The ever growing size of data sets resulting from industrial and scientific simulations and measurements have created an enormous need for analysis tools allowing interactive visualization. A promising hierarchical approach in the area of numerical simulation is called sparse grids. We present two major visualization algorithms working directly on the sparse grid representation of the data set. One of them is interactive particle tracing, which continues to be an important utility for evaluating CFD simulations. The other one is volume ray casting, which is of interest in many areas dealing with three-dimensional scalar data. Additionally we have been able to employ texture hardware support for the necessary function interpolation. Hence, we are able to perform volume visualization methods on compressed data sets at interactive frame rates, which is not possible with other methods like wavelets or fractal compression. In particular, we are able to handle sparse grids of level 13, which correspond to regular volumes of 8193^3 voxels.

Modern web-based Scientific visualization applications try to overcome common limitations imposed by limited internet bandwidth, server bottlenecks or network latency. A further aspect is the desire to gain platform independence by solely using instruments which are platform independent by conception: the programming language Java, the Virtual Reality Modeling Language (VRML), or the 3D API *** present a prototype of a hybrid web-based Scientific visualization system which makes use of the increasing computational power of modern desktop workstations and personal computers on the client side, and the superior performance provided by a powerful machine on the server side. In order to achieve high interaction rates and to balance computational load the user can dynamically assign selected tasks to his client or to the *** the scientific field of human modeling we have implemented a hybrid web-based toolkit for the modeling of human muscles and skin. Our application allows the on-line generation and manipulation of three-dimensional implicit muscle models in a heterogeneous network and it offers various parameters to adjust computation and response time versus rendering quality.
