how to do clipping?
hi all, I have one qusetion abt building a game world. Suppose the world is of size 1000 unit x 1000 unit and I want to limit the visiion of the player to 100 unit by gluPerspective. However, once i say the clipping plane in this way, there is a grey plane 100 unit away the player, I know that it is the clipping plane. But since I have a skybox of blue, it is indeed ugly for having such a grey plane. I would like to ask is there any way to eliminate that grey while can limit the player vision? Thanks a lot
