Conformal Surface Parameterization for Texture Mapping
In this paper, we give an explicit method for mapping any simply connected surface onto the sphere in a manner which preserves angles. This technique relies on certain conformal mappings from differential geometry. Our method provides a new way to automatically assign texture coordinates to complex undulating surfaces. We demonstrate a finite element method that can be used to apply our mapping...
متن کاملMesh Parameterization for Texture Mapping
In 3D graphical rendering, it is common to want to produce a rendered image of an object that’s as realistic as possible, subject to the limits of memory and computing power available. A commonly used technique that helps to achieve this realism is texture mapping. The parameterization, which is the subject of this project, defines how points in the texture relate to points on the object’s surf...

متن کاملGlobal Conformal Surface Parameterization
We solve the problem of computing global conformal parameterizations for surfaces with nontrivial topologies. The parameterization is global in the sense that it preserves the conformality everywhere except for a few points, and has no boundary of discontinuity. We analyze the structure of the space of all global conformal parameterizations of a given surface and find all possible solutions by ...
متن کاملConformal Slit Mapping and Its Applications to Brain Surface Parameterization
We propose a method that computes a conformal mapping from a multiply connected mesh to the so-called slit domain, which consists of a canonical rectangle or disk in which 3D curved landmarks on the original surfaces are mapped to concentric or parallel lines in the slit domain. In this paper, we studied its application to brain surface parameterization. After cutting along some landmark curve ...
