ok so i have a 3D world, and i want the user to be able to point to an object on the screen (like a cube) and the computer to be able to realize that they are pointing at that object. what is the best way to do this? i assume lots of matrix multiplication with the mouse coordinates and the objects absolute position in 3D space?? thanks for any help
