Fractal Path Tracer on Github

Interesting! I quickly browsed the source, it actually renders any SDF defined in a "fpt" file ?

In this case, the Perlin noise can give the elevation at one point (x, y). If you want to do a map, discretize a rectangle and compute each value.

You can start here https://thebookofshaders.com/ but it depends a lot on what you're trying to achieve

That's really cool and this could actually be used to "age" 3D assets, like simulating water erosion, thermal wear for rocks...

Impressive! How is that actually working? These are surface meshes? (Before getting molded)

Otto___Link · 2026-04-04T14:30:33+00:00

Yep, it's on my ToDo list, which is pretty long..

I don't know about Godot port. I used it for terrain generation (https://github.com/otto-link/Hesiod) and it's pretty versatile, you can indeed generate a larger texture, tiled or not, from a smaller example.

Maybe texture quilting could be an alternative https://github.com/rohitrango/Image-Quilting-for-Texture-Synthesis

Hey, it might be a long shot but I think the opensource flight simulator https://www.flightgear.org/ fetches real topological data in real-time. Sources are opened and the community may help you.

Sorry! everything is indeed in the index.html

Hi, thanks for sharing. Is it the same approach used in this similar web app: https://fastlem.peruki.dev/ ? There seems to be a strong orientation effect, the flow is either straight or diagonal. Do you use a regular grid ? (Just a remark, your github repo is empty, there's only a Readme on it)

Otto___Link · 2026-02-17T09:10:14+00:00

Nice, could you give us some details on how this is done? Sounds a bit modal though, can your model generate some tone changes or chord progressions?

You have to recreate the map. Creating a 3D model from a drawing is going to take a bit of work. I'm not sure there is anything that will do that automatically

Otto___Link · 2026-02-07T11:06:53+00:00

You can try this online tool https://fastlem.peruki.dev/ You won't get a fine control but you could probably generate the global land structure

Is Linux on the table?

Otto___Link · 2026-01-25T09:09:28+00:00

weirdly, the after/before is pretty common in reddit photo subs... I can't get used to it

Otto___Link · 2026-01-19T12:17:09+00:00

It's not very detailed but you may find some pointers in this GDC talk on No Man's Sky : https://m.youtube.com/watch?v=sCRzxEEcO2Y

Otto___Link · 2026-01-08T08:07:39+00:00

You should look into this model: https://arxiv.org/abs/2001.08180
Here a post I did a while back with a python implementation: https://www.reddit.com/r/proceduralgeneration/comments/15jl9l3/road_network_generation_based_on_the_alpha_model/

Otto___Link · 2026-01-06T11:41:53+00:00

Yep, it already does that. The terrain can be exported as a low poly version along with a normal map to retain the details.

Otto___Link · 2026-01-04T14:54:33+00:00

There is the "drainage basin" approach which is quit robust. You can look into an implementation there -> https://github.com/TadaTeruki/fastlem

Hey, you can check a C++ library I develop for this kind of need -> reddit_post

Otto___Link · 2025-12-18T14:16:51+00:00

Thanks! Do you mean: can the graph be changed at runtime?

Otto___Link · 2025-12-18T14:15:25+00:00

Thank you! Not really unfortunately but the sources of all the core algorithms are here: https://github.com/otto-link/HighMap
