In this paper, we propose a new efficient topology estimation algorithm to construct a multiresolution polygonal mesh from measured three-dimensional (3-D) range data. The topology estimation problem is defined under the constraints of cognition, compactness, and regularity, and the algorithm is designed to be applied to either a cloud of points or a dense mesh. The proposed algorithm initially...

This paper presents a generic approach to mesh global optimization via node movement, based on a discrete graph-theoretic model. Mesh is considered as an electric system with lumped parameters, governed by the Kirchhoff’s voltage and circuit laws. Each mesh element is treated as a multi-pole electric component, relating input electric potentials to the output via a transfer function. We automat...

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 emp...

Live 3D reconstruction of a human as a 3D mesh with commodity electronics is becoming a reality. Immersive applications (i.e. cloud gaming, tele-presence) benefit from effective transmission of such content over a bandwidth limited link. In this paper we outline different approaches for compressing live reconstructed mesh geometry based on distributing mesh reconstruction functions between send...

As there is a growing need for the cost effective and highly dynamic large-bandwidth networks over large coverage area , the Wireless Mesh Network provide first step towards effective communication. A Wireless Mesh Network is one of the most advanced wireless network used for communication. During their operating period , the wireless mesh network may suffer from frequent link failure which res...

Particle tracking methods are a versatile computational technique central to the simulation of a wide range of scientiic applications. In this paper we present a new parallel approach for the dynamic partitioning of particle-mesh computational systems. The approach uses a framework, the \in-element" particle tracking method, based on the assumption that particle trajectories are computed by pro...
