Lagrange - Procedural Planet Builder 
A passion project that I’ve been working on for a long time, the culmination of my fascination with our universe!
My goal with Lagrange is for it to become a spiritual successor to the wonderful Chrome experiment PlanetMaker that I had lots of fun with years ago. I wanted to be able to create more detailed planets, to have more control over its surface and features, and this is where I’m at today!
Try it here: Lagrange - Procedural Planet Builder
You can also check the source code on my GitHub, contributions are welcome!
I’m also looking for more translations if you’d be willing to help out.
Current features
- Star-like lighting & lens-flare, for a slightly more realistic environment.
- Procedural surface generation, using a combination of fBm noise, metallic-roughness, bump-mapping & color-ramp for distinct terrain. Includes clouds as well.
- Basic biome generation with three modes: realistic, pole-to-pole, or full noise. Each biome has a given color, as well as temperature & humidity scales.
- Atmosphere customization: allows to change the look of the atmosphere given either a hue value, a color tint, or both!
- Ring system: add one, two or more rings around your planets, with each ring having its own parameters
- Exportable planets, using the glTF format, that can be imported in other apps such as Blender! However, it does not include the atmosphere, as it’s a custom shader and glTF doesn’t support it.
Some examples from the GitHub page
Next steps
- I’m currently working on a full rewrite of the shaders using TSL, as WebGPU seems to be moving forward nicely in terms of adoption (and it’s a very interesting challenge!).
- Afterwards, I have many updates planned: cracks, craters, biome-based bump mapping & noise adjustments, and more!
- Eventually, I’d like to create a galactic map akin to NASA’s Eyes on Exoplanets – NASA/JPL project, although it won’t be for a good while.
I hope I didn’t write too much… In any case, thanks so much for reading, and I hope my little project is interesting enough to showcase here!
