Exact hidden-surface removal in digitally synthetic full-parallax holograms
, 2005 A new algorithm for removing hidden surfaces from reconstruction of computer-generated holograms is presented. The object used in the algorithm is defined by surface model and each polygon composing the object provides a mask for blocking the incident ...
