I'm assuming you've got one copy of the SG per node. In that case, you should do the sync() in Node::frameStart(). > Generally my implementation seems to be working, but in its current > state it is leaking those huge amounts of memory every frame, after > adding nodes to the graph and even more, when performing > transformations onto graph nodes. Is the application, the render clients or both leaking? You've got to figure out who is leaking the memory. The delta objects buffer quite some stuff (see [1]), so that might be one cause. However, they should not keep leaking memory over time. Have a try with valgrind on a small scene, let it run for some frames with modifications and see if you have hard losses, or if it's simply a matter of data pooling up somewhere. > The project is still running until the month July and I already spoke > to the other people involved, that once we have reached a final and > working state we might be willing to hand our source out, to serve as > an example application.

That's unfortunately correct, and this project would indeed be interesting. What SG are we talking about?
