A Fast Geometric Multigrid Method for Curved Surfaces
Ruben Wiersma, Ahmad Nasikun, Elmar Eisemann +1
We introduce a geometric multigrid method for solving linear systems arising from variational problems on surfaces in geometry processing, Gravo MG. Our scheme uses point clouds as…
Evaluations of The Hierarchical Subspace Iteration Method
Ahmad Nasikun, Klaus Hildebrandt
This document contains additional experiments concerned with the evaluation of the Hierarchical Subspace Iteration Method, which is introduced in~\cite{Nasikun2021}}
The Hierarchical Subspace Iteration Method for Laplace--Beltrami Eigenproblems
Ahmad Nasikun, Klaus Hildebrandt
Sparse eigenproblems are important for various applications in computer graphics. The spectrum and eigenfunctions of the Laplace--Beltrami operator, for example, are fundamental fo…
DeltaConv: Anisotropic Operators for Geometric Deep Learning on Point Clouds
Ruben Wiersma, Ahmad Nasikun, Elmar Eisemann +1
Learning from 3D point-cloud data has rapidly gained momentum, motivated by the success of deep learning on images and the increased availability of 3D~data. In this paper, we aim…
Digitory, A Smart Way of Learning Islamic History in Digital Era
Dimas Agil Marenda, Ahmad Nasikun, Canggih Puspo Wibowo
In this paper, we would like to propose our web-based application for Islamic history learning system, named Digitory-Digital History. There are two main navigations to browse hist…
