Hi all,
Similar to the issue I reported (a few weeks ago) of the 'freezes' when
near
other aircraft (which Mathias fixed), here is another similar one.
My build is osg cvs (updated the weekend) using --enable-sdl.
If a prop driven aircraft crashes nose down so the rotating prop gets
embedded
into the ground, FG will 'freeze' and stutter along at 1fps or worse. It
takes ages to gets the menu to react to be allowed to reset (in fact, my
mouse disappears a lot during this time).
One easy way to replicate this is to use the Spitfire on the runway -
ensure
brake lock is on, and open up the throttle - the aircraft will tip over
nose
first, and FG will then show the above problem.
You might want to double check if the console you used for starting up
flightgear is streaming groundcache error/warnings. If it is, running out
of an xterm should have a lower text scrolling load than something like a
gnome terminal window.
At some point we need to patch up the groundcache so it has a bit friendlier
or intelligent failure mode. If it can't see any ground intersection below
the airplane, it might make sense to return the first intersection above the
contact point instead ... then if you do manage to go subterrainian, you
won't get stuck there like what happens now.
