Abstract
Cosmologists are currently researching the theory of large-scale structures, which are in essence groups of neighbouring galaxies. Recent “galaxy-hunts” have resulted in data for hundreds of thousands of galaxies being made publicly available, and it has become infeasible to isolate large-scale structures by hand from this data. Furthermore, it is difficult for cosmologists to visualise such structures by simply observing the galaxies that comprise the structure; they need a graphically rendered system in which they can change their viewpoint and observe the structure from any position desired. We present a system that identifies large-scale structures from datasets of galaxy information, and then displays the data using OpenGL in such a way that the user can “fly” through space in realtime, observing not only a single structure but the entire dataset and how structures are positioned relative to each other.
