I think the second error should probably be taken at face value. > Is gluUnProject the correct method for this purpose (i.e. window > coordinates --> object coordinates) ? Yes, that is the correct method. I think you might have to keep local copies of your modelview and projection matrices as you modify them and use the local copies in the calculations (a pain, I know). -- Jon --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
