+
+	* simgear/props/: props.cxx, props.hxx, props_io.cxx: Property
+	  system optimizations
+
+	  Profiling startup with the new effects code exposed some
+	  performance gotchas. The objective is to reduce allocation of
+	  std::string temporaries, especially when looking up node path
+	  names. Also, I changed some paths to initialize strings with
+	  strings instead of char *; this causes less allocation, at least
+	  with glibc. Also, eliminate the old version of find_node and its
+	  helper functions by writing the template version of find_node_aux
+	  to handle an explicit index parameter.
+
+	  Also, add const char[] as an internal property type
+
+	  This doesn't actually add a new type to the property system, but
+	  allows using character arrays as arguments to certain templates.

+
+	   Brian Schack reported that the traffic scheduler messes up the
+	  timestamps
+	   of the atlas network output. As it turns out, the c library
+	  functions
+	   asctime, and gmtime use a static copy of the tm struct to do the
+	  internal
+	   formatting. Our linux port of the SGTime class, incidentally,
+	  also stored
+	   it's master time stamp in this very same struct. Thus,
+	  formatting an
+	   arbitrary time value, would have the unwanted side effect of
+	  time travel.
+	   Usually, this would go unnoticed, because the actual time
+	  parameters would
+	   be updated before any damage could be done. But unwanted side
+	  effects, as
+	   in Brian's example could occur.
+
+	   On the MSVC port this appears to not have been a problem. Since
+	  that port
+	   used a copy of the tm struct to store it's master time stamps.
+	  Since the
+	   MSVC code also compiles cleanly on linux, it seems to be the way
+	  to go to
+	   use that approach. In addition, it also removes some conditional
+	  compile
+	   directives.
+
+	   I've only run a short test, but didn't see any undesirable side
+	  effects.

+	  rather than generating a completely new Geode for each cloud.
+	  This saves sorting and display time.	- Add controls to Rendering

+	  visibility and the number of different types of cloud.  - Add
+	  some variance to the sort back-off to avoid all clouds being
+	  sorted at the same time.  - Pack attributes into vectors for
+	  performance - Re-order the cloud type determination code so that
+	  if a cloud layer could either be stratus or cumulus, cumulus is
+	  used.  - Lowered the cloud level in the standard cloud
+	  configuration slightly so a cumulus layer is generated rather

+
+	  These last two mean that you should see some 3D cumuli if

+
+	  Well, the cause was a bug in my code, but it didn't expose itself
+	  until we moved to multiple cameras. The attached patch fixes the
+	  problem.
+
+	  I've also put in a new heuristic to improve the frame-rate.
+	  Clouds that are already sorted are likely to still be sorted in

+	  intuitive
+
+		 osg::Vec4f p = vm *
+	  osg::Vec4f(_cloudsprites[i]->position.osg(), 1.0f);
+
+	  needs to be replaced with...
+
+		 osg::Vec4f p =
+	  vm.preMult(osg::Vec4f(_cloudsprites[i]->position.osg(), 1.0f);
+
+	  The patch also optimizes the distance calculation - it evaluates

+	  computation to a dot- product instead of a matrix multiplication.

+	  It fixes the following issues (to a greater or lesser extent): 1)
+	  Performance. Quad trees used to improve culling, and the sprites
+	  are placed on the surface of a sphere rather than randomly
+	  throughout the cloud, requiring fewer textures. This saves about
+	  5-10fps on my machine.  2) Disabled 3D clouds have no performance
+	  impact. Previously they were still in the scenegraph. Now they
+	  are removed.	3) Clouds are now loaded on start-up, and don't
+	  require the scenario to be changed, they also work with METAR.
+	  4) The cloud field is shifted as you travel. There's a small bug
+	  in that the clouds "jump" as you reach the edge of the field.  5)
+	  Iterative sorting of sprites. This doesn't appear to solve the
+	  alpha blending problem completely, but may help a bit.

