Hi all
I have quad core system with single GPU of nVidia Geforce 6600.
Having dual x-server configuration and I have osg-2.0.
When I run osgviewer and toggles the statistics by pressing key 's'
program crashes.
Is this known bug?
Thanks

So far i have had no success.

Hi Pawan,
A node's local bounding sphere encompasses the subgraph below the
node, and in the coordinate frame of the subgraph below the node, it's
not at all affected by what happens above it in the scene graph. The
basic feature of scene graphs.

Hi Santosh,
I don't recall this happening in 2.0, but I tended to test it with
dual graphics cards and multi-core. I suspect you configuration is
quite unusual.
Could you please upgrade to 2.2 to 2.3.x and let me know if the
problem still exists.
Robert.

Hi all,
osgdem behaves rather strangely (svn, windows).
As soon as I specify a --cs option on the command line, the generated

I've tried to use the same --cs string both for input and ouptut, but
result is the same: no z component.

Hi Pawan,
The OSG has view frustum culling built into it so you should need to
add anything extra. You can also just configure the viewer's Camera
so that their view frustum all just map to the various
projector/monitors.

The OSG's old blue marble example was removed well over a year ago,
what version are you using?
Could you back and say what you are trying to do/learn to do, there is

The osghangglide has a basic skydome, and the osgvertexprogram has a
