1. A system comprising: a real-time view-frustum (RTVF) culling processor adapted to: receive tag-associated data for each of one or more wireless tags; receive camera information for a film segment generated by a camera; process the received camera information to determine, for the film segment, a view frustum of the camera; and correlate the tag-associated data with the view frustum for the film segment to generate frustum-culling information identifying one or more of the wireless tags as intra-frustum tags within the view frustum.
