Hello all, I am displaying the nodes under mouse on a HUD (based on the Pick Example).
I am trying to turn this display on/off based on if user presses some key. However, I am having trouble implementing this. In my main GUI thread, user presses the key and I try to turn off the display (by setting a variable and cleaning up the text). But in the background the pick procedure is still running and it is sometimes causing thread sync problems for the variable and the Text box. I am looking for more elegant way of doing this. My Display HUD is directly under the root (just as in the example). Is there a way I can turn off its visibility or make it "non-renderable"? One way is I can remove and add the display HUD every time the key is pressed. But in that case we need to make our Root as Dynamic. I am not sure if that would be good approach. Is there no simple way, something like HUD->SetRenderable(false) ?? Or can I somehow make it "culled" ?? Any good solution is appreciated. Thank you. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
