However, there remain some difficulties to utilize such results in a design process due to the huge amount of data. Major problem is a handling of those data in comparing with other results, extracting useful information, archiving in a database and exchanging among the researchers. Firstly, the flow field is visualized using some display-based techniques such as a volume rendering method for a scalar field and LIC (Line Integral Convolution) or PEM (Pixel Exposure Method) for a vector field. And then, a vortical structure is interactively extracted from the flow field. In a two-dimensional case, some point-vortices are substituted for the distribution of the vorticity. Vortex sticks will be utilized in three-dimensions. Those vortex elements represent the flow fields. Since size of data is extremely reduced, it becomes easier to extract useful information from large-scale datasets. Also, vortex elements are utilized for the comparisons, the archives and the exchanges. This procedure is similar to a technique of data mining. It will be expected that this methodology becomes a basis of extracting design concepts from visualization information.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
