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 ...
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 ...
Objective Finite-Time Saddles and their Connection to FTLE
(The Eurographics Association, 2019)
Based on an intuitive physical definition of what a finite-time saddle-like behavior is, we derive a mathematical definition. We show that this definition builds the link between two FTLE-based saddle generalizations, which ...
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, ...
