GS-Surrogate: Deformable Gaussian Splatting for Parameter Space Exploration of Ensemble Simulations
Ziwei Li, Rumali Perera, Angus Forbes +5
Exploring ensemble simulations is increasingly important across many scientific domains. However, supporting flexible post-hoc exploration remains challenging due to the trade-off…
Efficient Probabilistic Visualization of Local Divergence of 2D Vector Fields with Independent Gaussian Uncertainty
Timbwaoga A. J. Ouermi, Eric Li, Kenneth Moreland +3
This work focuses on visualizing uncertainty of local divergence of two-dimensional vector fields. Divergence is one of the fundamental attributes of fluid flows, as it can help do…
Parallelize Over Data Particle Advection: Participation, Ping Pong Particles, and Overhead
Zhe Wang, Kenneth Moreland, Matthew Larsen +3
Particle advection is one of the foundational algorithms for visualization and analysis and is central to understanding vector fields common to scientific simulations. Achieving ef…
An Entropy-Based Test and Development Framework for Uncertainty Modeling in Level-Set Visualizations
Robert Sisneros, Tushar M. Athawale, David Pugmire +1
We present a simple comparative framework for testing and developing uncertainty modeling in uncertain marching cubes implementations. The selection of a model to represent the pro…
