frustum
A volume of space that includes everything that is currently visible from a given camera viewpoint. A frustum is defined by six planes arranged in the shape of a pyramid with the top chopped off. If a point is inside this volume then it is in the frustum and it is potentially visible (if not obscured by another object). If a point is outside of this volume then it is outside the frustum.
