Hello everyone, I'm experiencing performance problems with my osg scene. I have many (up to 100k) geometries to display a tree.
I'm building my whole scene graph at the beginning. To view it only partially I inserted root -> group -> PositionAttitudeTransform -> Switch -> (a/b) (a) LOD -> Geode -> Geometry or LOD -> BillBoard -> Geometry (b) Geode -> Geometry Now when the scene is only partially visible (using osg::Switch), it's laggy nonetheless. If I wanted to load and save my scene on demand, what would be the best possibility (in regards of performance) 1) write unneeded subgraphs to a file 2) cache unneeded subgraphs (how would I do this?) 3) use NodeMask on osg::Group (would this also black out the respective subgraph?) Looking forward for input. Thanks in advance.
