0ad534b55d change update order to fdm -> events -> viewmanager
This removes some jitter in cases where Nasal is used to set up view
parameters from FDM data, such as position and orientation. (The event
subsystem handles Nasal's settimer() calls.)

5123de61ee fix bug that prevented /sim/sceneryloaded from ever becoming "true" if
/sim/screneryloaded-override was "true". At least one subsystem (od_gauge)
waits for /sim/sceneryloaded to bypass CPU intensive code until the scenery
is up. This broke e.g. the RTT-radar when using /sim/screneryloaded-override

--prop:sim/sceneryloaded-override=true has the effect that fgfs
doesn't show the splash screen until the scenery is loaded, but shows
the OTW view (scenery/aircraft) at the earliest possible moment. This is
useful for developers who often need to run fgfs only to check some minor
detail, while not caring about stuttering caused by scenery loading.

(this was the reason why the first two text lines on the splash screen
looked more blurry than the others). BTW: I played with other values

sharper than 0, but not too sharp (and thus flickering).

da6568ad50 Mathias Frhlich:
The new multiplayer patch with an extension to transmit some properties with
the base package. The properties are transmitted in a way that will not
immediately brake the packet format if we need new ones.
Even if the maxmimum number needs to be limited somehow, that format might
work well until we have an improoved packet format which is even more compact
and that does not require to retransmit redundant information with each
packet.

That part is relatively fresh and based on that what Oliver provides on his
multiplayer server web page.

The properties are transferred to the client and I have modified the seahawks
rudder animation property to use a relative property path to verify that it
works appart from the fact that you can see it changing in the property
browser.

The movement is still a bit jerky, but that can be fixed/tuned later without
again braking the packet format.

6bdaa05351 Mathias Frhlich:
This patch limits the maximum simtime we do simulation computations for.
That is highly sensible if you run flightgear in valgrind or some realy slow
debug build. In such a case it is possible that flightgear gets totally
unresponsible, because simulation time might increase slower than real time.
That patch introduces a maximum simulation time per rendered frame to limit
that effect.

If the property /sim/max-simtime-per-frame is set to something strictly
positive, the simulation time is limited to that value.
The default is unchanged - no limit.

Anyway, from the point of view of gui responsiveness and responsiveness to
realtime controls like joystick inputs it might be a good idea to limit that
by default to say 1 second. If you have less than 1fps, flightgear is
unplayable anyway and I believe we do not longer need to care for realtime
correctness for that case ...

029dda3297 In the process of changing, adding and removing files the last few years
there was the situation where four directories contained jst two files,
of which three directories were aircraft related, and one directory contained
test code from Curt that might be better of in SimGear anyhow.

This is just a patch to move a bunch of files to new locations. In case of
local changes to any of them you can do the following:

move replay.[ch]xx from src/Replay to src/Aircraft
move control.[ch]xx from src/Control to src/Aircraft
move ssgEntityArray.[ch]xx from src/Objects to simgear/screen

In addition it has been decided only to use .[ch]xx files in all directories
unless it's contained within an FDM specific directory, in which case the
author is free to do whatever (s)he wants.

In this repspect the following files have been renamed in src/Multiplayer:

tiny_xdr.[ch]pp has become tiny_xdr.[ch]xx
multiplaymgr.[ch]pp has become multiplaymgr.[ch]xx

7b824755ee Mathias Frhlich:
I have prepared a patch that:
- Introduces a FGTileMgr::scenery_available method which asks the tilemanager
  if scenery for a given range around a lat/lon pair is already loaded and make
  use of that method at some -9999 meter checks.
- Introduces a FGScenery::get_elevation_m method which queries the altitude at
  a given position. In constrast to the groundcache functions this is the best
  choice if you ask for one *single* altitude value. Make use of that thing in
  AI/ATC classes and for the current views ground level. At the current views
  part the groundcache is reused if possible.
- The computation of the 'current groundlevel' is no longer done on the
  tilemanagers update since the required functions are now better seperated.

