earth, but we can do a bunch of pre-transformations
|
|
using double floats and then cast to GLfloat once everything is
|
|
close in where we have less precision problems.
|
|
* command line option to set starting position by airport ID
|
|
* Cleaned up initialization sequence to eliminate interdependencies
|
|
between sun position, lighting, and view position. This creates a
|
|
valid single pass initialization path.
|
|
* use already calculated LaRCsim values to create the roll/pitch/yaw
|
|
transformation matrix
|
