Illustrative Rendering of Vortex Cores
(The Eurographics Association, 2013)
Vortices are features crucial for understanding transitional and turbulent flow fields, and have often been visualized using isosurfaces, hulls, and line-like structures. However, they have not been represented in a ...
Error Estimates for Lagrangian Flow Field Representations
(The Eurographics Association, 2016)
Computing power outpaces I/O bandwidth in modern high performance computers, which leads to temporal sparsity in flow simulation data. Experiments show that Lagrangian flow representations (where pathlines are retrieved ...
WebGL-Enabled Remote Visualization of Smoothed Particle Hydrodynamics Simulations
(The Eurographics Association, 2015)
Large-scale simulations are often performed on machines without the necessary graphics hardware for visualization. Transferring full resolution data to a suitable machine for visualization is impractical and undesirable. ...
Analysis of Error in Interpolation-Based Pathline Tracing
(The Eurographics Association, 2016)
Chandler et al. [COJ15] presented interpolation-based pathline tracing as an alternative to numerical integration for advecting tracers in particle-based flow fields and showed that their method has lower error than a ...
Local Data Models for Probabilistic Transfer Function Design
(The Eurographics Association, 2013)
A central component of expressive volume rendering is the identification of tissue or material types and their respective boundaries. To perform appropriate data classification, transfer functions can be defined in ...
Clustering Moment Invariants to Identify Similarity within 2D Flow Fields
(The Eurographics Association, 2015)
Moment invariants have proven to be a useful tool for the detection of patterns in scalar and vector fields. By their means, an interesting feature can be detected in a data set independent of its exact orientation, position, ...
