During the last months I have been working on a QOL improvement for Gaia Sky video production. Currently, Gaia Sky offers a couple of ways to persist and reproduce camera behaviours: scripting and camera paths. Scripting offers a high level API which allows for the interaction and manipulation of the internal state. Conceptually, a running script is no different from a regular user. A script runs in its own thread and, like a user, interacts with Gaia Sky's core through the event manager, a message-passing entity which encapsulates the core functionality.
This time around we've had a slightly longer development cycle so Gaia Sky 1.5.0 ‘Jumbo Summer Release’ is here with a ton of new features, enhancements and bug fixes. Most importantly, we have essentially refactored the way star catalogs are handled, so that we can now stream data from disk when it is needed. Also, we've been working hard to make better use of the GPU and we are proud to announce that we've increased the performance fourfold while being able to display many more objects on screen at once.
Gaia Sky is here again with a brand new release packed with new features and bug fixes. Here are the most important:
Today, 26 September 2016, the Astronomy Picture of the Day (APOD) features a video we have prepared with Gaia Sky at the ARI/Uni Heidelberg. The video itself shows a flight from outside of our Milky Way galaxy to the Sun and then a travel through the Solar System towards the vicinity of the Earth, displaying in this journey a little over 600.000 stars from the TGAS part of Gaia Data Release 1.
