Fast 3D Analytical Affine Transformation for Polygon-Based Computer-Generated Holograms [PDF]
Applied 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.

Quantization for infinite affine transformations [PDF]
Fractal and Fractional, 2016 Quantization for a probability distribution refers to the idea of estimating a given probability by a discrete probability supported by a finite set. In this article, we consider a probability distribution generated by an infinite system of affine transformations {Sij} on R2 with associated probabilities {pij} such that pij>0 for all i,j∈N and ∑i,j ...