Alltogether it eliminates somehow redundant terrain level computations which
are now superseeded by that more finegrained functions and the existence of
the groundcache. Additionally it introduces an api to commonly required
functions which was very complex to do prevously.

4c10ef139c 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.

I implemented the method pointed out by Norman. It works great on windows and saves me a lot of CPU cycles. This way, I can get the same framerate in moderately populated areas and have CPU idle 50% of the time instead of wildly looping in the NVidia driver while waiting to sync on vblank.

It has been tested on Linux by Melchior. He saw the same gain in CPU cycles.

634e79353f Roy Vegard Ovesen:
I've finished the emigration of the radiostack, and I've also removed it
completely. It turned out that the comm radio is completely implemented in
the ATC subsystem. I've changed the affected ATC files to point
to /instrumentation/com, but I guess that the maintainer of the ATC code
should decide wether to make it configureable, and how.

I also had to change some files in Network and Main. The changes in network
should be obvious, but the changes in Main were a bit suspect. The files
included radiostack.hxx, but they weren't directly depending on
radiostack-hxx. They were depending on other files that were included by
radiostack.hxx. I got it to compile, but I'm not sure if I included the
correct directly depending file.

For the data directory I changed every occurrence of /radios/
with /instrumentation/ with this simple one-liner that I found on the net:

find -name '*.xml' -type f | xargs perl -pi -e
's/\/radios\//\/instrumentation\//g'

Instead of me sending all the files that got changed by this I suggest that
you execute the one-liner yourself. Of course I can not guarantee that this
will work perfectly, but I considered hand editing to be not an option (I'm
lazy). I don't want to test every aircraft to see if everything still works,
I think it's better to wait and see if anyone complaints about broken nav
radios/instruments.

986492d72d Finish what was committed in a broken state yesterday.
Split up main.cxx into a program manegement part (which remains in
main.cxx) and a render part (the new renderer.?xx files). Also turn
the renderer into a small class of it's own. At this time not really
exctining because most of the stuff is still global, but it allows us
to slowly migrate some of the global definitions into the new class.

The FGRenderer class is now managed by globals, so to get the renderer
just call gloabals->get_renderer()

At some pijt it might be a good idea to also turn the remaining code in
main into a class of it's own. With a bit of luck we end up with a more
robust, and better maintainable code.

dba02e35d4 Frederic Bouvier:
FG_ENABLE_MULTIPASS_CLOUDS must be defined to enable
 the algorithm. I made this because the stencil buffer
 must be initialized at the beginning of the program and
 OpenGL can fallback to software rendering if it can't
 find a visual with stencil buffer. I didn't touch the
 configure script, so CXXFLAGS=-DFG_ENABLE_MULTIPASS_CLOUDS
 must be set before running ./configure.

 If FG_ENABLE_MULTIPASS_CLOUDS is defined, the main render
 loop begins by reading the /sim/rendering/multi-pass-clouds
 property. It is a boolean property so there are only two
 quality levels. false means no multi pass and no use of
 the stencil buffer, true means an additionnal pass for
 both upper and lower cloud layers.

 The algorithms are as follow :
  /sim/rendering/multi-pass-clouds=false
   1. draw sky dome
   2. draw terrain only
   3. draw clouds above the viewer
   4. draw models except the aircraft
   5. draw clouds below the viewer
   6. draw the aircraft.
  The cloud rendering doesn't update the depth buffer.
  This means that models overwrite clouds above the viewer.
  This is only noticeable for tall buildings and when
  flying very low. Also, drawing low clouds after models
  means that they are not blended with models' translucent
  surfaces. Large transparent area require alpha test
  enabled and AI aircraft canopy are making holes. The
  pilot's aircraft being rendered at the end, there is no
  problem with canopy or prop disc.

