This is a patch to make display list usage optional. They are on by default.
Use --prop:/sim/rendering/use-display-list=false to use immediate mode.
There is also a change in exception handling in main.cxx and bootstrap.cxx

f614545fc5 Roy Vegard Ovesen:
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.

fa7f2468c2 Roy Vegard Ovesen:
I've added some digital filters to the autopilot. They are all low-pass
filters that filter away high frequency signals/noise. There are 4 different
filters:

1. Exponential - The algorithm is essentially the same as the one used in the
   fgGetLowPass() function.

2. Double exponential - Two exponential filters in series. This filter has a
   "steeper" frequency response curve. It filters "better" than the single
   exponential.

3. Moving average - Averages a number of inputs.

4. Noise spike - limits the amount that the output value can change from one
   sample to the next.

Filters 1 and 2 are characterised by it's filter-time in seconds. For filter 3
you have to set the number of input samples to average over. For filter 4 you
set the maximum allowed rate of change as [1/s]. Since the sampling interval
(dt) isn't constant we have to calculate the maximum allowed change for every
update.

Example of a double exponential filter with filter time 0.1 seconds, that is
1/0.1 = 10 Hz.

  <filter>
    <name>pressure-rate-filter</name>
    <debug>true</debug>
    <type>double-exponential</type>
    <input>/autopilot/internal/pressure-rate</input>
    <output>/autopilot/internal/filtered-pressure-rate</output>
    <filter-time>0.1</filter-time>
  </filter>

This would go in the autopilot configuration file.

I've also removed the filtering of the "pressure-rate" helper value, use the
new filters if you want to filter it!  ;-)

As I had reported on 2004/8/4 00:02:56 ("yasim + bo105 + vrp + @#%$#@ == argh!")
there must be a bug somewhere in YASim, which is responsible for the Bo105
turning around the FDM origin (nose tip) rather than the CG. Some people assumed
that I was just another victim of the "view offset" illusion, but this wasn't
and isn't the case.

Maik Justus (the rotor man) has now supposedly found the bug in YASim[1].
Look at this code in FDM/YASim/Integrator.cpp:35--66:

41e217fb9a Continued work to clean up the hires screen shot code and move it back towards
a working state.  I still see an anomoly when taking a screen shot from inside
a 3d cockpit, but external (chase/tower) views seem to work well.  I also
added a property to control how many screen-res tiles are generated in the
output.  Theoretically, you can now generate unlimited resolution screen shots,
or limited only by your disk space and patience.

Today I successfully generated a 20*1024 x 20*768 (20480x15360) resolution
screen shot.  If you rendered that at 100 dpi it would cover a poster of
about 17 feet by 12.8 feet.

Good luck trying to display something that big or convert it to anything
useful on a typical PC. :-)

fcb67de4f5 Restore trRenderFrame (which used to be in main.cxx before the
split).  If SimGear is configured --with-jpeg-factory, then FlightGear
will fail to build unless this function is present.

FIXME: this is very messy architecturally -- find a better solution,
like passing this explicitly as a callback to the libJPEG class
(SimGear should not have a dependency on FlightGear).

I've made appropriate changes to Readme.submodels to reflect the
variation of Cd with Mach number.

Spitfire.submodel has been changed to use the variation of Cd with Mach
number

Submodel.cxx has been changed so that the default value of Cd is the
subsonic Cd of a non-boat tailed bullet.

I've finished the variation of Cd with Mach number.
The calculations are only applicable to ballistic
objects, and then strictly one shape: non boat-tailed bullets/shells, so
I've put them in AIBallistic rather than AIBAase. For all inputs, Cd
should be the sub-sonic value, so bullets will need changing.

I've just posted a graphical analysis here:

328053fe23 Vivian Meazza:
The calculation of submodel mass from weight has been moved from AIBallistic
to Submodel so that it is calculated only once, rather than on every
iteration as a present. The parameter <contents> has been added, primarily
so that droptanks will have the proper mass. It is the path to an
appropriate property containing a weight in lbs.

Care has to be taken with the use of <contents> because after a reset there
appears to be a delay in submodel instantiation (dt not properly reset???)
and the weight property is not always picked up before it is set to zero in
the key bindings. Slightly hard to explain. It works fine if FGFS has not
been reset though. There is a partial solution which involves the rejigging
of the fuel and gui nasal scripts, but there is still the visible delay in
instantiation to be resolved. I've nearly done the nasal fixes, which will
form part of an update to the Hunter only. I'll probably complete those
later today.

The value of rho (air density) varies with height. (Including the upper
stratosphere, ust in case someone wants to model ICBMs.) The standard
atmosphere is used (based on a sea-level temperature of 15 deg C.).

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.
