Is there a way to find the relationship between screen coordinates and world coordinates without doing complex time-consuming trig? And if “selection” isn’t this, what is it?
Simply, you click and you select an object.
I mean how do you do it in code…
Heh, do you have anything a little more idiot-friendly? There are topics in there that I don’t think I’ve learned about yet. Should I just forget about it then?
Try http://nehe.gamedev.net - they have a picking tutorial… not sure of the tut number. Also, http://www.gametutorials.com/Tutorials/opengl/OpenGL_Pg3.htm under Object Selection

If you just want to transform screen coordinates to world coordinates and vise versa, you should look into gluProject and gluUnproject.
