2852f27bdc Uninitialized data problem. As it turns out, this never bit us because
the _chord member is only used uninitialized in circumstances where the
result is thrown away.  Still, bad practice.  Found with valgrind.

04e083083d Need to call recalc() on the RigidBody during solution, or else it
won't apply the right gross weight due to fuel differences.

When solving for zero force, do so in the global frame, not the
aircraft's.  In principle, this shouldn't matter (zero is zero in all
frames), but in practice this should help to avoid oscillations.
Calculating lift as force perpendicular to the ground (and not the
wing plane) is clearly the Right Thing, anyway.

Also added support for a /yasim/gross-weight-lbs property, which
should be generically useful.

713920356b Property name typo. This resulted in all temperatures being 273K,
which is far too warm at altitude.  Thus, air density (and aircraft
performance) was too low for a given altitude.

7e63c0f6e8 Modify solution heuristics. Do the cruise AoA and tail incidence only
when the lift/drag are really solid.  And defer the approach trim until

8ae364a220 Jim Wilson:
This is a small fix for what turned out to be a major bug.  Ground elevation
was calculated incorrectly when distant from one of the view locations. This
resulted in several problems including bizarre gear trimming, mid air
"crashes" (as in thinking we hit the ground) and so on when close to or on the
ground.

Unfortunately it does require a second ssg traversal when in tower view
(only), but the increased load isn't all that noticable.  For the time being
this really is the best solution.  In a future update I will be eliminating
the unecessary per frame traversals for the static views (without having to
maintain multiple ssgRoots).

When we go to multiple FDM instances we will perhaps need to put the ssg
traversal and ground elevation queries for the FDMs into an event timer that
updates the FDMs ground elevation in a round robin fashion (maybe every 1/n
seconds where n is the number of FDM instances running).

b1674cb506 From: "Jim Wilson" <jimw@kelcomaine.com>
This is a new improved patch for the previous tile manager fixes.

Rather than building dependencies between FGlocation or the viewer or fdm with
tilemgr what I ended up doing was linking the pieces together in the Mainloop
in main.cxx.  You'll see what I mean...it's been commented fairly well.  More
than likely we should move that chunk somewhere...just not sure where yet.

The changes seem clean now. As I get more ideas there could be some further
improvement in organizing the update in tilemgr.  You'll note that I left an
override in there for the tilemgr::update() function to preserve earlier
functionality if someone needs it (e.g. usage independent of an fdm or
viewer), not to mention there are a few places in flightgear that call it
directly that have not been changed to the new interface (and may not need to be).

The code has been optimized to avoid duplicate traversals and seems to run
generally quite well.  Note that there can be a short delay reloading tiles
that have been dropped from static views.  We could call the tile scheduler on
a view switch, but it's not a big deal and at the moment I'd like to get this
in so people can try it and comment on it as it is.

Everything has been resycned with CVS tonight and I've included the
description submitted earlier (below).

Best,

Jim

Changes synced with CVS approx 20:30EDT 2002-05-09 (after this evenings updates).

Files:

 or

Description:
In a nutshell, these patches begin to take what was one value for ground
elevation and calculate ground elevation values seperately for the FDM and the
viewer (eye position).  Several outstanding view related bugs have been fixed.

With the introduction of the new viewer code a lot of that Flight Gear code
broke related to use of a global variable called "scenery.cur_elev".

Therefore the ground_elevation and other associated items (like the current
tile bucket) is maintained per FDM instance and per View.  Each of these has a
"point" or location that can be identified.  See changes to FGLocation class
and main.cxx.

Most of the problems related to the new viewer in terms of sky, ground and
runway lights, and tower views are fixed.

There are four minor problems remaining.  1) The sun/moon spins when you pan
the "lookat" tower view only (view #3).  2) Under stress (esp. magic carpet
full speed with max visibility), there is a memory leak in the tile caching
that was not introduced with these changes.  3) I have not tested these
changes or made corrections to the ADA or External FDM interfaces.  4) The
change view function doesn't call the time/light update (not a problem unless
a tower is very far away).

