Hi Sergey,
osg::ref_ptrosgGA::
KeySwitchMatrixManipulator keyswitchManipulator = new
osgGA::KeySwitchMatrixManipulator;
I'm sorry osgGA was from prev version of osg,
now manipulators are attached a bit differently,
I will try to respond today later.
Regards
Sergey
Hi Sergey,
I'm back, actually you were right,
osg::ref_ptrosgGA::KeySwitchMatrixManipulator keyswitchManipulator =
new osgGA::
KeySwitchMatrixManipulato
yes this way add that custom manipulator

is Qt 4.8 already allowing multiple threads to write into one opengl context?
If so it must handle this internal and this might generate some overhead. Also

You can verify this just by running osgViewerQt right away.

I suspect this issue is down to the Scene object being destructed
after the sceneCacheMutex and s_sceneCache are destructed as both of
these are constructed till after the first Scene object is
constructed. To force these objects to be constructed first I think
it is probably best to

Artifacts can be caused by a number of different reasons, as I have
seen the models, screenshots of the artefacts I don't feel comfortable

Hi Sergey,
why don't you use OSGs standard nodetrackermanipulator?
You can track a node and configure which DOF are controllable via the
manipulator.

Thanks Jason,
I understand about the interpolation. I have been operating under the
assumption that if I use a node visitor to loop over each primitive in my
object, create a floatArray of index numbers of size=size(primitive array), and
then bind_per_primitive, then I shouldn't have to worry
Yes, we use GLSL for computing.

Yes, your results do sound different. I'd expect no argument to have green
