Abstract
In order to grasp the inner structure of three dimensional data efficiently, various volume visualization techniques have been widely used. However, appropriate parameter values for such visualization techniques are difficult to be chosen without taking into account the features of volume data. We have developed a method for setting parameter values by analyzing the topological transitions of the isosurfaces within the volumetric domain. In this paper, we newly apply the topological framework to a fluid dataset, and adaptively choose target values for extracting iso-pressure surfaces embeded in the dataset.
