On the Constrained Solution of RBF Surface Approximation

open access: yesMathematics, 2022
In this contribution, a scattered data approximation problem, chosen from the literature and using the Radial Basis Function (RBF) approach, is considered for the application of point cloud modelling.

Effective interpolation of scattered data on a sphere through a Shepard-like method

open access: yesMathematical Modeling and Computing, 2023
The current paper introduced two approximation operators of large scattered datasets for spherical interpolation. The suggested solution method is an extension of Shepard's well-known method of spherical interpolating, which uses the inverted distances ...

Cubic Bézier-Like Triangular Patches for Rainfall Scattered Data Interpolation and Visualization [PDF]

open access: yesITM Web of Conferences
Scattered data interpolation plays an important role in computer graphics and scientific visualization. This method can be used to interpolate any regular or irregular data sets. For instance, rainfall distribution is an example of an irregular data that

The 1-D Hermite Shepard and MLS method [PDF]

open access: yesMathematics and Computational Sciences, 2021
In many applications, one encounters the problem of approximating 1-D curve and 2-D surfaces from data given on a set of scattered points. Meshless methods strategy is based on some facts: (1) deleting mesh generation and re-meshing, (2) raising smooth ...

Scattered Data Interpolation: Tests of Some Method [PDF]

open access: yesMathematics of Computation, 1982
This paper is concerned with the evaluation of methods for scattered data interpolation and some of the results of the tests when applied to a number of methods. The process involves evaluation of the methods in terms of timing, storage, accuracy, visual pleasantness of the surface, and ease of implementation.

Convergence and error estimates for pseudo-polyharmonic div-curl and elastic interpolation on a bounded domain

open access: yesJournal of Numerical Analysis and Approximation Theory, 2023
This paper establishes convergence rates and error estimates for the pseudo-polyharmonic div-curl and elastic interpolation. This type of interpolation is based on a combination of the divergence and the curl of a multivariate vector field and ...
