A review of algebraic multigrid
, 2001
"... Since the early 1990s, there has been a strongly increasing demand for more efficient methods to solve large sparse, unstructured linear systems of equations. For practically relevant problem sizes, classical one-level methods had already reached their limits and new hierarchical algorithms had to b ..."

discretized on unstructured meshes, both in 2D and 3D. Since AMG does not make use of any geometric information, it is a “plug-in ” solver which can even be applied to problems without any geometric background, provided that the
A new meshless local Petrov-Galerkin (MLPG) approach in computational mechanics
- Comput. Mech
, 1998
"... Abstract: A comparison study of the efficiency and ac-curacy of a variety of meshless trial and test functions is presented in this paper, based on the general concept of the meshless local Petrov-Galerkin (MLPG) method. 5 types of trial functions, and 6 types of test functions are explored. Differe ..."

. Different test functions result in different MLPG methods, and six such MLPG methods are pre-sented in this paper. In all these six MLPG methods, absolutely no meshes are needed either for the interpo-lation of the trial and test functions, or for the integration of the weak-form; while other meshless
An Eulerian Numerical Method for Geometric Optics
"... . The classical description for geometric optics is Lagrangian. It is possible to switch to an Eulerian representation but, in presence of caustics, the full Lagrangian solution cannot be computed using a Eulerian method. We present the mathematical background of the problem and several numerical to ..."

An Eulerian description of fluids containing visco-elastic particles
"... Abstract. Equations governing the flow of fluid containing visco-hyperelastic particles are developed in an Eulerian framework. The novel feature introduced here is to write an evolution equation for the strain. It is envisioned that this will simplify numerical codes which typically compute the str ..."

Tour into the picture: Using a spidery mesh interface to make animation from a single image
, 1997
"... A new method called TIP (Tour Into the Picture) is presented for easily making animations from one 2D picture or photograph of a scene. In TIP, animation is created from the viewpoint of a camera which can be three-dimensionally "walked or flownthrough" the 2D picture or photograph ..."

or photograph. To make such animation, conventional computer vision techniques cannot be applied in the 3D modeling process for the scene, using only a single 2D image. Instead a spidery mesh is employed in our method to obtain a simple scene model from the 2D image of the scene using a graphical user interface

Mesh parameterization methods and their applications
- FOUNDATIONS AND TRENDSÂŐ IN COMPUTER GRAPHICS AND VISION
, 2006
"... We present a survey of recent methods for creating piecewise linear mappings between triangulations in 3D and simpler domains such as planar regions, simplicial complexes, and spheres. We also discuss emerging tools such as global parameterization, inter-surface mapping, and parameterization with co ..."

We then briefly review the pertinent mathematical background and terminology, before proceeding to survey the existing parameterization techniques. Our survey summarizes the main
