[osg-users] problem with picking/intersecting in window space

[Andreas Mueller]

I found the cause of my problem:
I overlooked that I'm using a second camera (with it's own computed znear/zfar values) in my scene graph. Though the intersector is working with the main camera (and it's znear / zfar values, that are different from those if the second camera).
To work around this problem, I do the intersection in world coordinates with the world eye coordinate as starting point.

Cheers,
Andreas
