Hi Werner, Could you back out a bit, and introduce the problem your are tackling at a high level so that others get a picture about what you are trying to achieve, diving into what solution you've code is often premature.
From what I can gather integration of the simulation code and rendering code is at the core of what you are trying to achieve. Could you explain more about the simulation code, such as how it's threaded, is synchronous to the rendering thread etc. Also on the rendering side, how do you want to render it? Robert.
