Supercharging Exoplanets

A short report on the new developments in exoplanet datasets in Gaia Sky

20 minute read

A couple of years ago I wrote about the procedurally generated planets in Gaia Sky. In this post, I provided a more or less detailed technical overview of the process used to procedurally generate planetary surfaces and cloud layers.

Since then, we have used the system to spice up the planets in the planetary systems for which the Gaia satellite could determine reasonable orbits (see the data here, and some Gaia Sky datasets for some of those systems here, including HD81040, Gl876, and more).

However, with the upcoming Gaia DR4, the number of candidate exoplanets is expected to increase significantly, rendering the “one dataset per system” approach unmaintainable. In this post I describe some of the improvements made with regards to exoplanets in Gaia Sky, in both the handling of large numbers of extrasolar systems seamlessly, and in the brand new, improved procedural generation of planetary surfaces and clouds.

Huge Refactoring in Gaia Sky: ECS

Moving the old inheritance hierarchy to an entity component system

In these last few days I have merged a huge internal refactoring into Gaia Sky’s master branch. This refactoring has been cooking for several months and has adapted or completely replaced virtually every piece in the code base. Read on if you want to know more.

Variable Stars and New Render Systems

What is currently going on in Gaia Sky development?

In the past few weeks I have been implementing a couple of features into Gaia Sky. The first is the addition of variable star rendering. The second is the re-implementation of all point cloud render systems to use actual geometry (triangles) instead of point primitives. This post briefly offers a preview of these features.

Gaia Sky 3

Dramatic performance improvements and lots of new features in Gaia Sky 3

10 minute read

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 3.0.0 to 3.0.3, and reflects on what they brought to the table.
