I understood how to cath mouse and keyboard events in the GLUI lib. But
I can't discover how to interact with the geodes in the SceneView (if
there is a way to do it).
How do you all make it in the lib you use?

Hi Fernando,
I know nothing about GLUI, but perhaps the osgmovie and osgcggui
examples will give you a bit of inspiration in the way that they use
an event callback to catch mouse and keyboard events.

Hi all,
I trying to create a GUI using the GLUI library.
To render my scene graph I used the sceneView class. But, is there
a way
to pick the geode using mouse using sceneView and GLUI? If yes,
how? If
no, what class I could use to do that?
Thanks,
Fernando

Hi,
you will have to "normalize" your mouse-coordinates to values in
[-1;1], then compute a "beam" that goes from the mouse-pointer into
the scene and then intersect this beam with the scene.
You will get a "hit-list", which is a vector of "hit", and a "hit"
(see ref-docs) contains information about geode, node and drawable
that was picked.
This is the overview, and the code I posted before contains all there
is to do already coded!
Regards,
Andreas
