Sparse Virtual Textures
A technical description of my implementation of Sparse Virtual Textures in Gaia Sky
Real time rendering of the Earth in Gaia Sky with surface, cloud and height virtual textures.
Implementing proper virtual texture support in Gaia Sky has been on my to-do list for many years. And for many years I have feared that very item, as the virtual texture mechanism is notoriously complex and hard to implement. However, once working, they are very cool and bring a lot of value to software like Gaia Sky. In this post, I describe and discuss my implementation of virtual textures in Gaia Sky in detail, and provide a thorough examination of some of its most interesting points.
In this post, I’m mirroring the Gaia Sky 3 tutorial I wrote for the official Gaia Sky documentation to use as a rough script for the workshop given in a splinter session of the 2021 DPAC consortium online meeting held on March 17 and 18, 2021. You can find the original page here.

Gaia Sky 3
Dramatic performance improvements and lots of new features in Gaia Sky 3
It’s been a while since I last talked about new Gaia Sky releases. Today I’m doing a recap of the last four releases, starting with
3.0.0. This very verison came out with Gaia eDR3 on Dec 3, 2020. It was a big jump for Gaia Sky, as it introduced a plethora of new features and QOL improvements along with lots of bug fixes and little tweaks. This post goes over the latest versions from
3.0.3, and reflects on what they brought to the table.
Jump to the analysis for each of the versions directly:
A while ago Erwan Leroy, a VFX professional and trainer, contacted me with some questions regarding the catalogs in Gaia Sky. Basically, he was trying to decode the binary format used in Gaia Sky to load the stars using a Python script. Of course, my documentation was lacking in that very aspect, so I walked him through the format and then improved the docs. Today, he has come back to me to share his results.
Gaia Sky 2.2.0
Planetary surfaces, keyframed camera, new scripting and more
Today we are releasing a brand new version (
2.2.0) of Gaia Sky with several major changes and new features. To sum up, github reports 1071 changed files, with 81672 additions and 31763 deletions. Gitlab displays a “Too many changes to show” banner, as their cap is at a 1000 files. This makes it by far the largest release ever, followed by version
1.5.0 in the summer of 2017.
Scripting Gaia Sky
Random thoughts on the Gaia Sky scripting system
Scripting Gaia Sky with Py4J
Gaia Sky has a quite powerful Python scripting system which has gotten a revamp lately. The system exposes an API which can be used from Python scripts to interact with an instance of Gaia Sky running in the same machine (so far). But to understand where we are, we need to know where do we come from.
