When you guys do mirrors, you create a clipping plane so that the mirrored objects don't come out of the mirror, right? When you create a clipping plane, is it relative to the camera, or is it in world space? I would assume that it's relative to the camera, but I thought I'd ask anyway .
See, I've been getting the hang of planes and normals, so much that I'm finding it easy to project points onto planes and mirroring things. Next I'm going to make a function that determines the distance from a point to a line...I'm making a terrain editor so I need a way to select points that are a certain distance away.
