Anyone knows if one of the OSG plugins for reading videos takes advantage of
the GPU to read it ? I've seen some documentation that Quicktime support
hardware decompression of H.264 videos, do you know if it's enabled by

Thanks !

Hi Andrey,
I did a proof of concept to put needed elements to osg. The main problem
is that currently there is no way to automatically get the location to
put the vertex attrib data.
The things i tried is to run the program once and dump the attrib
location and then edit the program to assign it.
HI Cedric,
I can't add to the discussion on skinning specifically but general
notes about bounding box and vertex attribute location as something I
can chip in with.
First up, the bounding box issue is something I'd be lazy and
conservative with - basically estimate the bounding box for the

ok, I think I have to reject my previous post and will have to say that BFS

The problem is, that whenever I do iterate over the child list and let accept()

I don't recall the details, but CompositeViewer and Viewer should
