Coding Adventure: Clouds

Clouds are lovely and fluffy and rather difficult to make.
In this video I attempt to create clouds from code in the Unity game engine.

I made a mistake at 2:12 in saying that the closest point is guaranteed to be inside the adjacent cells, it’s possible to get arrangements where the nearest point is two cells away orthogonally. This doesn’t seem to occur much as I never noticed any discontinuities in the result, but worth knowing.

Hello, hope you enjoy the video! It was a lot of work getting this far, but definitely still have a long way to go. Clouds are tough! I'd love to hear your thoughts about how they could be improved. Links to all the resources I learnt from are in the description if you'd like to know more. Edit: I made a mistake at 2:12 in saying that the closest point is guaranteed to be inside the adjacent cells, it’s possible to get arrangements where the nearest point is two cells away orthogonally. This doesn’t seem to occur much as I never noticed any discontinuities in the result, but worth knowing. Thanks to everyone who pointed it out.

[@OsUltraBug]

It looks awesome, I would like to know if it would be feasible to actually simulate the clouds as they are in real life (as in simulate condensation, evaporation, etc.). It would probably be too much for a GPU to handle so my suggestion would be to hand it off to a server that would then stream the simulation and it's just a matter of rendering.

[@maxfun6797]

Except this is a huge plane that is placed on the scene, and won't generate realistic, indivual clouds. Can't create other weather phenominons. Good for demo, but does it work for actual games? It does give me an ides though. Using the same method, but individual 3d planes/cubes, but the plotting at and offset from the edge so the fluff doesn't cut off. Then with these individual clouds, different types of clouds can be places near them, and blend them. ... all very heavy effort. Easy to say, hard to do.

[@h1lw]

There was a short clip of the real clouds in the mountain in this video. The clouds were behaving very differently (they had physics) while this is just a 3D texture and not simulated with molecular precision (🤓) (or just acting like real clouds and have physics). There is new techniques (🤓🤓🤓🤓🤓) that have better performance and have better clouds. I hate myself.

[@MrMusAddict]

Excellent work! I have 2 suggestions: 1) If it's possible, I recommend adding a 4th dimension into your noise. That way you can do a 4th dimensional offset, which will simulate condensation and evaporation. 2) See if you can send the terrain data back to the noise function. You can then use the heightmap to prevent the clouds from clipping, and maybe even shape the clouds over the mountain like in your IRL video.

[@timh.6872]

Would be nice, yes, but very GPU-intensive. Would need to map the procedurally generated clouds onto the terrain, which essentially means the cloud sampling fragment shader is running on every pixel. Perhaps just running it per vertex and filtering it would be enough...

[@Alex-op2kc]

Nice find

[@Mystixor]

Just rendering the noise to a texture (2d slice of the center of the clouds (densest area)) and then instead of rendering a shadow map as usual directly projecting the noise onto the terrain as occlusion values in the terrain shader should work out nicely.

As someone with a Masters in Meteorological Physics, this was really interesting to me. It doesn't do a great job of modelling real cloud behaviour, especially in terms of motion over time, but that's understandable since cloud physics are incredibly complex and difficult to calculate. But it did make me understand why a lot of simulated clouds might look and act in the way they do (e.g. mostly confined to a single vertical layer, single uniform horizontal velocity, but good simulation of light effects).

Can you do a coding adventure simulating snow on the ground, packable when something moved over it, using something like this?

[@ClokworkGremlin]

eh... maybe, but you'd probably be better off using something closer to voxel terrain. I believe one of the (PS2-era) Virtua Fighter or DOA games had levels with snow on the ground that would get mashed and deformed by the fighters' footsteps, and it just used a simple heightmap that got knocked down whenever something passed through it.

[@dutchdykefinger]

​@@ClokworkGremlin yeah, a dynamic heightmap sounds like the cheapest solution for sure especially that rudamentary implementation. for a bit more razzmatazz stencil type of shit, you could just project whatever is colliding striaght from the bottom up in orthographic with a hard Z distance limit about as far as you want the deform to be deep. map the things that are further away in Z distance with darker shades of grey to make a heightmap (or lighter, depending on which way you want to go), and map them across the whole rgb range (something like "int color=Math.round(vector.z/zmax)*255"), not overwriting any already set values (essentially projected Z -> B/W color mapping to be short about it). you could even use lookup tables (read: more bump/heightmaps) to make it even cheaper, or or go the other way, and pimp it even a bit more, and allow it to deform terrain other than striaght down,by calculating the inverse angle at which the object approaches it (IE: "player.velocity*=-1" for every axis, and using the outputs to decide where to project the object from, and the factors to which each axis on the target plane should be deformed. (read: the intensity factor for moving the vertices) just mix the 2 maps with regular 2d, as in poking in the pixel data arrays with basic maths (multiplication) could even do with addition/subtraction alone, or even hard setting values, but add/sub wouldn't respect the form of prior deformations as much, unless you made some conditions you can completely avoid using multiplication, and the other (setting) wouldn't respect any old data at all, obviously. but that's merely a matter of preference the geometry may get a bit busy at some point if you want it to look good though, but that's why these things almost always had a hard count limit with modulo on the array index for good old last-in-first-out. or a decay time. tackling that may be a bit more complicated, but i'd opt for something like introducing a view distance falloff for geometry simplification, by keeping multiple mesh/vertex datasets at varying degrees of detail/complexity at hand, using precalculated positions, and bounding boxes of the deformations outside of the range as texture position and size, to fake your way out of it even dynamic unsubdividing is pretty easy if you stick to planes, not harder than calculating pixel or tile array position from X,Y values using the width and height maximums in 2d, as planes have no complexity in the Z dimension whatsoever, it's all still 2d under the hood (akin to "index=(ob.x%w)+Math.floor(ob.y/w)" , or "coord_x=Math.round(ob.x/tilesz)*tilesz" and so on...) all i know is, i would avoid dynamic geometry complexity like the plague, changing from anything but a plane will mess up the heightmap mapping unless you use a ton of witchcraft, and just duplicating geometry as a seperate object is entering a minefield of z-fighting and collision detection problems, easily the 2nd hardest approach (and not even all that cpu friendly either if the whole process is to be done in real-time) they may be more balls to the wall once said and done, but getting there... ugh, i'd rather die of natural causes

