Description: A frustum is formed of 6 planes representing the near, far, left, right, top, and bottom of a 3D box. It is usually used with cameras to represent the veiwable area of the camera and can be tested against various types of primites (cylinders, spheres, AABB's, etc.) to determine objects that are partially or entirely inside the box. This helps determine which objects should be drawn.