+	  Sync with Nasal upstream (Melchior already had a chance to test
+	  this, so hopefully not too much breaks).  New syntax features:
+
+	  1. Call-by-name function arguments.  You can specify a hash
+	  literal in place of ordered function arguments, and it will
+	  become the local variable namespace for the called function,
+	  making functions with many arguments more readable.  Ex:
+
+	     view_manager.lookat(heading:180, pitch:20, roll:0, x:X0, y:Y0,
+	  z:Z0,
+				 time:now, fov:55);
+
+	  Declared arguments are checked and defaulted as would be
+	  expected: it's an error if you fail to pass a value for an
+	  undefaulted argument, missing default arguments get assigned, and
+	  any rest parameter (e.g. "func(a,b=2,rest...){}") will be
+	  assigned with an empty vector.
+
+	  2. Vector slicing.  Vectors (lists) can now be created from
+	  others using an ordered list of indexes and ranges.  For example:
+
+	     var v1 = ["a","b","c","d","e"]
+
+	     var v2 = v1[3,2];	 # == ["d","c"];
+	     var v3 = v1[1:3];	 # i.e. range from 1 to 3: ["b","c","d"];
+	     var v4 = v1[1:];	 # no value means "to the end":
+	  ["b","c","d","e"]
+	     var i = 2;
+	     var v5 = v1[i];	 # runtime expressions are fine: ["c"]
+	     var v6 = v1[-2,-1]; # negative indexes are relative to end:
+	  ["d","e"]
+
+	  The range values can be computed at runtime (e.g. i=1;
+	  v5=v1[i:]).  Negative indices work the same way the do with the
+	  vector functions (-1 is the last element, -2 is 2nd to last,
+	  etc...).
+
+	  3. Multi-assignment expressions.  You can assign more than one
+	  variable (or lvalue) at a time by putting them in a parenthesized
+	  list:
+
+	     (var a, var b) = (1, 2);
+	     var (a, b) = (1, 2);		# Shorthand for (var a, var
+	  b)
+	     (var a, v[0], obj.field) = (1,2,3) # Any assignable lvalue
+	  works
+
+	     var color = [1, 1, 0.5];

+
+	  Comments from Till: I started the project at the end of february
+	  with a simple idea: move all 3d-model loading to the
+	  DatabasePager-thread. my first attempts looked promising, though
+	  they were a little too optimistic (or naive?). the patch has
+	  evolved a lot since.
+
+	  currently it does the following things: 1. revive SGModelLib,
+	  move functions for xml-model-loading there
+
+	  2. replace all calls to sgLoad3dModel with calls to either
+	  SGModelLib::loadModel() or SGModelLib::loadPagedModel() almost
+	  all models will be loaded by the DatabasePager. the few
+	  exceptions are: your own plane, shared models in scenery, random
+	  objects, AIBallistic models.
+
+	  3. simplify mode-loading functions (avoid passing around fg_root)
+
+	  4. avoid supurious MatrixTransform nodes in loaded models
+
+	  5. fix some memory leaks

+
+	  The cause seems to be the condition in SGMaterialAnimation.cxx
+	  l.277 ignoring any texture update by the UpdateCallback (only

+	  stateSet.  That in turn will not be created with a <texture-prop>

+

+	  thread-posix.c, thread-win32.c, threadlib.c, utf8lib.c, vector.c:
+	  Sync with Nasal CVS (soon to become Nasal 1.1).  Notable new
+	  features:
+
+	  Nasal now supports calls to "subcontexts" and errors can be
+	  thrown across them, leading to complete stack traces when call()
+	  is used, instead of the truncated ones we now see.
+
+	  Vectors can now be concatenated using the ~ operator that used to
+	  work only for strings.
+
+	  Better runtime error messages in general due to a fancier
+	  naRuntimeError() implementation
+
+	  A big data size shrink on 64 bit systems; the size of a naRef
+	  dropped by a factor of two.
+
+	  "Braceless code blocks" have been added to the parser, so you can
+	  write expressions like "if(a) b();" just like in C.  Note that
+	  there's still a parser bug in there that fails when you nest a
+	  braced block within a braceless one.
+
+	  Character constants that appear in Nasal source code can now be
+	  literal multibyte UTF8 characters (this was always supported for
+	  string literals, but character constants were forced to be a
+	  single byte).
+
+	  New modules: "bits", "thread", "utf8" and (gulp...) "io".  The
+	  bits library might be useful to FlightGear, the utf8 one probably
+	  not as Plib does not support wide character text rendering.  The
+	  thread library will work fine for spawning threads to do Nasal
+	  stuff, but obviously contact with the rest of FlightGear must be
+	  hand-synchronized as FlightGear isn't threadsafe.  The io library
+	  is no doubt the most useful, as it exposes all the basic stdio.h
+	  facilities; it's also frighteningly dangerous when combined with
+	  networked code...

+	  would pop the "mark" stack, leading to an underflow.	Introduced
+	  an OP_CONTINUE which adjusts stack but doesn't change markTop
+
+	  Re-inline the PUSH macro.  This thing is called all over the

+	  side effects, then just use another expression in the macro.
+
+	  Return an empty vector when requesting zero-length subvec, not

+
+2006-03-21 23:22  andy

+
+	  This patch fixes the sound of 737, Concorde and others, if fgfs
+	  was compiled with newer gcc versions (e.g. gcc 4.0.2). These
+	  compilers implement the c++ standard more strictly, and thus
+	  don't guarantee that c-style casted pointers to different data
+	  types really point to the same address. This is only guaranteed
+	  for union members.