Details:
FDM/flight.cxx, flight.hxx - FGInterface ties to FGAircraftModel so that it's
 location data can be accessed for runway (ground elevation under aircraft)
 elevation.

FDM/larsim.cxx, larcsim.hxx - gets runway elevation from FGInterface now.
Commented out function that is causing a namespace conflict, hasn't been
called with recent code anyway.

FDM/JSBSim/JSBSim.cxx, YASim/YASim.cxx - gets runway elevation from
FGInterface now.

Scenery/newcache.cxx, newcache.hxx - changed caching scheme to time based
(oldest tiles discard).

Scenery/tileentry.cxx, tileentry.hxx - added place to record time, changed
rendering to reference viewer altitude in order to fix a problem with ground
and runway lights.

Scenery/tilemgr.cxx, tilemgr.hxx - Modified update() to accept values for
multiple locations.   Refresh function added in  order to periodically make
the tiles current for a non-moving view (like a tower).

Main/fg_init.cxx - register event for making tiles current in a non-moving
view (like a tower).

Main/location.hxx - added support for current ground elevation data.

Main/main.cxx - added second tilemgr call for fdm, fixed places where viewer
position data was required for correct sky rendering.

Main/options.cxx - fixed segfault reported by Curtis when using --view-offset
command line parameter.

Main/viewer.cxx, viewer.hxx - removed fudging of view position. Fixed numerous
bugs that were causing eye and target values to get mixed up.

4efbc97a4b Revert the recent changes to Atmosphere.cpp. They were actually in
the wrong place.  The Atmosphere::getStd*() calls are used by the
solver, and thus really need to return values for a "standard"
atmosphere.  Otherwise, an aircraft started up in Moscow will behave
differently than one initialized in Cairo. :)

The place where environmental pressure and temperature get inspected
at runtime is in YASim.cxx.  The changes there, happily, end up being
even smaller than the ones to Atmosphere.  This ends up replacing code
only, and removing some comments.

f9f05aa870 Bernie Bright:
Here is the new super improved telnet property interface.  CVS changelog
is at the end of this message.  Once this new telnet code is in and
compiles every where we can remove Network/props.[ch]xx.  I've added a
--telnet=<port> command line option to invoke the new server.  Later on
we could remove the --props option, or least change it to invoke the new
server.  I'll let you decide.

I've added some new commands to the telnet interface:

view next      Select the next view.
view prev      Select the previous view.
view set <n>   Select view 'n'
view get       Return index of current view

I'm not sure if these same effects could be achieved through property
operations.  The commands provide a convenient shortcut in any case.

I'm also planning on adding a panel command to manipulate panels and
objects contained therein (eg simulated mouse clicks).  There is going
to be some commonality with the command objects so we may need to
rationalize this in the near future.

Finally, I've also included my python stuff.  This is still very much a
work in progress, basically I've been using it to test the new telnet
server.  I have  tested it with python 2.2.  Feel free to add it to the
repository if you want.  I would suggest a scripts/python directory

CVS Changelog

8a5cdbdbc6 Finished off the atmosphere model (Troposphere and lower
Stratosphere).  The atmospheric properties are as follow:

/environment/temperature-sea-level-degc
/environment/temperature-degc
/environment/pressure-sea-level-inhg
/environment/pressure-inhg
/environment/density-sea-level-slugft3
/environment/density-slugft3

Setting either the sea-level or altitude value automatically sets the
other value appropriate, except for temperature at altitude above the
Troposphere (where there's no reliable way to back-calculate it).  The
atmosphere model appears in the atmosphere_data array in
environment.cxx, and can easily be extended into the upper
stratosphere and beyond.

These are not yet tied into the FDMs or steam module.
