In this paper we present a parallel algorithm, implemented using MPICH, for isosurface extraction from volumetric data sets. The main contribution of this paper is in the analysis and performance improvements of the different phases of the isosurface production process including computation and output generation. The resulting algorithm is...

In a distributed visualization environment transmission time is dominant because of the amount of data to be moved and the limitations of available bandwidth. In this paper we address the problem to speed up the compression operation of large Triangulated Irregular Networks (TIN) using commodity clusters. In our case TINs represent isosurfaces...

We present a practical approach to the design of a Web system for 3D and volumetric data interrogation and visualization. This Web application provides different functionalities including isosurface extraction, mesh simplification, output file production in a standard format, and data compression. The application is designed in a modular way,...

Remote visualization is a key issue in many Grid applications and a demanding task both from the design and the computational point of view. For these reasons adequate algorithms and programming tools are necessary in order to face problems that arise implementing a remote visualization system for Grid architectures. In this paper we report our...

Scientists but also industrial researchers nowadays have unprecedented computing and instrumental capability for studying and simulating natural phenomena at greater accuracy, and this leads to the production of huge amount of data. To store and share these data collections is now emerging the use of the Grid as a very large data repository....
