Hi Carsten, Ok thank you just wanted to know if I was reinventing the wheel...
Other topic: I am still on the way of trying to use OpenSG in a multithreaded environment. >From my understanding, the classes use a so called thread aspect. Does that have something to do with any of the native thread ids or how would I match them against each other to tell both open sg and the other apps parts which thread they are on? I am having several models that have to be calculating some simulation in the background and manipulate open sg nodes and cores etc in one aspect, a background threads aspect. In the mean time the gui thread might be trying to draw the scene in another aspect as I understand it. The aspects btw are numbered as 1 and 2, right?! Every time I am switching the aspects something is crashing around a beginEditCP or endEditCP. What might I be doing wrong? Any Clue?

We do not have a foreground that does something along the lines you describe above. Since you want your hud objects to be 3d themselves it may be simpler to just use a second viewport of the same size (with a passive or depth clear background) but different scene as has been suggested in the other recent thread on fore/backgrounds.
