Elimination the influence of the mesh geometry to the quality of global smoothing

In the last years computer performance has become very high, solution methods have been developed, so more and more numerical calculations can be done in an acceptable time. That is one reason why such methods are being used very frequently. However, not only the calculation itself, but also the visualisation of the data places a challenge on the techniques used. Simulation results have very special properties which have to be considered for the visualisation. Ignoring this fact produces an output that makes it impossible to produce confidence in the results. A high quality display of the results in real time is necessary, in order to sell the numerical simulation to a large audience. But the basic characteristics of the data must not be changed in order to keep the basic message. The techniques described here fulfil this very important requirement of scientific information visualisation
