SmoothViz: Visualization of Smoothed Particle Hydrodynamics Simulation Data

People: Jun.-Prof. Dr. Paul Rosenthal, Dr. Vladimir Molchanov, Prof. Dr.-Ing. Lars Linsen

Collaborators: Prof. Dr. Stephan Rosswog

Description: Smoothed Particle Hydrodynamics (SPH) simulations are widely been used in the field of astrophysics due to their natural adaptivity and robustness. Particle can move freely within a 3D space and reside where high accuracy is required. To account for the adaptivity during visualization, visualization methods are developed that take as input a large set of particles with scalar or vector-valued data values assigned to them and directly display the represented features. Scalar fields are visualized using surface extractions based on isocontouring or level set computations. Point-based surface rendering mechanisms are developed to display the extracted surfaces. Time coherency needs to be exploited to efficiently deal with time-varying data. Vector fields are visualized using geometric flow visualization approaches. All approaches will be integrated into an operating system for visual exploration of SPH data.
