I would say, billboarded spherical trees handled as particles.
I don't understand 'particles'.

I haven't noticed any performance degradation (similar to what you
describe) on nVidia hardware.
It sounds like maybe the radeon driver does ok drawing alpha quads (or
quads with an alpha component) from back to front, but perhaps there
is an inefficiency in the pipeline when the alpha

If any of our developers out there are looking for their next project

I've been trying to compile the latest version, but I've encountered some
problems linking against the opengl library.
I'm trying to compile it in windows XP and using:
gcc version 2.95.3-5.
Opengl 1.1.0-6
SimGear 0.0.18
Plib-1.4.2
No problems compiling simgear and plib.
It seems to be caused by a recent change in CygWin. Here is Norman's answer to the
same question:

My guess is that you do not have the Cygwin OpenGL link libraries
installed. Try reruning the Cygwin setup program and make sure
that the
In real life, I've been having a hard time with my landings on the

Practicing with FlightGear has helped a bit, but it didn't really feel

you can practice things like roundout and ground effect operations.
