Recall that when ax + by + cz + d = 0, that is when you are on the plane. So the amount you are off by is proportional to the normal vector's magnitude. This signed distance equation actually only holds true if (a, b, c) is a normal vector.

But I guess it doesn't matter since we're just trying to find the max anyways.
