Progressive meshes are an established tool for triangle mesh simplification. By suitably adapting the simplification process, progressive hulls can be generated which enclose the original mesh in gradually simpler, nested meshes. We couple progressive hulls with a selective refinement framework and use them in applications involving intersection queries on(More)
We present a simplification algorithm for triangular meshes, implemented on the GPU. The algorithm performs edge collapses on manifold triangular meshes driven by a quadric error metric. It uses data parallelism as provided by OpenCL and has no sequential segments in its main iterative structure in order to fully exploit the processing power of the GPU. Our(More)
The evolving developments of the recent decades in information management have resulted in a situation where information is stored and managed by a large variety of systems around the globe. The growing requirement for information support to the globalised social and economic forces makes efficient and effective availability of distributed information and(More)
Vector fields produced by experiments or simulations are usually extremely dense, which makes their manipulation and visualization cumbersome. Often, such fields can be simplified without much loss of information. A simplification method for 3D vector fields defined over tetrahedral meshes is presented. The underlying tetrahedral mesh is progressively(More)

Simulators are an inseparable part of the design and evaluation of distributed multi-agent protocols. In this work we put forward PViz, a novel visualisation tool built for one of the most prominent, publicly available P2P simula-tors, PeerSim. Our tool provides network visualisation for different overlays, interaction with the simulation through scenario(More)
