ssgSetNearFar(). This by default creates a symmetric view frustum which is
typically what an application wants.
However, to get control of the view frustum in order to build support for
asymmetric view frustums, we need to wrap these calls with a bit of our own
logic.
This set of changes wraps all calls to ssgSetFOV() and ssgSetNearFar() with
FGRenderer methods.
I also standardized how the FGRenderer class is handled in globals.[ch]xx.
This led to some cascading changes in a variety of source files.
As I was working my way through the changes, I fixed a few warnings along
the way.
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.
systems. Fix a couple bugs/oversights.
- atc610x.cxx: Much code has moved into the configurable input mapper
(ATC-Inputs.cxx) and the remaining input massaging code has moved into
the atcsim.nas module.
- We need to be able to support a per engine master bat/alt switch.
- Forgot to write the gear level state into the network structure.
native_fdm:
- renamed EGT->egt for consistancy.
- added manifold pressure to the structure.
null space without killing the engine (hardware specific problem.)
- NMEA output: I'm slightly confused but it appears that a real GPS outputs
traditional unix line endings on it's gps strings, we were outputing DOS
CR/LF which was causing some confusion. This changes the line ending
convention to match that of a real gps.
- Calculate true ground track and speed for NMEA.
I just met a couple of warnings about depricated headers beeng used.
Please take a look at patch (against today cvs) attached wich
does strstream -> stringstream migration. I hope you found it usefull.
latest version is attached to reduce need to search property
tree each frame. I don't think this will break any Fg code and
opengc has been updated a while back and have had no complaints ;-) so it
should be a no impact change, hopefully.
controls in the cockpit vs. which wheels they apply to. FlightGear now
sets /controls/gear/brake-left, /controls/gear/brake-right, and
/controls/gear/brake-parking. It should be up to the FDM to sort out
which wheels under which circumstances are affected by these controls
and ultimately what happens to the physical motion of the aircraft.
net_ctrls.hxx net_fdm.hxx net_fdm_mini.hxx net_gui.hxx
I, Curtis Olson, being the primary author of these header files, hereby
release them into the public domain to facilitate interfacing FlightGear
with other external code (which might need to remain proprietary or may
be licensed under some not quite GPL compatible terms.)
I have added a fledgling replay system that records flight data and control
positions during the flight.
I have added an internal command called "replay" which will trigger a replay
of the entire saved flight data set. This could be bound to a keyboard or
menu command, in fact this entire module is screaming for someone to build
a gui to control playback speed, amount of playback, etc.
This is the initial version so there are kinks that still need to be worked
out, please be patient.
Square the normalized direction acceleration for the y and z axes, so
that turbulence predominantly affects pitch.
Bind to the /environment/turbulence/magnitude-norm and
/environment/turbulence/rate-hz properties in FlightGear.
clarity:
nav_radial => nav_target_radial (same as selected, except for a LOC)
nav_heading => nav_reciprocal_radial
nav_magvar => nav_twist (it's not always the same as magvar)
nav_heading_needle_deflection => nav_cdi_deflection
nav_gs_needle_deflection => nav_gs_deflection
Added nav_radial back in, but now it shows the current radial from the
VOR, as one would expect. This value also appears in the
/radios/nav[*]/radials/actual-deg property.
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.
