[osg-users] Projecting a point given a camera

[Michele Bosi]

Hello,
I need to project the mouse coordinates in world coordinates given a
Camera*, how can I implement this? I expected some "project"/"unproject"
method similar to gluProject/Unproject in the Camera class or in the Viewer
or in Matrix but couldn't find anything. Can anyone point me in the right
direction before I start cut-and-pasting the sourcecode from MESA's
gluProject()? :)

Thanks,
Michele
