Hi,
Hi all,
I have added my new code for far-tiles in a merge request for flightgear and
simgear. You can now test the code, and also check whether texture resizing is
necessary for materials which are not inside the near tiles

I am presenting an experimental (WIP) method to reduce memory consumption by
scenery with 30%, while increasing the visibility distance 4 times.
This method relies on some kind of LOD system, without mesh simplification.

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

OK. So you don't load anything

Surely the normal textures are already loaded by OSG and it's cheaper
just to refer

Hi Mathias,
Ok, for that, I can see a lot of solutions.
Having one that is may be close:
Use the BVH tree that is used in fgelev or fgai. The fgelev one is
parametrized like you probably need today. There is one hacky switch in
17 matches
