Hello everybody!

I want to load and add new files during the rendering loop. The
ive-files are so big that the readNodeFile-function needs about 0.03
seconds to load the file and in worst case I have to load five of them.
I add the new nodes to a second scene graph that isn't rendered. Is
everything done, I switch the current rendered scene graph with the
second one but nevertheless the viewer stops for some milliseconds.

Now I would like to know if there is a way to flip between the to scene
graphs without any delay. Or maybe there is another way of adding new
big files during rendering without delay (or even without crashing the
application ;)?
I hope somebody can help me.

With kind regards,
