3D Quasiconformal Representation and Solver

The analysis of mapping relationships and distortions in multidimensional data poses a significant challenge in contemporary research. While Beltrami coefficients offer a precise description of distortions in two-dimensional mappings, current tools lack this capability in the context of three-dimensional space. This paper presents a novel approach: a 3D quasiconformal representation that captures the local dilation of 3D mappings, along with an algorithm that establishes a connection between this representation and the corresponding mapping. Experimental results showcase the algorithm's effectiveness in eliminating foldings in 3D mappings, as well as in mapping reconstruction and generation. These features bear a resemblance to the 2D Linear Beltrami Solver technique. The work presented in this paper offers a promising solution for the precise analysis and adjustment of distortions in 3D data and mappings.