+	  sg_geodesy.cxx, sg_geodesy.hxx: Mathias Fröhlich:
+
+	  The patch adds a vector lib I have put together during the last
+	  time, it is just handy and interfaces well with s(s)g*. Together
+	  with some small modifications this will later also interface well
+	  with OpenSceneGraphs vectors/matrices. Using this vector kernel
+	  is targeted to have a handy matrix/vector lib available and to
+	  provide a scenegraph independent vector type for use with a small
+	  scenegraph wrapper aimed for a smooth transition to
+	  openscenegraph.
+
+	  That vector code also includes an improoved geodetic conversion
+	  routine I have found some time ago published in the 'journal of
+	  geodesy' which avoids iterative computations for that purpose.
+
+	  Also the geodetic position class is more typesafe and unitsafe
+	  than the Point3D currently is.
+
+	  That part is relatively old and in use in my local trees for
+	  several months now.

+
+	* SimGear.dsp, SimGear.dsw, am2dsp.cfg, simgear/constants.h,

+
+	  This patch makesFlightGear at least compile on MSVC. I hope I
+	  have removed reference of my other local changes. DSP and DSW
+	  files are included for reference. They have been reconstructed
+	  with am2dsp.pl. I had to introduce a change to am2dsp because of
+	  the need of filenames with embedded spaces. (Yuck)
+
+	  The major direction is to remove clutter like the
+	  _USE_MATH_DEFINES and have it on the compiler command line sice
+	  there is no central include file. You will have to put it on the
+	  command line for your locale Project files, if it not there,
+	  already. I added the _CRT_SECURE_NO_DEPRECATE define for 2005,
+	  since it does no harm to other VC version.
+
+	  Third Party Libs like plib, OpenALSDK, freeglut, pthreads-win32,
+	  zlib are unpacked as is side by side. Only change put the
+	  includes of OpenAL into include/AL rather directly into include.

+2006-01-30 11:56  ehofman
+
+	* simgear/props/: props.cxx, props.hxx: Melchior FRANZ:
+
+	  add optional arg to SGPropertyNode::addChangeListener that
+	  triggers the listener function call initially. This is useful for
+	  cases where a freshly installed listener wants to treat the
+	  current property value as changed from 'unknown' to the actual
+	  value right away.
+
+	  Examples can be found in the Nasal incarnation setlistener(),
+	  where we have for example this (in $FG_ROOT/Nasal/gui.nas):
+
+	    INIT = func {
+		...
+		setlistener("/sim/rendering/fps-display", fpsDisplay);
+		if (getprop("/sim/rendering/fps-display")) {
+		    fgcommand("dialog-show", props.Node.new({"dialog-name":
+	  "fps"}));
+		}
+	    }
+
+	  That is: we first attach a listener that cares for changes to the
+	  FPS display switch, but then we have to manually open the dialog
+	  initially.  That's a duplication of code and could be as simple
+	  as this (INIT part only):
+
+	    INIT = func {
+		...
+		setlistener("/sim/rendering/fps-display", fpsDisplay, 1);
+	    }
+
+	  That is: the optional third arg makes fpsDisplay be called
+	  initially, and then again with every write action. My first
+	  solution was in the Nasal code only, but Andy (rightfully) says
+	  that this should rather be in sg.

+	  just a few split out patches from my zoo of local work ...
+
+	  The patch to simgear-glxproc.diff changes dlopen to not open a
+	  specific library.  If it is used with a NULL argument, we just
+	  get a handle to the current running binary including all loaded
+	  libraries. This has the advantage that we do not rely on the name
+	  of libGL on the specific platform.  Also a user can link with his
+	  own different named libGL or with a static libGL.a
+
+	  Then the render texture again ...
+
+	  glxQueryVersion turns out to return the  minimum of the client
+	  libraries glx version and the servers glx version. *All* Xorg
+	  servers return 1.2 here.  So we never get the glxPBuffer
+	  functions  which are the only ones working with ati's drivers ...
+	   Reverted back to checking the required functions and just use
+	  them if they are there. Still prefering the glx standard variants
+	  since they work on ati's drivers ...

+
+	* simgear/scene/model/: animation.cxx, animation.hxx, model.cxx,
+	  shadowvolume.cxx, shadowvolume.hxx: Harald JOHSEN:
+
+	  Changes =======
+
+	  - shadowvolume.cxx, renderer.cxx :   - reduced the polygon offset
+	  a bit to eliminate some artifact ;   - changed again the cleanup
+	  code for objects inside a tile because it could crash on rare
+	  occasion ;   - the culling of shadow casters has been rewritten
+	  to traverse the scene graph, it should be	a bit faster when
+	  there is a lot of objects ;	- the range selector was not
+	  correctly handled, sometimes the wrong LOD was casting shadows.
+	   - added the option to display aircraft's transparent objects
+	  after the shadows, this will	    reduce the problem of shadows
+	  being hidden by the transparent object (propeller disk,
+	  rotor, etc). A side effect is that aircraft's transparent objects
+	  won't receive shadows      anymore. This is usually a good thing
+	  except when the aircraft use a 'transparent'	    texture where
+	  it should not. A transparent texture in the plib context is a
+	  texture      with an alpha channel or a material with alpha <=
+	  0.99.
+
+	  - model.cxx, animation.cxx, shadowvolume.cxx :   - added an
+	  optional <condition> under the <noshadow> animation
+
+	  - tower.cxx	- correct a rare bug where all occurences of the
+	  aircraft are not deleted from the   departure list causing a
+	  crash in FGTower::CheckDepartureList function.

