“…We visualise both the particle and gridded data using frelled, as described in Taylor (2015). We produce gridded P-V cubes of each simulation for each timestep, and although these are used in the automatic parameter measurements it is obviously impractical to visually inspect the resulting 5,400 data cubes.…”

Isolated Hi clouds with no optical counterparts are often taken as evidence for galaxygalaxy interactions, though an alternative hypothesis is that these are primordial 'dark galaxies' which have not formed stars. Similarly, certain kinematic features in Hi streams are also controversial, sometimes taken as evidence of dark galaxies but also perhaps explicable as the result of harassment. We numerically model the passage of a galaxy through the gravitational field of cluster. The galaxy consists of SPH particles for the gas and n-bodies for the stars and dark matter, while the cluster includes the gravitational effects of substructure using 400 subhalos (the effects of the intracluster medium are ignored). We find that harassment can indeed produce long Hi streams and these streams can include kinematic features resembling dark galaxy candidates such as VIRGOHI21. We also show that apparent clouds with diameter <20 kpc and velocity widths <50 km s −1 are almost invariably produced in these simulations, making tidal debris a highly probable explanation. In contrast, we show that the frequency of isolated clouds of the same size but velocity width >100 km s −1 is negligible -making this a very unlikely explanation for the observed clouds in the Virgo cluster with these properties.

“…blender is an open-source alternative to mayavi that offers a nearly unlimited set of options and tools, but at the price of an extremely steep learning curve. From that perspective, recent efforts like frelled (Taylor 2015) and astroblend (Naiman 2016) aiming at bringing blender closer to astronomers are certainly worth mentioning (see also Kent 2013Kent , 2015.…”

The concept of the x3d pathway was introduced by Vogt et al. (2016) as a new approach to sharing and publishing 3-D structures interactively in online scientific journals. The core characteristics of the x3d pathway are that: 1) it does not rely on specific software, but rather a file format (x3d), 2) it can be implemented using fully open-source tools, and 3) article readers can access the interactive models using most main stream web browsers without the need for any additional plugins. In this article, we further demonstrate the potential of the x3d pathway to visualize datasets from optical integral field spectrographs. We use recent observations of the oxygen-rich young supernova remnant 1E 0102.2-7219 in the Small Magellanic Cloud to implement additional x3dom tools & techniques and expand the range of interactions that can be offered to article readers. In particular, we present a set of javascript functions allowing the creation and interactive handling of clip planes, effectively allowing users to take measurements of distances and angles directly from the interactive model itself.

“…Recent innovations in the computer graphics and gaming industry can be exploited for this multi-pronged approach to data investigation [5,11]. In addition to increasing the rate of information exchange within scientific collaborations, as technological advancements in graphics and gaming progress, innovative methods for discussing scientific concepts with the general public can be developed [12,13,14,15,16].…”

“…In astronomy, the work of [19,11] serves as an introduction to many of Blender's features for the field, and focuses mainly on methods to generate physically accurate artistic models of astrophysical objects. While [19,11] provides initial methods for viewing observational and simulation data, the FRELLED 1 package provides a detailed interface for uploading and interacting with multidimensional observational and simulated datasets [5]. FRELLED is styled for the extraction of HI sources, which makes use of Blender's volume rendering capabilities and includes methods to record source information, decreasing extraction times by more than an order of magnitude.…”

“…With the growth of multi-dimensional astrophysical datasets from simulations and observations, the need for greater interaction with such complex systems has also increased [1,2,3,4,5]. Not only do larger simulations and observation programs necessitate efficient ways to investigate their data [2,6,3], but comparison between the outputs of multiple astrophysical codes and observational surveys requires a cross platform application capable of processing numerous data formats [2,7].…”

The rapid growth in scale and complexity of both computational and observational astrophysics over the past decade necessitates efficient and intuitive methods for examining and visualizing large datasets. Here, I present AstroBlend, an open-source Python library for use within the three dimensional modeling software, Blender. While Blender has been a popular open-source software among animators and visual effects artists, in recent years it has also become a tool for visualizing astrophysical datasets. AstroBlend combines the three dimensional capabilities of Blender with the analysis tools of the widely used astrophysical toolset, yt, to afford both computational and observational astrophysicists the ability to simultaneously analyze their data and create informative and appealing visualizations. The introduction of this package includes a description of features, work flow, and various example visualizations. A website -www.astroblend.com -has been developed which includes tutorials, and a gallery of example images and movies, along with links to downloadable data, three dimensional artistic models, and various other resources.
