Is it possible to get the world coordinates in 2D given the screen coordinates( relative to the context beeing displayed )?
And vice-versa?
I need this to select objects in the screen using the mouse.
thx in advance, rgds,
Marcelo

Look at -
gluProject()
gluUnproject()
and also consult the Red Book chapter on Selection and Feedback. I think there’s some tutorials at NeHe too…