+
+2005-07-05 20:53  ehofman
+
+	* simgear/scene/model/shadowvolume.cxx: Another update, the

+
+2005-07-05 20:00  ehofman

+	  scene/sky/bbcache.cxx, screen/RenderTexture.cpp:
+	  Harald JOHNSEN:
+
+	  - shadow volume vertex are now shared, using DrawElements instead
+	  of repeated	calls to glVertex, this can improve performance on
+	  some systems.  - added a rendering path that use the alpha
+	  channel instead of the stencill   buffer.  - releasing memory
+	  when tiles objects are destroyed - objects sub parts will not
+	  cast shadows if their name begins with "noshadow"   or if they
+	  are in a <noshadow> animation
+
+	  - bbcache.cxx :    don't ask for a 32 bits context when the
+	  primary context is only 16 bits
+
+	  - RenderTexture.cpp :    corrected a crash when asking for a
+	  second rendering context    on win32 and extensions not being
+	  supported
+
+	  - model.cxx, animation.cxx :	  added a <noshadow> animation,

+
+2005-06-29 11:41  ehofman
+
+	* simgear/props/: props.cxx, props.hxx: Melchior FRANZ:
+
+	  - check for isTied() and refcount has to be made *before* we go
+	  into	 recursion, so as to pertain subtrees of refcounted nodes,
+	  even if there   are no refcounted/tied nodes *in* this tree -
+	  return value inverted, because it's more logical to say

+2005-06-28 13:19  ehofman
+
+	* simgear/props/props_io.cxx: Frederic: Also copy the attributes
+	  over to the new tree.
+
+2005-06-28 13:19  ehofman
+
+	* simgear/props/: props.cxx, props.hxx: Due to a misunderstanding
+	  of what removeChild() actually does, some used it to detach a
+	  subtree from the main tree. The previous patch broke that
+	  behaviour so a new function call detchChild() is now added.
+
+2005-06-27 19:48  ehofman
+
+	* simgear/props/props.cxx: fix return value
+
+2005-06-27 15:49  ehofman
+
+	* simgear/props/: props.cxx, props.hxx: Melchior FRANZ:
+
+	  - introduce removeChildren() and removeChildren(name)  to remove
+	  all children	 or all with a given name - let removeChild() and
+	  removeChildren() also remove child trees, and let them   return a
+	  "dirty" boolean that indicates if one or more subnodes had to be
+	   kept because of refcounting (removeChild returned a
+	  SGPropertyNode_ptr before) - make alias/unalias increase/decrease
+	  the refcounter - don't remove refcounted or tied nodes
+
+	  This patch makes the SGPropertyNode_ptr actually useful. Until
+	  today, they did proper refcounting (except for aliases), but no
+	  other part did check this counter.
+
+	  But SGPropertyNode_ptr aren't only useful for the first time,
+	  they are now highly recommended for every place that relies on a
+	  node address, and wants to "lock" it (so that removeChild(ren)
+	  will never try to remove them). This is not guaranteed for
+	  SGPropertyNode* (and never was). Of course, that's not an
+	  imminent problem, as only four places currently use
+	  removeChild(ren) and these are careful to only remove their own
+	  data.

+
+	  This is the more elegant solution that Andy had proposed in a

+
+	* simgear/scene/model/: animation.cxx, animation.hxx: Melchior
+	  FRANZ:
+
+	  Turn the material animation's <transparency> property into a
+	  group, with members <alpha-prop>/<alpha>, <offset-prop>/<offset>,
+	  <factor-prop>/<factor>, <min>, and <max>. The "material"
+	  animation can now fully replace "blend" and "alpha-test" (-->
+	  <threshold>) animations, with enhanced possibilities: The
+	  "material" animation can be used for one or more explicit objects
+	  (like "blend"), but also for all objects that share one material
+	  (<global>), which avoids problems with objects being forced
+	  together into one tree. Also, an object doesn't have to be
+	  semitransparent or textured with a semitransparent texture to
+	  make blending work. Unlike the "blend" animation, the "material"
+	  animation also makes fully opaque and untextured objects
+	  transparent. (This fixes the bo105's formerly semi-transparent
+	  rotor.)
+
+	  Erik: The blend animation and alpha-test animation are
+	  depreciated as of now.
+
+2005-05-23 18:35  ehofman
+
+	* simgear/scene/model/animation.cxx: Melchior FRANZ:
+
+	  Currently, the material animation sets
+	  glColorMaterial(GL_AMBIENT_AND_DIFFUSE) for all material
+	  properties. This breaks emission-only (e.g. cockpit lighting for
+	  the p51d) or specular-only animation. ==> set glColorMaterial
+	  only where it is really required.

