Our system design is motivated by the need to simultaneously observe multiple data modalities. The main output from the cosmological simulation is a set of particle data, where each particle represents a dark matter parcel which coalesces into larger structures over time. Next, the data is run through a halo finding algorithm (Rockstar [1]), which...

... quantitative analysis provides important statistics for understanding found halos, a 3D view of the simu- lation particles can show the physical behavior of the system in a more intuitive way. Figure 3 shows a 3D rendering of the parti- cles colored according to their velocity magnitude (blue particles are moving slowly while green particles are moving quickly). We make the particle view fully interactive; users can control various settings, such as the viewing angle using standard camera controls (rotate, zoom, pan, etc.) or the color and transparancy mapping using a built in transfer function editor. ...
