    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.

      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.

    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.

      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.

      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.

    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).

      To be fair, I dont think this has anything to do with "being bad at coding". Coding/Programming itself is accually quite easy.

    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 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).

    One of your coolest videos. Another interesting graphics idea are Shadows. You can get really deep with that stuff. Shadow techniques/algos to create nice realistic soft shadows, others to capture contact shadows (small shadows not picked up by normal shadowmap techniques) and so on. It would be really interesting and unique look especially with your amazing style of videos. Also...
    would be cool if you do this stuff in URP, since the built-in/legacy render pipeline is in fix-mode only, the main render pipelines are URP/HDRP now.

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

    • @ClokworkGremlin
      @ClokworkGremlin 4 года назад +15

      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.

    • @klontjespap
      @klontjespap 4 года назад +2

      ​@@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