+	  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.

+	  FRANZ:
+
+	  Vivian pointed out that a redefined Ctrl-U key binding didn't
+	  work correctly. I found out that this is, because the definition
+	  in $FG_ROOT/keyboard.xml sets <value type="bool"> for binding[1],
+	  and ... [better sit down first!] ... and assigning <value
+	  type="double"> in a *-set.xml file doesn't *really* set "double"
+	  as new type!
+
+	  Instead, the boolean is kept, and a double sqeezed into it. In
+	  other words: once tainted as bool, you can throw all doubles in
+	  the universe on a property node, and all it will accept is 0 and
+	  1. Without warning!
+
+	  BTW: I changed the patch: I was overly cautious: clear_value()
+	  does already care for ties and for setting NONE, so we just need
+	  to make that public as clearValue(), and use that. Makes the
+	  patch a bit more verbose, though.  :-/

+
+	* simgear/bucket/newbucket.cxx: Phil Cazzola:
+
+	  This is a minor bug fix for sgBucketDiff().  If you crossed the
+	  bucket size boundary, the answer for dx could be wrong.
+
+	  E.g.	 going from   0:0, 21:7  to 0:7, 21:7	would give you dx =
+	  7 (correct)	but going from 0:0, 21:7 to 0:3, 22:0 would give
+	  you dx = 6 (instead of 7)
+
+	  Previously it differenced the center longitudes of the buckets.
+	  When you cross a boundary, the center point of the larger bucket
+	  now lies on the edge of the smaller bucket.
+
+	  The result was a dx with an integer + 1/2 bucket, which rint()
+	  was rounding to the nearest even int.
+
+	  This function only seems to be used in TerraGear.

+
+	* simgear/scene/model/: placementtrans.cxx, placementtrans.hxx:
+	  Mathias:
+
+	  I have done a patch to eliminate the jitter of 3D-objects near
+	  the viewpoint (for example 3D cockpit objects).  The problem is
+	  the roundoff accuracy of the float values used in the scenegraph
+	  together with the transforms of the eyepoint relative to the
+	  scenery center.
+
+	  The solution will be to move the scenery center near the view
+	  point.  This way floats relative accuracy is enough to show a
+	  stable picture.
+
+	  To get that right I have introduced a transform node for the
+	  scenegraph which is responsible for that shift and uses double
+	  values as long as possible.  The scenery subsystem now has a list
+	  of all those transforms required to place objects in the world
+	  and will tell all those transforms that the scenery center has
+	  changed when the set_scenery_center() of the scenery subsystem is
+	  called.  The problem was not solvable by SGModelPlacement and
+	  SGLocation, since not all objects, especially the scenery, are
+	  placed using these classes.
+
+	  The first approach was to have the scenery center exactly at the
+	  eyepoint.  This works well for the cockpit.  But then the ground
+	  jitters a bit below the aircraft. With our default views you
+	  can't see that, but that F-18 has a camera view below the left
+	  engine intake with the nose gear and the ground in its field of
+	  view, here I could see that.	Having the scenery center constant
+	  will still have this roundoff problems, but like it is now too,
+	  the roundoff error here is exactly the same in each frame, so you
+	  will not notice any jitter.
+
+	  The real solution is now to keep the scenery center constant as
+	  long as it is in a ball of 30m radius around the view point. If
+	  the scenery center is outside this ball, just put it at the view
+	  point.
+
+	  As a sideeffect of now beeing able to switch the scenery center
+	  in the whole scenegraph with one function call, I was able to
+	  remove a one half of a problem when switching views, where the
+	  scenery center was far off for one or two frames past switching
+	  from one view to the next. Also included is a fix to the other
+	  half of this problem, where the view position was not yet copied
+	  into a view when it is switched (at least under glut). This was
+	  responsible for the 'Error: ...' messages of the cloud subsystem
+	  when views were switched.

