Dynamic Adaptive Meshes and Stellar Theory
نویسنده
چکیده
In this paper we present dynamic adaptive meshes, a scheme for maintaining a conforming triangulation of time-varying surfaces. The user supplies an initial mesh, a surface sampling procedure and a set of adaptation criteria. The mesh is automatically modified in order to conform to user defined characteristics, while the surface changes over time. Our scheme is very simple to implement. It employs a half-edge data structure without any extra storage requirements. The mesh has an underlying semi-regular multiresolution structure. Furthermore, the specification of desired mesh characteristics can be based on very general adaptation rules.

Adaptive meshes and shells: irregular triangulation, discontinuities, and hierarchical subdivision
Adaptive meshes are dynamic networks of nodal masses interconnected by adjustable springs. They are useful for nonuniformly sampling and reconstructing visual data. This paper extends the adaptive mesh model in the following ways: it (i) develops open adaptive meshes and closed adaptive shells based on triangular and rectangular elements, (ii) proposes a discontinuity detection and preservation...
متن کاملSketch-based modeling and adaptive meshes
We present two sketch-based modeling systems built using adaptive meshes and editing operators. The first one has the capability to control local and global changes to the model; the second one follows geological domain constraints. To build a system that provides the user with control of local modifications we developed a mathematical theory of vertex label and atlas structure for adaptive mes...
متن کاملA two dimensional Simulation of crack propagation using Adaptive Finite Element Analysis
Finite element method (FEM) is one of the most famous methods which has many applications in varies studies such as the study of crack propagation in engineering structures. However, unless extremely fine meshes are employed, problem arises in accurately modelling the singular stress field in the singular element area around the crack tip. In the present study, the crack growth simulation has b...

متن کاملAnimation Model Simplifications
In this paper, we propose a new framework for the representation of deforming meshes by only updating necessary changes of the connectivity. The deforming meshes, which is also known as time-varying surfaces, are often constructed with static connectivity. To progressively represent the deforming meshes with level-of-details, people can simplify the meshes independently to obtain good simplific...
