Hi J-S, Now I see what you mean by world coordinates and your calculations! Stupid newbie me! =) I usually have a hard time relating OSG and OpenGL (which I'm no expert btw), but in the end the concepts are all the same!!!
I just have a small little question: when you multiply your screen coordinates by the inverse matrix you are using the z values of 0.0 and 1.0 for the points on the near and far planes, right? Are you using these values because they were previously set on your projection matrix or for some other reason? All in all, I think my problem will be solved now! Thank you so very much again! I appreciate all your help and good will!
