VAPORÕs Interaction Techniques for
Understanding Massive Turbulence Datasets
¥Interactive feedback is key to visual data understanding
1.Multiresolution data browsing
–Enables interactive access to terabyte datasets
2.Visual color and opacity editing with histograms
–Identify features of interest by color and opacity
3.Export/import data to/from analysis toolkit
–Currently supporting IDL¨
4.Use planar probe for visual flow seed placement
–Local data values guide seed placement
5.Track structure evolution with field line advection
–Time-evolution of structures shown by field line motion
6.Use the GPU for interactive rendering
–Cartesian, Spherical, Terrain-following (WRF) grids
