本文提出了一种新的计算大规模计算全息图的方法。该方法利用位移菲涅耳方法对波场进行区域分割和传播。结果，即使在整个帧缓冲器不能存储在主存储器中的情况下，也可以计算大的CGH。所产生的全视差CGH具有40亿像素的大小，并重建具有强烈深度感的光滑表面物体的精细图像。
A novel technique is presented for calculating large-scale CGHs by using polygon-based method. In the technique, wave fields are regionally segmented and propagated by using the shifted Fresnel method. As a result, large CGHs can be calculated even in the case that the whole frame buffer can not be stored in main memory. The produced full-parallax CGH has the size of four billion pixels and reconstructs the fine image of a smooth surface object accompanied with a strong depth sensation.
