So we are writing a HUD.
Is there any way (besides an OpenGL callback in the Draw Process) to
ensure that a subtree is drawn last and that Z-buffering is disabled?
Right now I am using a Post Draw Callback off the Scene Node, to render
a subtree that is NOT part of the Scene Graph.
The bummer is that the HUD is more of a User interface than a fighter
cockpit HUD and so it is movable and adjustable. Thus there is a
slightly complex subtree that needs to be rendered. (It is not just a
list of GeoSets that I need to call ->draw() on)
Is there a way to hand a subtree to the draw traversal and have it do it
for me, or will I have to write a traverser of my own?
