Thx once again Carsten, would not have been that far without your help :)

not that important, just if there would have been an alternative i'd have
used it, just for some statistics.

for more details
for the moment i skipped shadows, we have to think about how to re-implement
it in our framework at another time.
One question once again, then i'm already done with converting it (then
testing and looking if everything works) starts
i'm struggling about how i can reimplement the following, or if that isn't
necessary any more?
GeometryPtr geo = Geometry::create();
...
geo->getIndexMapping().push_back(Geometry::MapPosition);
geo->getIndexMapping().push_back(Geometry::MapColor |
Geometry::MapNormal |
Geometry::MapTexCoords);
cheers, Georg
