An Axis-Aligned Bounding Box

A frustum defined by the 6 containing planes Planes are ordered left, right, top, bottom, near, far Normals point into the contained volume

A plane defined by a unit normal and distance from the origin along the normal Any point p is in the plane if n.p + d = 0 For planes defining half-spaces such as for frusta, if n.p + d > 0 then p is on the positive side (inside) of the plane.
