Hi, I am using osg 2.0 on Windows XP.
I am trying to get my own subclass of TerrainTechnique (which is heavily inspired by GeometryTechnique) to work. Similar to GeometryTechnique, I set and populate the vertex arrays and primitive sets of an osg::Geometry object. Differently from GeometryTechnique, in the cull() method I incrementally update the vertex arrays; remove all primitive sets from Geometry and set and populate new ones. (i.e. a dynamic terrain) Here is my question: Do I need to do any specific things to use vbo's? I only call setUseVertexBufferObjects(true) on Geometry and get incorrect results, as if the primitives are not updated. No problems when not using vbo's. Before getting into debugging, I wanted to know if I am missing anything simple (maybe setting a flag, or flushing a buffer?).