  /sim/rendering/multi-pass-clouds=true
   1. draw the sky dome
   2. draw the terrain only
   3. draw all clouds
   4. draw models except the aircraft
   5. redraw the clouds where the models where drawn ( stencil
      test on )
   6. draw the aircraft
  The assumptions made by this algoritm are that the terrain
  is not transparent ( should be true in all cases and
  that there are no clouds between the aircraft and the viewer.
  Assuming these facts, there should be no blending bugs.

  The screenshot rendering is not updated yet.

This patch is there to correct a problem that prevent to load static objects when specifying a relative fg-root or a different, relative, fg-scenery. It appears that there is a mix between fg-root, fg-scenery and PLIB's model-dir.
It has been reported on the list that users are not able to see the buildings, especially those running the win32 builds because they run 'runfgfs.bat' that set FG_ROOT=./DATA.

I decided not to use model-dir because it just add confusion and to build a valid path earlier.

9c0c54ef6c Implimented a simple frame rate throttle.
Normally for smoothest frame rates you would configure to sync
to your monitor's vertical refresh signal.  This is card/platform
dependent ... for instance with Linux/Nvidia there is
an environment variable you can set to enable this feature.

However, if your monitor is refreshing at 60hz and you can't quite sustain
that with flightgear, you can get smoother frame rates by artificially
throttling yourself to 30hz.  Note that once you are about about 24fps, it
is *change* or inconsistancy in frame rate that leads to percieved jerkiness.

You want to do whole divisors of your monitor refresh rate, so if your
display is syncing at 75 hz, you might want to try throttling to 25 hz.

18dec3596d Curtis found another inconsistency in the sky repaint check. I am afraid that adding more checks would eventually give the same framerate as repainting every frame. Consider this a failed experiment. 2003-05-07 15:53:50 +00:00

2119db35c3 This is step "1" of probably "many" in the process of separating out the
scene management code and organizing it within simgear.  My strategy is
to identify the code I want to move, and break it's direct flightgear
dependencies.  Then it will be free to move over into the simgear package.

- Moved some property specific code into simgear/props/
- Split out the condition code from fgfs/src/Main/fg_props and put it
  in it's own source file in simgear/props/
- Created a scene subdirectory for scenery, model, and material property
  related code.
- Moved location.[ch]xx into simgear/scene/model/
- The location and condition code had dependencies on flightgear's global
  state (all the globals-> stuff, the flightgear property tree, etc.)  SimGear
  code can't depend on it so that data has to be passed as parameters to the
  functions/methods/constructors.
- This need to pass data as function parameters had a dramatic cascading
  effect throughout the FlightGear code.

This is just a port of an old 3D HUD patch to the new view code.
This pans the HUD with the view, by pasting it onto a quad fixed in front of the viewer.  It also fixes the awful, arbitrary scaling problems the HUD code has.  The old HUD only looks right when viewed at 1024x768 and 55 degree FOV.  This works the scale out magically so that it looks right in all views.  It also redefines the "<compression-factor>" tag in the ladder to (1) mean compression instead of expansion and (2) have non-psychopathic units (now "1" means 1 degree per degree).  Fix this in your existing HUD ladder files before reporting bugs.  It's definitely a cosmetic win -- the velocity vector points at the right thing and the horizon lines up properly.

98dca16794 Having the runway lights "pop" in at a specific range is not 100% realistic.
I have updated the lighting code to use fog to try to fade the runway lights
in smoothly, but still keep them from being visible until you are about 7-10
miles out, and then only have them be very faint at first.  I think what I
have is a bit nicer than before since it completely avoids the "popping" effect,
but I've very open to tweaking the actual ranges based on people's real

52312f2a13 Restructuring some of the initialization code.
The general idea is to help clean up some aspects of the FDM init and be
able to provide startup conditions in a less ambiguous manner.

Previously, things like positions, orientations, and velocites were set on
"the bus".  These had to be read by the FDMs which then were supposed to
initialized themselves to those values and turn write around and start
modifying those values.  It was messy and cumbersome.

