View Selection of Comparative for Mode Water Regions in a VR Space

Mode water is seawater mass that has similar physical characteristics. The physical characteristics are caused by the condition change of air on the seawater surfaces, and therefore mode water plays an important role in analyzing the climate change. Mode water has been defined with various parameters and different thresholds. They may cause different shapes of mode water even the same mode water is to be observed. Therefore, we are developing a visualization tool which extracts various shapes of mode water with various conditions from observation and simulation datasets respectively. This paper proposes a user interface for observation and comparison of mode water shapes in a VR space and a view selection technique for observation of similar/dissimilar parts of the mode water shape pairs. This paper introduces examples of mode water shape pairs which have small or large dissimilarity. By selecting a viewpoint, we walk through in a VR space to observe a target part with the intuitive simple operation. Moreover, we can observe the target part in detail and understand the characteristics of shape pairs efficiently. 芸術科学会論文誌 Vol.17,No.4,pp.105-114 (2018)
