void org.hfbk.vis.VisClient.reset ( )

reset the client to its clear state. the just started VisClient usually adds some welcome visuals that are not reconstructed here.

void org.hfbk.vis.VisClient.init ( )

does initalisation.

some startup visuals are added. reset() is called, which adds visuals too. however, reset() is called also by user reset request so it should provide some empty space.

Here is the caller graph for this function:

void org.hfbk.vis.VisClient.paintGL	(	int	w,
		int	h
	)

main rendering and event processing.

this works as follows: -we measure the time since last frame to update movements -we init the 3d viewport -we apply the camera (maybe an animated one) -we render and event process the root node VisRoot, which recursively renders the whole tree -we render and event process the heads up display -we filter events (see below) -we process viewpoint events

AWT input events are never consumed by VisNodes as in one frame processing the correct target cannot be determinated (visuals maybe overlapping!). they are folowed up by VisEvents when the correct target is determined. after all we clean up all AWT events and let the VisEvents enter the next frame to get processed.