Now, all the initial fdm conditions are written to a sub-[property-]tree
under /sim/presets/

The values in /sim/presets/ always stay set to what the user has specified.
The user can change these at his/her liesure, and then request a "reset"
which will reset to the new conditions.  I don't even want to say how this
worked before. :-)

Now, an script, or gui interface can stage a set of initial conditions while
the sim is running (without disrupting it), and then call "reset" to commit
the change.

People who should worry about all this are FDM writters, and a small few
others who care about over all program structure and flow.

72017fc671 Andy Ross:
The biggest and coolest patch adds mouse sensitivity to the 3D
cockpits, so we can finally work the radios.  This ended up requiring
significant modifications outside of the 3D cockpit code.  Stuff folks
will want to look at:

+ The list of all "3D" cockpits is stored statically in the
   panelnode.cxx file.  This is clumsy, and won't migrate well to a
   multiple-aircraft feature.  Really, there should be a per-model list
   of 3D panels, but I couldn't find a clean place to put this.  The
   only handle you get back after parsing a model is a generic ssg
   node, to which I obviously can't add panel-specific methods.

+ The aircraft model is parsed *very* early in the initialization
   order.  Earlier, in fact, than the static list of allowable command
   bindings is built in fgInitCommands().  This is bad, as it means
   that mouse bindings on the instruments can't work yet.  I moved the
   call to fgInitCommands, but someone should look carefully to see
   that I picked the right place.  There's a lot of initialization
   code, and I got a little lost in there... :)

+ I added yet another "update" hook to the fgRenderFrame routine to
   hook the updates for the 3D panels.  This is only required for
   "mouse press delay", and it's a fairly clumsy mechanism based on
   frame rate instead of real time.  There appears to be delay handling
   already in place in the Input stuff, and there's a discussion going
   on about different mouse behavior right now.  Maybe this is a good
   time to unify these two (now three) approaches?

c162577340 Begin work on rendering runway lights using environment maps. The basics
are now working.  A runway light is defined by a point and a direction.  The
point and direction are combined with the local up vector to create a small
triangle orthogonal to the direction.  The two ficticous corners of the
triangle are given an alpha value of zero, the orignal corner is given an
alpha of one.  The triangle is drawn in glPolygonMode(GL_FRONT, GL_POINT)
mode which means only the corner points are drawn, and since two have alpha=0
only the original point is drawn.  This is a long way to go to draw a point,
but it ensures that the point is only visible within 90 degrees of the light
direction, behind the light it is not visible.  This is still a long way
to get to drawing a point, but we use an environement map, with the direction
vector as the normal to mimic a light that is brightest when viewed head
on and dimmest when viewed perpendicularly or disappears when viewed from
behind.

- warning, there is a bug in how the current runway light direction vector
  is calculated which will adversely effect runway lighting.  The airports
  should be regenerated in order to fix this problem.

df6989a37a Bernie Bright:
Here is a FGIO class derived from FGSubsystem that replaces the fgIOInit()
and fgIOProcess() functions.  The FGIO::update(double delta) doesn't use the
delta argument yet.  I suspect it could be used as a replacement for the
calculated interval value but I'm not familiar enough with that piece of code
just yet.

I've also added two "command properties" to fg_commands.cxx that select the
next or previous view.  Writing any value to these properties triggers the
corresponding action.  As an example I modified my keyboard.xml:

 <key n="118">
  <name>v</name>
  <desc>Next view</desc>
  <binding>
   <command>property-assign</command>
   <property>/command/view/next</property>

  <binding>
   <command>property-assign</command>
   <property>/command/view/prev</property>
   <value type="bool">true</value>

Animations are now contained within the scene graph itself and are

to be used for static objects and random objects as well.

Added new FGModelLoader and FGTextureLoader classes.  These are intern
tables for models, to guarantee (mostly) that no model is loaded more
than once.  FGTextureLoader is not yet used anywhere, but
FGModelLoader is now in place everywhere that ssgLoad* used to be
used (thus adding the ability to use animations).

In the future, FGModelLoader will add some interesting functionality,
including the ability to reload 3D models on the fly.
