separate header file. This change will help integrate properties into
JSBSim.
Also, I (David Megginson) removed most of the SimGear include
statements from globals.hxx, reducing the amount of recompilation
every time SimGear changes. This required making minor changes to a
lot of files that were depending on the side-effects of the inclusions
in globals.hxx.
- implement the standard FGSubsystem interface, for consistency
- eliminate current_autopilot and add get/set_autopilot to FGGlobals,
for consistency
- use private methods rather than static functions for tying
properties
There should be no change in functionality.
is a work in progress and needs severe enhancement before it will be
useful. It provides a UDP data channel that goes both ways between
flightgear and the fdm. It also provides a TCP 'command' channel so
flightgear can 'reliably' send commands to the remote fdm (such as set
starting position, reset on ground, etc.)
includes the ability to specify per vertex normals rather than depending
the normals list being the same as the vertices list. (Support for
previous binary file format scenery is maintained.)
This seems to pretty much correct the problem. Part of the problem is that
rotations are occuring at the firewall (model origin) which seems a little
un-natural inside the cockpit. The rest of the problem is I am just learning
how this stuff works (I know I've been saying this for a couple months
now...but hey I'm slow :-)).
* Add new trigger types: raise, fall
* Add new trigger offset parameter
* Add new volume/pitch types: inv, abs, sqrt
* Add initial support for multiple events to intervere in a single sound
(by using the same name, see the crank section of 172-sound.xml)
* Cached the volume/pitch type fucntions
(No more if's inside the loops in update())
created a new class, FGViewPoint (declared in viewer.hxx) that holds a
single position in FlightGear coordinates, and have used it to factor
a lot of the common code out of viewer_lookat.cxx and viewer_rph.cxx.
I don't know whether this new class will stay or not; it might just be
a temporary step, or it might end up taking over much of the current
viewer functionality. It would be a bad idea to code against it right
now.
plane to 0.2; otherwise, use the old defaults.
This is a temporary step that will allow me to work on a 3D cockpit
without breaking current behaviour; the final approach will be to put
the 3D model in its own scene graph, with different clipping plane.
OK, attached is a replacement for mouse.cxx that works the view using
the view-offset/tilt interface, rather than the (kinda odd) GuiQuat
stuff. It's kind of a hack job, as I left the hooks to GuiQuat in in
other places for fear of breaking something. Still, it removed more
code from mouse.cxx than it added, which has to count for some
elegance points.
Oh yeah, I forgot to send that one along. This one is my bug, I
goofed the precedence in the fgPanelVisible() function in panel.cxx
such that the panel was *always* visible if virtual cockpit was
enabled. Here's a replacement. I've modified the style from a single
boolean expression to an if-list, since that's more readable to my
eyes for expressions this big:
and soon to be renamed) is true, FlightGear will draw the 3-D model
even in internal view. This makes sense right now only with the C310
model, since the others don't have any kind of interiors modeled and
all surfaces in all models are one-sided.
This isn't quite working yet -- the view code is very hard to
disentangle, and currently, if the view is not forward, roll and pitch
are applied incorrectly. It looks interesting (modulo a messy model)
on the ground, in level flight, or looking straight ahead under any
other flight conditions.
to 10m after takeoff, but that doesn't really make sense any more,
especially if models are going to have interior views. Is there any
real saving in pushing the near plane out anyway?
was some confusion between degrees and radians which would lead to a huge
goal_view_offset value. The display would sit and spin for a *long* time
trying to wind it's way up to this large value.
difference between the two is this: A sample is file related and sound
is a authonomus entity. This means you can have several sounds pointing
to a single sample. In that case, just one sample is loaded into memory.
The advantage is you can play the same sample with different pitch or
volume, but with just one sample loaded into memory.
To fully support this there is a new fucntion call:
FGSimpleSound *sample = new FGSimpleSound("filename");
mgr->add(sample, "name");
should be replaced by:
FGSimpleSound *sample = mgr->add("name", "filename");
But the old behaviour is still supported with one minor change, sounds
with the same name aren't supported anymore.

Actually, I think I'm off the hook here; the problem is pre-existing.
What's happening is that the x/y offsets enter the modelview matrix at
line 346 in the current panel.cxx. But note that the same
transformation also occurs before each instrument rendered at line
403. What's happening is that the instruments are double-translated
relative to the background.
Unless I'm not understanding something, the one inside the instrument
render loop looks unnecessary. Removing it fixes the issue and
doesn't cause any bugs that I can find. It also fixes a bug where you
could scroll the instruments on top of the 3D panel, where the offsets
are supposed to be ignored. :)
Attached is a new panel.cxx which fixes that bug, and substantially
simplifies the virtual panel code (the matrix inversion that I thought
was needed wasn't, but there were some offsetting scale bugs that hid
the problem).
