Exploring and analyzing the temporal evolution of features in large-scale time-varying datasets is a common problem in many areas of science and engineering. One natural representation of such data is tracking graphs, i.e., constrained graph layouts that use one spatial dimension to indicate time and show the “tracks” of each feature as it(More)
Understanding the temporal evolution of features of interest requires the ability to: (i) extract features from each snapshot; (ii) correlate them over time; and (iii) understand the resulting tracking graph. This paper provides new solutions for the last two challenges in the context of large-scale turbulent combustion simulations. In particular, we(More)
State-of-the-art cosmological simulations regularly contain billions of particles, providing scientists the opportunity to study the evolution of the Universe in great detail. However, the rate at which these simulations generate data severely taxes existing analysis techniques. Therefore, developing new scalable alternatives is essential for continued(More)
Figure 1: Snapshots around a time the tungsten surface is pushed upward by a over-pressurized helium bubble (left), then recoils as the bubble bursts (center, right). In each snapshot, the tungsten voids are indicated in blue, helium bubbles in gray, and the extracted statistics and bubble evaluation details are also displayed. Here, the simulation box is ≈(More)
This document serves as a supplementary document to further expand upon the capabilities of the Ray Graph structure. We first provide some additional examples for 360 • and street panoramas. Fig. S.1 shows some results of 360 • panoramas from two different datasets. These have been created from a Ray Graph traversal which maintains the directional coherency(More)
Atmospheric sciences is the study of physical and chemical phenomena occurring within the Earth's atmosphere. The study entails understanding the state of the Earth's atmosphere, how it is changing over time and why. Understanding how various weather events develop and evolve is often conducted through retrospective analysis of past atmospheric events.(More)
