Fast computation method of high-definition computer-generated holograms with localized polygon calculation and viewing zone segmentation

Abstract

High-definition (HD) computer-generated hologram (CGH) has been actively researched because it can display realistic and high quality display [1-2]. But HD CGH re-quires a lot of computational time and great memory be-cause it has a large scale and a lot of computation. There-fore, fast calculation method is an important key element of HD CGH. In this paper, we introduce the viewing zone segmentation and the local polygon calculation method. And we check the calculation efficiency enhancement by applying them simultaneously.
