This is another update for the cloud code, a lot of lines but this time I have started to add the doxygen doc.
Misc
====
- corrected a bug when RTT is not available, the current rendering context was
altered
- if RTT is not available then 3d clouds are not drawn at all
- impostors lighting is now recomputed when the sun changes position
- distant objects are no more seen in front of clouds
- blending of distant clouds is a bit better now
- litle optimization of code (uses a less cpu time)
- use layer wind speed and direction (no more hardcoded wind)
- fov is no more hardcoded
Changes
=======
- clouds (cu only) are dissipating/reforming (experimental)
- compute a turbulence factor that depends on surrounding clouds and type of
clouds (experimental)
- clouds shapes are defined in cloudlayers.xml
- type of clouds present in a layer is also defined in cloudlayers.xml
- cloud layers are generated from metar and other misc. data (in progress)
- added a rain effect around the viewer (enabled in the rendering dialog and
when the metar property says so)
- added a lightning effect (enabled in the rendering dialog) : cb clouds spawn
new lightnings
- added a dialog to select from different weather source : metar/property,
a 'fair weather' environment and a 'thunderstorm' environment.
There are two <dme> entries in preferences.xml, resulting in two dme branches
under /instrumentation/ (dme[0] and dme[1]). The serviceable property is only
set for the second entry (dme[1]), and that one is not connected to the dme
module. Solution: Remove the first <dme> entry, and set the index explicitly
to 0 for the remaining <dme> entry.
Here are files to get automated contrails working. I've set up contrails for
the 737, using my simple, untextured contrail model. Vivian has made another
contrail model, but I'm still trying to get his to work. I'm hoping others
will try to make contrail models also.
Here's some code that defines a top to thermals. When the top of a thermal is
reached the strength is phased-out linearly over the next 100 feet of
altitude. At first I tried just capping the thermal at the top, but the
change in thermal strength was too fast for the FDM to handle well.
Included is a new version of the thermal scenario that includes a top
(height-msl) to the thermal. The default value is 5000 feet.
After applying the attached patches (based on latest CVS) you should
have a new option available within your version that should also
show up using fgfs --help, the syntax is:
fgfs --min-status={level} --show-aircraft
whereas "level" can be anything between
"alpha","beta","early-production" and "production"
Of course running something like
fgfs --min-status=alpha --show-aircraft
should not return any aircraft right now, as none of the
current aircraft definition files in your base-package is using the
required
<status></status>
tag - but you can easily give it a try by adding something like
<status>alpha</status>
The tag should be placed as a sub-tag within <sim> - so directly behind
the <description> tag would be just fine and straight-forward.
This will modify menubar.cxx/hxx so that it exports the
entire menubar (from menubar.xml) to the property tree, so that it can
now be changed dynamically using Nasal's setprop() instruction and
afterwards running a newly added fgcommand to update the menubar
based on those changes using the appropriate menubar path within
the property tree.
By default the menubar from menubar.xml will be stored within:
/sim/menubar/default
Erik:
I have moved the loading of menubar.xml into preferences.xml and
made sure that the menubar is destroyed every time a new menubar
is created.
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.
I've included the latest fixes to the Traffic Manager/AI flightplan generation
code. Most of the code changes are in AIFllightplan.cxx. This is the code
that runs without depending on predefined FlightPlans in
#FG_ROOT/Data/AI/Flightplans.i
As suggested by Dave, I've also added a new property in
preferences.xml: /sim/traffic-manager/enabled, which is used to control
whether or not the traffic manager is active.
I'm still working on a few more 737 traffic patterns, those are going to take
a little longer, so I didn't want to wait sending in this code.
Finally, I haven't put much effort into ensuring "aeronautical correctness" in
this version yet. The code works on my system, but what the AI plane do may
actaully be quite rediculous. But I'd like to leave that for the next
version.
Here's some new AI stuff.
1) AI objects must now be defined in a scenario file, not in preferences.xml
or a *-set file. (Of course this doesn't prevent objects from being created
dynamically, as with Durk's traffic manager).
2) A new demo_scenario file is attached. It creates 3 aircraft, a sailboat,
and a thunderstorm.
3) Objects without flightplans live forever.
4) FGAIShip::ProcessFlightplan() is not yet implemented.
5) preferences.xml should now define only <enabled> and <scenario>
Don't know if this was intentional, but since revision 1.128
(2003/10/01 21:15:55; david; "Add some whitespace, and initialize
the new ADF subsystem.") the ADF isn't initialized with useful
frequencies any more. It should be something in the bay area.
379 is for BRIJJ again (in the glide slope of KSFO) and 341 is
for RORAY (KOAK). Don't know what the standby frequency was before.
controls in the cockpit vs. which wheels they apply to. FlightGear now
sets /controls/gear/brake-left, /controls/gear/brake-right, and
/controls/gear/brake-parking. It should be up to the FDM to sort out
which wheels under which circumstances are affected by these controls
and ultimately what happens to the physical motion of the aircraft.
These patches add a clock instrument, which allows to model failure ("serviceable") and to adjust the time independently of the system time (defaults to GMT). The main incentive is to make the p51d clock work and adjustable via the knob.
o Offers a time string ("12:03:15") for the LCD or for LED
clocks, or an empty string in case of failure/power off. The
instrument assumes that digital clocks are battery buffered,
so they will be updated even if there's nothing on the display.
o Offers the number of seconds since midnight for analog
clocks, like in the p51d. This number is not increased
if !serviceable. So the clock will stand still and continue
where it stopped when it's serviceable again.
I did not consider voltage yet, because the Mustang's clock will need a lot more current than the LCD clock. The instrument is updated 4 times per second but returns immediately if neither time nor offset changed. The function getGMTString() in fg_props.cxx could be removed after applying these patches.
There are a number of little changes. Tested with current cvs as of 20:30EST
04Feb. Actually been running since the beginning of January with these
patches. All changes work without crashing with the current base package cvs,
but there are some visual problems with the views (other than pilot view)
without changes to the base package.
As soon as you can build test and commit I can add in those base package
updates that will make it all work nicely. I will also go through all the 3D
Aircraft configs to make sure the change in the "pitch-offset" for cockpit
views (see below) are made to maintain current behavior.
Here are the files (changes listed below):

there was only the addition of the 5th view discussed, and a developer noted
that the Lookfrom Tower view was useful for multi-aircraft development. So
this patch preserves the new 5th view, returns the Lookfrom Tower and removes
the second Lookat Tower. One is enough for now IMHO, but still open for
discussion of course.
