ok, great.

AFAIK there is only support for polygonal data in the library at this
point. One "quick and dirty" option could be to render your volume data
with VTK itself and render the OpenSG scene afterwards on top (or the
other way around). You would use a PassiveBackground to avoid clearing
the color/depth buffers when doing the OpenSG rendering as the second step.
Cheers,
Carsten
