- Removed some old cruft.
- Removed some support for older versions of automake which technically was
correct, but caused the newer automakes to squawk warnings during an
initial sanity check (which isn't done very intelligently.)
NOTE: this fix is technically not correct for older version of automake.
These older version use the variable "INCLUDES" internally and could have
them already set to an important value. That is why we were appending
our values to them. However, newer versions of automake don't set this
value themselves so it is an error to append to a non-existant variable.
We seem to "get away" with overwriting the value on older versions of
automake, but if you have problems, consider upgrading to at least
automake-1.5.
- tidies up the update-time-step handling (making it a simple "dt");
- makes the altimeter get a proper pressure, and the (unused) vacuum
calculation get a proper RPM (*);
- replaces property name look-ups with static pointers to property nodes.
Notes from DPM:
- the static pointers are a very bad idea, but they're only temporary;
I plan to make FGSteam into a proper subsystem soon, and then they
can be member variables
- I fixed the patch to get the current static pressure from the
/environment/pressure-inhg property, so that the altimeter interacts
properly with FGEnvironment
+ The panel(s) are now an first-class SSG node inside the aircraft
scene graph. There's a little code added to model.cxx to handle the
parsing, but most of the changes are inside the new FGPanelNode
class (Model/panelnode.[ch]xx).
+ The old FGPanel source changed a lot, but mostly cosmetically. The
virtual-cockpit code moved out into FGPanelNode, and the core
rendering has been abstracted into a draw() method that doesn't try
to set any OpenGL state. I also replaced the old inter-layer offset
code with glPolygonOffset, as calculating the right Z values is hard
across the funky modelview matrix I need to use. The older virtual
panel code got away with it by disabling depth test, thus the "panel
draws on top of yoke" bug. PolygonOffset is really the appropriate
solution for this sort of task anyway.
+ The /sim/virtual-cockpit property is no more. The 2D panels are
still specified in the -set.xml file, but 3D panels are part of the
model file.
+ You can have as many 3D panels as you like.
Problems:
+ The mouse support isn't ready yet, so the 3D panels still aren't
interactive. Soon to come.
+ Being part of the same scene graph as the model, the 3D panels now
"jitter" in exactly the same way. While this makes the jitter of
the attitude gyro less noticeable, it's still *very* noticeable and
annoying. I looked hard for this, and am at this point convinced
that the problem is with the two orientation computations. We have
one in FGLocation that is used by the model code, and one in
FGViewer that is used at the top of the scene graph. My suspicion
is that they don't agree exactly, so the final orientation matrix is
the right answer plus the difference. I did rule out the FDMs
though. None of them show more than about 0.0001 degree of
orientation change between frames for a stopped aircraft. That's
within an order of magnitude of what you'd expect for the
orientation change due to the rotation of the earth (which we don't
model -- I cite it only as evidence of how small this is); far, far
less than one pixel on the screen.
[and later]
OK, this is fixed by the attached panel.cxx file. What's happened is
that the winding order for the text layer's polygons is wrong, so I
reverse it before drawing. That's largely a hatchet job to make
things work for now, though. We should figure out why the winding
order is wrong for only text layers and fix it. I checked the plib
sources -- they're definitely doing things CCW, as is all the rest of
the panel code.
Odd. I'm also not sure why the 2D panel doesn't care (it works in
both winding orders). But this will allow you to check in working
code, anyway. There's a big comment to this effect in there.
- changed FGSubsystem::update(int) to
FGSubsystem::update(delta_time_sec); the argument is now delta time
in seconds rather than milliseconds
- added FGSubsystem::suspend(), FGSubsystem::suspend(bool),
FGSubsystem::resume(), and FGSubsystem::is_suspended(), all with
default implementations; is_suspended takes account of the master
freeze as well as the subsystem's individual suspended state
- the FDMs now use the delta time argument the same as the rest of
FlightGear; formerly, main.cxx made a special case and passed a
multiloop argument
- FDMs now calculate multiloop internally instead of relying on
main.cxx
There are probably some problems -- I've done basic testing with the
major FDMs and subsystems, but we'll probably need a few weeks to
sniff out bugs.
The FlightGear patch is to take account the change in the getChildren
function that now returns a vector<SGPropertyNode_ptr>. If the
removeChild functionnality is to be added in FlightGear, all those
SGPropertyNode * floating around should be changed to
SGPropertyNode_ptr.
This led to an investigation into why the ident playing didn't work anymore.
Recent changes in the sound manager broke some assumptions the radiostack
code was making. These patches should hopefully fix all that back up.
Erik, please review these changes to double check I didn't do more damage
than good. :-)
Here are the Boost-less FGEventMgr updates I promised.
Removed Boost dependencies from FGEventMgr.
Removed Boost configure check.
fgMethodCallback now handles const member functions.
I've successfully tested these changes with gcc and msvc.
This patch moves built-in Class (for now only mag-ribbon) into special
directory as you have written it in TODO: in comments of this class in
panel_io.cxx. IMHO it is good idea. I want to play with built-in
classes and OpenGC and this will be useful.
radiostack.cxx, fg_init.cxx and main.cxx. If these changes are accepted
then you can remove Time/event.[ch]xx and Include/fg_callback.hxx from
the repository.
radiostack.cxx:703 says
bool light_on = ( outer_blink || middle_blink || inner_blink );
but none of the flags has ever been initialized when this line is first
executed.
as a follow-up of my previous message, I found that in panel.cxx, function
const char *FGTextLayer::Chunk::getValue () const, there is the use of a
member variable _buf that seems to be uninitialized.
(mainly in src/Input/input.cxx) will make src/GUI/mouse.cxx obsolete
and bring the mouse into the same input system as the joystick and
keyboard. This is just preliminary work allowing, covering mouse
clicks (no motion yet), and it actually crashes on a middle or right
click.
The new mouse support is disabled by default until it become stable;
to try it out, you need to configure --with-new-mouse.
