Hi All,
While I hesitate to claim performance improvements I've not seen myself,
it may be that this was caused by this commit:
266b362238d0cef5a1c4df81bacbe941ee4c59ef
which discards transparent fragments. I'd be very interested if you could
revert the changes in that commit and let me know if

OK. So you don't load anything

Hi everybody,
I just had the chance to compile a recent git-pull on my old and
battered linux-notebook workhorse and with great delight, I noticed that
I can run FlightGear again with 26fps at KSFO. I had to strip down most
eye candy shaders for the GeForce Go 7400 but 3D clouds render fine

Hi Mathias,
It's actually nothing really special about it, I'm just modifying a littl
There are many issues and tradeoffs with mesh simplification. There are
many algorithms and approaches, each with their own unique strengths and
weaknesses. Challenges include finding a strategy to hide the cracks

Hi Adrian,
The same idea is behind the osg lod based whole world model.
Where do you store the elevation data?
