Vector and Flow Visualization
Fluid flow simulations play an important role in many scientific disciplines, for example, in the modeling of thermal hydraulics in a nuclear reactor, the blood flow in our heart chambers, and the ocean circulation in climate models. Effective visualization of 3D time-varying flow fields play a crucial role in understanding the complex dynamics of the flow data generated from those simulations. For the past two decades, researchers have developed various visualization techniques to enable effective analysis of large scale simulation output. Among the many directions of research, visualization of flow fields remains to be one of the most challenging problems in the field. As part of our endeavor in scientific visualization, Prof. Shen and his GRAVITY research group has developed many novels techniques in the past 2 decades to facilitate effective analysis and visualization of flow data. Our research focus includes:
-
✦Flow Feature Analysis and Exploration
-
✦2D and 3D Flow Line Seed Placement
-
✦Flow Texture Synthesis
-
✦Large Scale Particle Tracing
An example of our research can be found in this magazine article published in Computer Graphics Quarterly, an ACM SIGGRAPH publication.
