Abstract
Spherical coordinate systems, which are ubiquitous in astronomy, cannot be
shown without distortion on flat, two-dimensional surfaces. This poses
challenges for the two complementary phases of visual exploration -- making
discoveries in data by looking for relationships, patterns or anomalies -- and
publication -- where the results of an exploration are made available for
scientific scrutiny or communication. This is a long-standing problem, and many
practical solutions have been developed. Our allskyVR approach provides a
workflow for experimentation with commodity virtual reality head-mounted
displays. Using the free, open source S2PLOT programming library, and the
A-Frame WebVR browser-based framework, we provide a straightforward way to
visualise all-sky catalogues on a user-centred, virtual celestial sphere. The
allskyVR distribution contains both a quickstart option, complete with a
gaze-based menu system, and a fully customisable mode for those who need more
control of the immersive experience.