+
+	  - corrected some strange behavior when playing with the render

+	  should play with that - added the choice for texture resolution,
+	  its more comprehensible now (before it was   wrongly allways

+	  now have 64 texture of 64x64, this uses 1Mo of   texture memory
+	  (before it was 20 texture of	256x256, that took more memory and
+	  there was   not enought impostors) - sun vector is now right so
+	  the lighting is a bit better - removed useless sort and light
+	  computations for impostors, this should save a lot of cpu -
+	  blending of distant cloud is more accurate now - clouds are now
+	  positioned correctly, they don't try to escape you anymore - no
+	  more red/white boxes around cloud - textures are now filtered (no
+	  more big pixels)
+
+	  known bugs ==========

+	  to consider. I tried hard, though, to make the animation fast by
+	  only doing the necessary stuff.  It doesn't affect the frame rate
+	  here with my test model. The animation is heavily based on Jim's
+	  "material-emission" animation.
+
+	  * implementation of the "material" animation (this required to
+	  make the   texture path available) + documentation update
+	  ($FG_ROOT/Docs/) * fix some more return values (texture
+	  animations, and select) for the   shadow problem (and some in
+	  anticipation of other problems  :-) * fix compiler warning
+
+2005-03-19 11:19  ehofman
+
+	* simgear/scene/model/animation.cxx: Melchior FRANZ:
+
+	  the cause for the disappearing shadows is, that SimGear doesn't
+	  tell plib to call the pre-traversal-callback function on culled
+	  objects. These calls, however, are necessary to execute the
+	  transform animation that does, for example, translate a shadow
+	  back into the frustum! Curretnly, the callback is only executed,
+	  and the shadow only magically pops up again, when the object
+	  enters the frustum because the view has changed significantly.
+
+	  The plib documentation does only talk about TRUE and FALSE for
+	  possible return values from the pre-traversal-callback. But
+	  src/ssgEntity.cxx reads like this:
+
+	     int ssgEntity::preTravTests ( int *test_needed, int which )
+	     ...
+		 int result = (*preTravCB)(this,which) ;
+
+		 if ( result == 0 ) return FALSE ;
+		 if ( result == 2 ) *test_needed = 0 ;
+	     ...
+
+	  So the return value needs to be 2 to bypass the cull test for
+	  pretraversal, and get the pretraversal in any case. I only
+	  changed the return values in four animations: scale, rotate,
+	  translate, and range, because these are the most likely to move
+	  an object out of the frustum. It's not necessary for
+	  blend/alpha/texture manipulation etc. Of course, this is a bit
+	  more work for plib, but the performance will probably not be
+	  affected, because:
+
+	  * these four animations are mainly used for the aircraft model
+	  (the spin   and billboard (trees!) animations are not affected)
+
+	  * the number of extra nodes to process is quite low
+
+	  * a part of the time spent for the extra nodes to be processed,
+	  was before   used for workarounds that are now not necessary any
+	  more
+
+	  I didn't observe a frame rate drop, at least.

+	  Jim Wilson:
+
+	  This patch adds support to the model animation system for
+	  modifying emissive states on the fly so that it is possible to
+	  make "lights" appear to dimm.
+
+	  This is an example of a configuration entry which should explain
+	  how it is used:
+
+	   <animation>
+	    <type>material-emission</type>
+	    <object-name>Face</object-name>
+	    <property>/controls/lighting/instruments-norm</property>
+	    <emiss-red>1.0</emiss-red>
+	    <emiss-green>0.8</emiss-green>
+	    <emiss-blue>0.5</emiss-blue>
+	   </animation>
+
+	  Note the color entries are the emissive colors when the
+	  "property" value is 1.0.  They are useful for tinting the light.
+	   The "property" itself must be float or double and is clamped to
+	  values between 0 ~ 1.0 inclusively.	The "property" value is
+	  multiplied against the colors to get the actual material
+	  properties.  Thus property value 0.0 = darkest, and 1.0 =
+	  brightest.

+
+	  Trying to find the bug in tower.cxx (that crashes fgfs quite

+	  in the ATC subsystem there will be some other bugs and nitpicking

+
+	  valgrind doesn't like that imgage->tmp is once allocated with new

+
+	  Also, I promised that I'd send patches for "if (foo) delete foo;"
+	  as I'm making other changes to concerned files. texture.cxx is

+	* simgear/props/: props.cxx, props.hxx, props_io.cxx: Melchior
+	  FRANZ:
+
+	  My recent fix for the load/save fgfs.sav feature was a bit too
+	  ambitious.  While aliases lead to abortion before, I tried to
+	  copy them properly, although this wasn't a requirement.
+	  Unfortunately, this seems to have worked for absolute aliases
+	  only, not for relative ones, and hence broke several panel
+	  instruments. The attached patch backs most of the previous patch
+	  out again, and goes a simpler route: just ignore aliases.
+
+2004-12-19 11:19  ehofman
+
+	* simgear/props/: props.cxx, props.hxx, props_io.cxx: Melchior
+	  FRANZ:
+
+	  fgLoadFlight() loads a property file ("fgfs.sav") to a new
+	  property tree, and then copies that over to the main tree.
+	  copyProperties() didn't know how to handle type
+	  SGPropertyNode::ALIAS and hence threw an exception that made fgfs
+	  abort.
+
+	  The attached patch adds support for ALIAS to copyProperties():
+	  aliased nodes are created in the target tree if necessary, and
+	  then linked like in the source tree. It seemed useful to add an
+	  optional argument to props.[ch]xx/getType() that would indeed
+	  return the property type "ALIAS" for aliased nodes, and not the
+	  type of the node that it refers to. The patch also fixes a bug in
+	  writeNode() that caused extra lines after alias entries.
+
+	  If there's resistance to the change to getType() (David?) I can
+	  easily use isAlias(). This just makes copyProperties() a tad
+	  uglier, but I can live with it. It's useful for scanning a tree,
+	  though, if an alias node can be treated exactly like all other
+	  nodes, without automatic redirection.

