Hello ML, I am working on a QSGGeometryNode, which geo needs to get updated every frame ( visualization of data ). At the moment I am changing the vertices via the QSGNode::update-method and mark it as QSGNode::DirtyGeometry. I have several 100 vertices which are unchanged, only a couple of vertices will get changed.
Is this ther most perfromant way to do this? I am not sure if the scenegraph needs to update the whole batching each frame? Special on an embedded device I can observe that my performance is pretty bad ( 16 FPS ). Which is the recommended way to do this? Anny recommendations? Thanks a lot, Kim Kulling
