Higher Order Barycentric Coordinates [PDF]
Computer Graphics Forum, 2008 AbstractIn recent years, a wide range of generalized barycentric coordinates has been suggested. However, all of them lack control over derivatives. We show how the notion of barycentric coordinates can be extended to specify derivatives at control points. This is also known as Hermite interpolation. We introduce a method to modify existing barycentric

Interior Distance Using Barycentric Coordinates [PDF]
Computer Graphics Forum, 2009 AbstractThis paper introduces a framework for defining a shape‐aware distance measure between any two points in the interior of a surface mesh. Our framework is based on embedding the surface mesh into a high‐dimensional space in a way that best preserves boundary distances between vertices of the mesh, performing a mapping of the mesh volume into this

Circles in barycentric coordinates [PDF]
Mathematical Communications, 2004 Let ABC be a fundamental triangle with the area ∆. For a circle K the powers of vertices A,B,C with regard to K divided by 2∆ are said to be the barycentric coordinates of K with respect to triangle ABC. This paper gives some theory and applications of these coordinates.

Computer-Aided Assessment of Displacement and Reduction of Distal Radius Fractures
Diagnostics, 2021 This study aims to investigate displacements and reductions of distal radius fractures using measurement indices based on the computer-aided three-dimensional (3D) radius shape model. Fifty-two distal radius fracture patients who underwent osteosynthesis

On the convergence the barycentric method in solving diffraction problems on conductive thin screens
Физика волновых процессов и радиотехнические системы, 2020 Annotation In this article, the use of the barycentric method is proposed for the numerical solution of problems of diffraction of electromagnetic waves on infinitely thin perfectly conducting screens of arbitrary shape. The numerical solution is formed

A Generalization of the Klamkin Inequality [PDF]
, 2009 A generalization of a geometric inequality of Klamkin is established by considering the triples of barycentric coordinates of the points from a set which is included in the plane of the fundamental triangle.

On Some Multivariate Distribution of Random Walks [PDF]
The Egyptian Statistical Journal, 1974 In this note we consider a probability scheme which can be interpreted a random walk with jumps which form a Poisson process. The scheme is tackled by solving some difference differential equation which appear in queueing theory.

On Spherical Barycentric Coordinates
SSRN Electronic Journal, 2022 This paper describes a novel construction of generalized barycentric coordinates of points on a sphere with respect to the vertices of a given spherical polygon that is contained in a common hemisphere. While in the standard approach such coordinates are derived from their classical planar counterparts (e.g.
