Hi:
Is there any way to draw an object only once?For example,if I load
a model via
osgDB::readNodeFile("****"),then I add the loaded model to rootNode of
scene.What
I want to do is that I want to draw the model once at the first
frame,during the other frames,I just keep the model drawn at the frist
frame(do not redraw the model ).
