Ring-based hierarchical networks are interesting alternatives to popular direct networks such as 2D meshes or tori. They allow for simple router designs, wider communications paths, and faster networks than their direct network counterparts. However, they have a constant bisection bandwidth, regardless of system size. In this paper, we present the results of a simulation study to determine how ...

Lighting algorithms for outdoor scenes suffer from the sheer geometric and lighting complexity of such environments. In this paper we introduce an efficient, hierarchical solution to the problem of outdoor illumination. Data structures and sampling algorithms are presented, permitting the integration of complex and natural objects in a hierarchical radiosity simulation system. This new approach...

A local multilevel product algorithm and its additive version are analyzed for linear systems arising from the application of adaptive finite element methods to second order elliptic boundary value problems. The abstract Schwarz theory is applied to verify uniform convergence of local multilevel methods featuring Jacobi and Gauss-Seidel smoothing only on local nodes. By this abstract theory, co...

We describe a hierarchical volumetric representation of input meshes yielding isocontour output progressively and with decreasing geometric error. The maximum tolerable error bound can be prespeci ed, or incrementally reduced receiving the extra detail in the isosurface with minimal redundancy. We use a hierarchical tetrahedral representation generated via recursive edge-bisections and approxim...

Convolutional neural networks (CNNs) have made great breakthroughs in 2D computer vision. However, their irregular structure makes it hard to harness the potential of CNNs directly on meshes. A subdivision surface provides a hierarchical multi-resolution structure, which each face closed 2-manifold triangle mesh is exactly adjacent three faces. Motivated by these two observations, this paper pr...

Abstract The finite element method is classically based on nodal Lagrange basis functions defined conforming meshes. In this context, total reaction forces are commonly computed from the so-called “nodal forces”, yielding higher accuracy and convergence rates than reactions obtained differentiated primal solution (“direct” method). cell isogeometric analysis promise to improve interoperability ...

At present, we design a framework for streaming of 3D static model with rate adaptation techniques called TCP-Friendly Rate Adaptation. The 3D model in our framework is compressed with progressive meshes method [Hoppe96]. Exploited the dependency from progressive meshes, we transmit 3D model progressively.