+	  model/animation.cxx, model/animation.hxx, model/custtrans.cxx,
+	  model/custtrans.hxx, model/flash.cxx, model/flash.hxx,
+	  model/model.cxx: Frederic Bouvier:
+
+	  I was not very happy with the size of the halo, so I created a
+	  new animation to control it. Now we can control the scale value
+	  with the distance from the viewer to the object. The towers are
+	  now beginning to look good. They might need some tuning though.
+	  If you want to play, locate in radio-*.xml this code :
+
+	   <animation>
+	    <type>dist-scale</type>
+	    <object-name>RedLight.2</object-name>
+	    <interpolation>
+	     <entry><ind>0</ind><dep>0.1</dep></entry>
+	     <entry><ind>500</ind><dep>0.3</dep></entry>
+	     <entry><ind>16000</ind><dep>3</dep></entry>
+	    </interpolation>
+	   </animation>
+
+	  You get the idea ? ind is the distance, dep is the resulting
+	  scale value.	The medium tower appears brighter than the tall
+	  one, because the lights are closer to each other. Maybe they need
+	  a smaller scale factor at distance. Feel free to modify these
+	  values if you find a better setup.
+
+	  About the code : I renamed flash to custtrans because the ssg
+	  branch is now less specialized. It needs a callback to compute
+	  the so called 'custom transformation'. It can be used for the
+	  SGFlashAnimation and the new SGDistScaleAnimation. So please cvs
+	  remove flash.[ch]xx and add custtrans.[ch]xx. I also undo some of
+	  the code I send you yesterday that was totally useless. It is
+	  replaced by something simpler and that works.
+
+	  There is also a patch to matmodel.cxx. This is not related and
+	  was something I forgot. Its purpose is to set the alpha test on
+	  material billboard models that are likely to be trees to lessen a
+	  transparency weird effect with clouds.

+
+	* simgear/scene/model/animation.cxx: Frederic Bouvier:
+
+	  I modified the included animation.cxx to have a randomly
+	  displaced time origin, to break the unison. And the flashing
+	  period is also random as you noticed. I also put all the flashing
+	  light of the pole in the same animation so they flash in the same

+
+	* simgear/scene/model/: Makefile.am, animation.cxx, animation.hxx,

+	  Frederic Bouvier:
+
+	  Fix a memory leak, and brownian animation, if not motion.
+
+	  I have 2 new files : personality.[ch]xx . They store the
+	  personality data that would be deleted when the object is
+	  destroyed, instead of staying in the animation maps. I also
+	  manage the current animation step better and the towers are not
+	  flashing randomly now.  Makefile.am is updated.
+
+2004-05-10 16:35  curt
+
+	* simgear/scene/model/: animation.cxx, animation.hxx, flash.cxx,
+	  flash.hxx, modellib.cxx: Frederic Bouvier:
+
+	  modellib.cxx :   Add a branch between the model and its
+	  transformation to add  a unique identifier for the model. I
+	  called it "personality  branch" and it maintains a
+	  "current_object" in SGAnimation.   Animations specifically
+	  written to support it ( currently only   the timed animation )
+	  can add a degree of variety among the   occurrences of the same
+	  model that would look otherwise cloned.
+
+	  flash.[ch]xx :   Better compute the view vector. The flash is now
+	  syncronized with  its axis even at the edge of the screen.
+
+	  animation.[ch]xx :   Lots of changes :  - add a condition to
+	  'rotate', 'spin', 'translate' and 'range'.	When a condition is
+	  specified *and* it evaluates to false, the	animation becomes a
+	  no-op. Possible usage : no rotation during	daylight, LOD range
+	  variable along the day, ...
+
+	   - use different durations for each branch in the timed
+	  animation.
+	    Enable the use of multiple <branch-duration-sec>, one for each
+	    <object-name> specified. Usage : strobes with flash light.
+
+	   - allow randomization of the <branch-duration-sec>, by using
+	    <random><min>_min_value_</min><max>_max_value_</max></random>.
+	    The value computed once is between _min_value_ and _max_value_.
+
+	   - implement model personality in timed animation. If
+	    <use-personality type="bool">true</use-personality> is
+	  specified,
+	    a different set of duration is created for every model in the
+	    scenegraph using this animation. Best if used with
+	  randomization.
+	    When using strobes where the population of the same object is
+	    dense, it avoids the "cheasy" clone effect.
+
+2004-05-08 14:58  ehofman
+
+	* simgear/math/: fastmath.cxx, fastmath.hxx: Add fast functions for

