These elements are specific to logical camera sensors. A logical camera reports objects that fall within a frustum. Computation should be performed on the CPU. Near clipping distance of the view frustum Far clipping distance of the view frustum Aspect ratio of the near and far planes. This is the width divided by the height of the near or far planes. Horizontal field of view of the frustum, in radians. This is the angle between the frustum's vertex and the edges of the near or far plane.
