You could use a callback on the transform from the hand to update the
transform on the other node. The other way is to position the other
node under the hand in the hierarchy. The transforms of the other node
then become relative to the hand. You'd need to convert local to world

Hi Robert, hi everyone,

strictly optional feature that would not be included in precompiled packages.

Hi Forest,
The GPU draw time is the time that all OpenGL commands take to run
down on the GPU. If your application is GPU bound then the total CPU
times will typically be less than your GPU times. You'll bee GPU
bound if you are using lots of fill/overloading the memory/overly
complex shaders.

It looks some compilers don't have a problem with OpenThreads not

Hi Sukender,
I don't feel this suggestion is appropriate for the OSG. Adaption of

The osgViewer:::CompositeViewer/Viewer architecture is designed to
support one frame loop driving all the windows associated with that
