Fast 3D Analytical Affine Transformation for Polygon-Based Computer-Generated Holograms

open access: yesApplied Sciences, 2022
We present a fast 3D analytical affine transformation (F3DAAT) method to obtain polygon-based computer-generated holograms (CGHs). CGHs consisting of tens of thousands of triangles from 3D objects are obtained by this method.
