together -- there's only *one* instrument node now
- don't take "random" tacan, but <tacan-source> from the instrumentation
config (or /instrumentation/tacan[0] by default)
- don't take "random" display-controls from /instrumentation/tacan[0]
- default name is now "radar" (formerly "wxradar")
- re-enable od_gauge ("owner drawn" render-to-texture instruments)
- implement radar in c++ (unlimited number of clouds/ai/mp/... objects,
better performance)
I have corrected a few bugs with the owner draw gauge, weather radar code and heat-haze effect.
- od_gauge.cxx :
corrected a rendering bug where the generated texture was only visible
from a certain angle or distance ;
corrected the search of textures inside the aircraft scene graph ;
- wxRadar.cxx :
the echo of clouds was lost when the pilot was not looking in the
plane direction ;
I had a quick view over the ssgBase::ref() calls in flightgear.
I made them all symmetric and used ssgDeRefDelete to dereference them.
This has the basic advantage that ssgDeRefDelete additionaly deletes the
memory instead of just decrementing the reference cound without deletion ...
This includes an incorrect deref instead of a ssgDeRefDelete in the placement
transform registration I introduced earlier. I believe that this causes the
problems with long flights (unverified, but with a big propability).
Changes
=======
- acmodel.cxx :
we now have an optional new property (/sim/model/texture-path) that is used
as the first path in wich aircraft textures are searched. If textures are not
found there then the usual texture path or model path is used ;
This allows to replace only needed textures for liveries ;
- options.cxx :
added a new --livery=xxx option for the user pleasure ;
this will just set the /sim/model/texture-path property with /livery/xxxx
- od_gauge.cxx, og_gauge.hxx, cockpit.cxx, cockpit.hxx,
generic-instrumentation.xml :
added an helper class that contain a rendering context for glass instrument
or any other opengl drawn instrument ;
- wxradar.cxx, instrument_mgr.cxx, wxradar.hxx :
first experimentation of a weather radar ;
