A nice milestone for #Geomancer. Elevation is generated with noise in webgpu as part of a graph of tasks, which I'm only visualizing to debug noise output which is used elsewhere. Excited to crash continents together as a next step. #threejs | #procgen https://geomancer.kenny.wtf/ - ThreadSky

Looks very natural, great job! Do you preprocess/map the noise somehow?

kenny.wtf•2 days ago

thank you!!! its 3D perlin noise sampled from world coordinates thats is warped pretty heavily (domain warping). I think the reason it looks so natural is that I stole the color palette from some NOAA map’s legend lol

Haha, yeah, the colors do make a difference :)

But I'm talking more about the shapes: you have tons of things that looks like hotspot island chains (like Hawaii), elongated peninsulas, bays that look like glacier erosions, etc, etc. Could you talk a bit more about the domain warping you use?

Right, I think I mostly lucked into it. Basically the main thing is that I rotate the (normalized) coordinates before sampling the FBM for the warp factor. The rest is just adding random scale and offsets.

It's extremely unscientific 😀

Awww, nice! The results are so incredible for such a simple trick :)

that's so kind :)
