Atmospheric Scattering (and also just faking it)

This project tackles adding atmospheric scattering to our procedural worlds, using both a physically accurate model and a hacked together pile of garbage approach. Depending on your use case, if you need photo realism or a more exaggerated look for your 3d world generation, one or the other may suit you.
This is the 6th in a series of 3D world generation tutorials. In the previous tutorial we covered some texturing technique, and in this project we'll build on that and improve it with an atmosphere to help with the overall look.
Just treat this as a jumping off point for your own projects, there's lots of ways to do this, but if you want to understand how some of the bigger engines do it, or how to cobble together some shaders on your own, this can help. Especially if you're doing a lot of procedural generation for yourself.
Full source code for the project is available, so if you're interested in fiddling with the code, screwing around with it, or improving it.

I would pay and I think many would, if this would be implemented in Unity or UE4! Amazing work!!

What a wonderful name
Hey! This is awesome. By the way, there is a vs-code plugin which lints glsl code which is stored in js strings. I can find it for you if need be.

Best one yet. Was just playing with the unity hdrp. That does this on a more local level. Would love to build planets.

Hey SimonDev, really interesting video, did you manage to implement this into something like Unity? If so where could I find this? I tried your github but could not find anything, cheers in advance.

You could port it to Unity, there's nothing JS specific here. It's all in github, under ProceduralTerrain_PartX for whichever video.

@@simondev758 Thanks for the reply, ill give it a shot, if I did manage to get this into unity, how would I go about giving the atmosphere a custom colour prehaps? (The first version you showed, the physically simulated atmosphere). github.com/simondevyoutube/ProceduralTerrain_Part10/blob/main/src/scattering-shader.js (Is this the shader?), would I just translate this into unity's shaderlab code I am guessing and apply the shader to a material? Many thanks
You didn't explain what mesh you apply the shader to and how
Great work Simon, as always. I'm having a hard time trying to implement the scattering in a small project just for fun. Your custom shader works really good, but when I switch to the _ComputeScattering function, the effect is only visible when you are really close to the planet. I'm trying to figure this out, but I wonder if you encountered the same problem. Cheers!

Might be an issue of scale, that scattering is meant for actual earth sized distances.

@@simondev758 I was trying to implement this is unity. I believe the problem is that you have the primary ray starting at the camera position rather than the edge of the atmosphere. So rather than setting the primaryStepPosition to 0, set it to the first ray intersection point with the atmosphere.
Can you use this scattering method on a plane terrain
Awesome video! Is there a way to do this with unity shader graph?

I'm not at all familiar with Unity's shader graph, sorry.
this isnt a tutorial you didnt show how to do it like atall you just pulled up a bunch of complex code highlighted abit of it was was like here lmao basically a presentation of your working and showing a hint of how you did it

Depends what you define a tutorial as. Sounds like you want me to step through every line, which is fair but not what I do. I'm used to showing the process, the ideas, and leave the implementation to other people.
Has the source code been taken down? I don’t see it on your github.
