[osg-users] Implementing a 3D GUI

[Brian]

Unfortunately, this will most likely not be open sourced due to the fact that I'm developing it for my employer.  There is certainly an advantage to open sourcing it, I know, especially when it comes to fixing bugs and adding new features.  However, my employer probably isn't ready to take that step forward yet.

Incidentally, I was able to get the picker to work with my application.  It took a little extra doing since the other 3rd party utility that I use, Delta3D, doesn't use the osgProducer class (still using OSG 1.2).  My only bugs now that I have seen involve the mouse cursor flickering or the caret not showing (depending on the implementation used which gets complicated.)  Unfortunately, those aren't OSG related; so asking for help with those is more than a bit off topic.

My problem is how to determine what the coordinates of my mouse cursor are (in 2D space) when the mouse is over the drawable.  Preferably, I'd like to know the 2D coordinate of the mouse position in terms of (0..1, 0..1).  The drawable itself is in 3D space.

I've taken a look at the osgPick example and see that I can get the local and world coordinates of an intersection, but I am unclear as to whether there are any helper OSG classes/functions that will allow me to map that intersection point to the correct 2D coordinate to pass to the Flash player.  Also, is it possible to restrict the intersection tests  for my Flash drawables only?
