Hi all, Bit of a novice question here I''m afraid. I have a strip of bitmaps rendered to the screen (thumbnail style) in OpenGL. I need to allow the user to select these by mouse clicking. How do I do this? please if you could direct me to a tut or give help it would be greatly appreciated. I have tried Jeff''s selection technique on Nehe but that is for primitive and does not work on BMP''s. Thanks guys Paul
