I just noticed some mistakes in my original post: DrawHandler should be
DrawCallback, and NodeHandler should be NodeCallback. Sorry about that.
I'm writing the emails on one machine and reading from another, and
I've got some results.
Cheers,

Hi all,
I was wondering if anyone can make some suggestions as to resources that
are useful for learning GLSL in modern OpenGL (say, 3.0+) with a

and mostly dates back to the early days

In OpenSceneGraph 3.0.1, is there a known fundamental incompatibility

started to work in osgEphemeris in order to provide a more interesting

overkill for that.
You probably still have to consider the culling problems introduced by
skydomes (a scene with a skydome is artificially big).

multi-texturing, transparency, fog, etc...
I exclude the skydome of osgephemeris from culling (cf thread) and
disable depth test on it.
VDSM works quite well for non human-like viewpoints (near the ground,
looking towards horizon).