+
+	* simgear/scene/model/: Makefile.am, animation.cxx, animation.hxx,
+	  flash.cxx, flash.hxx, model.cxx: Frederic Bouvier:
+
+	  this patch introduce a new kind of animation and ssg branch.	I
+	  called them flash animation, because they help me to enhance the
+	  look of the rotating beacon and possible future lighthouse. It
+	  computes the cosine of the angle between an arbitrary axis,
+	  transformed by the current modelview matrix, and the view
+	  direction. No trig involved, just a dot/scalar product.
+
+	  The computed value can be modified by three parameters, power,
+	  factor and offset, according to the formulae :
+
+	   value = factor * pow( cosine, power ) + offset.
+
+	  It is clamped between a minimum and a maximum.  This value is
+	  then used as the scale factor of a matrix transformation applied
+	  to the children of the SGFlash branch.
+
+	  The xml syntax, with default values, is :
+
+	  <animation>  <type>flash</type>
+	  <object-name>HaloObject</object-name>  <center>   <x-m>0</x-m>
+	  <y-m>0</y-m>	 <z-m>0</z-m>  </center>  <axis>   <x>0</x>
+	  <y>0</y>   <z>1</z>  </axis>	<power>1</power>
+	  <factor>1</factor>  <offset>0</offset>  <min>0</min>

+	  modified to accept a boolean that will select the proper state:
+	  0/false for bottom, 1/true for top.
+
+	  Then, in SGSky::drawUpperClouds and SGSky::drawLowerClouds,
+	  SGCloudLayer::draw is called with false and true because we see
+	  the bottom of upper clouds and the top of lower clouds.
+
+	  Only overcast has 2 textures, the other types share the same
+	  state for top and bottom, but that could be modified in
+	  SGCloudLayer::rebuild.

+	   model_panel no longer duplicate code.
+
+	   add a pretrav callback to models so that we can
+	   filter out models when calling ssgCullAndDraw on

+	  The message 'Alert: catching up on tile delete queue' comes from

+	  patch is to initialize SGLocation with an invalid position and

+	  timing/sg_time.hxx: Make sky dome scaling values sensible (i.e.
+	  the sky dome will now fill up   the dimensions provided.)  We
+	  draw the sky dome before everything else   and draw it with depth
+	  buffer off so it really doesn't matter, but it just	makes a
+	  little more sense this way.  Updated a few doxygen comments.

+
+	* simgear/scene/model/: animation.cxx, animation.hxx: Add the
+	  ability to include stepped texture translations for things like
+	  digital displays in 3D model animation.
+
+2003-06-08 15:19  ehofman
+
+	* simgear/scene/model/: animation.cxx, animation.hxx, model.cxx:
+	  Jim Wilson: 1. Added support for defining arbitrary rotation axes
+	  using (x1,y1,z1), (x2,y2,z2).  The center is calculated
+	  automatically (midpoint on line) or you may specify an alternate
+	  "center" using the current scheme.  This makes it about  100
+	  times easier to animate flaps, ailerons, etc.
+
+	  2. Added support for plib's ssgTexTrans.  This will allow more
+	  sophisticated 3D instrument features by allowing the texture
+	  mapping itself to be animated. Included function for "texrotate"
+	  and "textranslate".  They configure the same as the geometry,
+	  except the arbitrary axis definition is not necessary (textures
+	  are flat).

+	  IRIX/MipsPro patches from Erik Hofman:
+
+	  This patch adds some missing default ISO C++ headers to SimGear,
+	  especially usefull for Irix/MipsPro. To the best of my knowledge
+	  this only affects the Irix/MipsPro compiler combination although
+	  it might be usefull for others as well.
+
+	  This patch does not yet remove any compiler specific code, but
+	  that would be my next task. The powerfull macros as defined in
+	  the compiler.h file allowed me to split it up into multiple
+	  patches.

+
+	* configure.ac: James Turner:
+
+	  I've had to hack Simgear's configure.ac quite a bit [for Mac OS
+	  X], using the Plib one as a reference.  The basic construct (a
+	  big switch statement based on the target type) is nice, I think,
+	  since it moves lots of IRIX / cygwin / OS-X specialties out of
+	  the way cleanly. Much more re-factoring of the current tests in
+	  configure is possible if people are able to test.
