Hi, ok no answers for a while so I guess i need to explain my problem a bit more. The task is to render a selected set of lines out of a bigger dataset (http://sites.google.com/site/schurade/pic14.png). The test data I'm usually working with is about 70k lines with approx. 5M points but can get bigger easily. The selection is interactive so the rendering needs to be fast so it doesn't get too sluggish. My previous implementation used VBO's or vertex arrays and worked really good even on the slow machine of my boss ( dual core, gforce8, 2 gig ram), so this is what he expects now from the new app which uses OSG.
The data (vertex array and at least one color array) is stored in stl::vector<float> which allos pointer access. I'd prefer to render directly from these arrays and not have to copy it into any osg structures for time and memory consumption reasons. My approach was the above mentioned draw implementation but I can't get it to work. Thank you!
