TACHYON: Efficient Shared Memory Parallel Computation of Extremum Graphs
Abhijath Ande, Varshini Subhash, Vijay Natarajan
The extremum graph is a succinct representation of the Morse decomposition of a scalar field. It has increasingly become a useful data structure that supports topological feature d…
Jacobi Set Driven Search for Flexible Fiber Surface Extraction
Mohit Sharma, Vijay Natarajan
Isosurfaces are an important tool for analysis and visualization of univariate scalar fields. Earlier works have demonstrated the presence of interesting isosurfaces at isovalues c…
Comparative Analysis of Merge Trees using Local Tree Edit Distance
Raghavendra Sridharamurthy, Vijay Natarajan
Comparative analysis of scalar fields is an important problem with various applications including feature-directed visualization and feature tracking in time-varying data. Comparin…
A GPU Parallel Algorithm for Computing Morse-Smale Complexes
Varshini Subhash, Karran Pandey, Vijay Natarajan
The Morse-Smale complex is a well studied topological structure that represents the gradient flow behavior between critical points of a scalar function. It supports multi-scale top…
