The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Real-time planetary cloud rendering without atmosphere
Real-time planetary cloud rendering using cascaded deep opacity maps and mipmapping. Resolution 960x540, framerate 20 fps unless shadows are long. Using octaves of 643 Worley noise and curl noise for the global cloud coverage 512x512x6 cubemap. Source code: cloudsonly.clj

Cloud rendering with deep opacity maps without atmospheric effects
Source code: atmos.clj.

Volumetric clouds with exponential sampling and mipmapping
The source code of the main program is in etc/planet.clj. It is Clojure code but it is mostly Java calls using LWJGL and OpenGL shaders. The cloud shaders are in resources/shaders/clouds. I recommend Sebastian Lague's video on volumetric clouds to get started. Here is my implementation of a cube filed with clouds: etc/cloudcube.clj.

Cloud layer implementation
Cloud layer implementation using OpenGL shaders. Unfortunately the performance is not great and the clouds are repetitive when viewing from above. Also there are artifacts in zenith and nadir. Let me know if you have any ideas/suggestions! The shaders are here.

Worley noise rendered with multiple forward scattering
Prototype Worley noise rendered with multiple forward scattering (Harris, Lastra). Prototype using OpenGL and Clojure (see github.com/wedesoft/sfsim25 for remaining code).

The Orbiter space cimulator I
Orbiter 2016 is a brilliant game. I am currently trying to do a small space simulator in Clojure (https://github.com/wedesoft/sfsim25) and I probably should take a look at the Orbiter source code.

Reentry – An Orbital Simulator
Maybe not surprising at all. The author open-sourced Orbiter in 2021 [1]. It's MIT [2], so anyone can pick up from where he left off and create a commercial version:
[1] https://www.orbiter-forum.com/threads/orbiter-is-now-open-so...
[2] https://github.com/orbitersim/orbiter/blob/main/LICENSE
- Would anyone like to build an Open Source KSP-like thing?

Open-source wind or solar power simulation
Also if you want to work on wind based simulation maybe this project might interest you https://github.com/orbitersim/orbiter The flight dynamic model is not super accurate and the author is not using the off the shelf library like jsbsim so a lot of improvements are possible.

Think you guys might appreciate this :)
Still the same, but now it's gone open source, hoping for a quicker development by the community now :)

PSA: Orbiter vs "OpenOrbiter"
"OpenOrbiter" is a misnomer, because Orbiter is already open and under MIT. I want everyone to know and understand that the real Orbiter repo, with commits being directly made by the good doctor is this one: https://github.com/orbitersim/orbiter

Games I can contribute too.
If you like space there is vega strike , pioneer and orbiter.
- Is there an explanation of the Orbiter codebase, like what part is the "main" where it all starts kind of thing?
- Orbiter launcher seems to have low text quality?
-
James Webb Space Telescope successfully deploys antenna
As a sidenote, it looks like the author released orbiter on GitHub: https://github.com/orbitersim/orbiter