[@ClokworkGremlin]

[@feha92]

Seeing how a slider were used to move the clouds, I started wondering about maybe doing the cloud-generating algorithm not in 2d as initially explained, not in 3d as it moved to later, but in 4d. So points are randomly distributed as before, but this time instead of vec2 or vec, it would be vec4(x,y,z,w), and then for each possible point (still vec4) in structure the distance to closest point is encoded like before. But when rendering, only a 3d box is rendered as before (lock the w-value), and as time passes the box is replaced by "moving" through the fourth dimension. This should make the clouds morph in a continuous manner, never going discontinuous, although might look a bit odd for clouds as they might "morph" into existence where it looked to be relatively empty, or out of existence where it was dense (as if water condenses and evaporates out of thin air).

[@SirMonkeybutt10]

This is actually a really out of the box good idea, did you come up with this or did you see this done somewhere (no offense)

[@feha92]

@@SirMonkeybutt10 I thought of it myself, and I realized later that its actually a bad idea for clouds (technically, I realized it halfway into writing it, as the last note shows, but by then I had already invested effort in writing it). Granted, the idea is sound if you want a continuous morphing geometry, but that is decidedly _not_ how clouds move irl :p I also have no idea how it would actually look, as you would either have 4-dimensional triangles that would somehow need to be rendered, or be treating the fourth component as solely a time-axis (and in that case need to re-generate the geometry each step in time).

oh YES. now thats something i wanted to see :D

Your videos are always intriguing and that plane part at the end was so relaxing. And the cloud break was a nice touch too lol

BEAUTIFUL gameplay at 11:45, props to you. The atmosphere is incredible, wow. I've never had the chance to experience such tranquillity in a game.

I'd love to see them react to terrain or other colliders. to get a 'clouds rolling over a mountain' effect.

[@World_Theory]

I … had my doubts about the realism of this ‘distance from a point’ thing, but the end result look pretty good.

[@codestrudel]

This is just amazing. I am impressed by your talent to observe nature and reproduce it in code. Your are truly the Bob Ross of Computer Science. Much love from Germany and thank you for your outstanding and calming content.

[@OriFrish]

You make it look so simple, and yet, to understand what should be the correct mathematical algorithms and how to implement them... Requires a genius mind. Absolutely stunning, well done!

This looks great! However, with clouds they actually also obscure light. Maybe in a future video you could try to make these clouds cast shadows? Not important, but would be an interesting challenge for sure.

Detail Noise Scale and Weight really made the clouds shine! Awesome work, keep it up :)

[@ADunwoody0403]

Absolutely brilliant! I've been wanting to do my own ray marching cloud shader for many months now ever since I was blown away by Red Dead Redemption 2's clouds. This is a great guide to get me started :D. I'm very curious to see how you tackle the performance limitations. Love the videos Sebastian, your style is phenomenal, keep it up. Nice to see a fellow South African producing such quality content.

"Obviously, there's still so much more to do! " **By the time, he created a superior version of Microsoft's flight sim, from scratch, in one week or so**

[@gnupfo]

The flight sim he made is not: -superior to Microsoft's: it has a very limited area, only one plane which only has one function, very monotonous terrain, etc. -from scratch (he said he took a premade plane model and controller from the internet and he used his own premade terrain generation) It does have amazing visuals though, on which an asthetics-based (rather than function-based) sim could work on.

@@gnupfo You must be fun at parties.

[@emberdrops3892]

[@silvertheelf]

11:50 Idk why the scene looks like something out of the mountains of madness if it was a movie. Know what, I’m gonna take it all and use it to design my own clouds, and I will have terrain generated by a hydraulic system, I will have animals that will live in an advanced ecosystem... but they can also fall off the world because I just want to see things falling... and I will use boids for herds and flocks of animals.

Yeah sure, just let me... *Grabs a cloud sprite and slaps it into a project* Done.

[@raw238]

This is procedural code made buddy...that means you can make, control and change/chain it with any of the infinite possibles and shapes, colors n sizes the world has to offer in real time....that means you can do sky/cloud timelapses for video , weather sim and games ofcourse because you have probably made a clouds sim program with this.

It doesnt take too long to figure out, unity itself has some great official tutorials on getting started with the language

[@640kiboughttobeenough]

@@louisgreenland4446 If you're a Java programmer, yes, it's easy to switch to it. It has better performance than Java due to using a compiler rather than an interpreter. I don't know where I could C#, so I don't really know much. Though, I haven't seen any C# compilers for Linux either.
