Minecraft uses a newer technique now, where they mix perlin noise with manually entered spline points, which gives them more control and more realistic and less repetitive terrain. Henrik Kniberg (minecraft dev), has a great video about it called "Minecraft terrain generation in a nutshell"

This is some top-notch shit, and it's refreshing to see something new added to this scene, right around when I feel like many people are finally familiar with the general trick of Minecraft-like terrain generation.

This video rivals 3blue1brown in quality. Absolutely jampacked with information and visualization, while being explained perfectly.

thats one hell of an opener, and i absolutely love it

that "not 3, but 2" is a golden defying expectations line.

Finally, someone who thinks perlin looks ugly. Also I unintentionally did the gradient method in one of my own programs and I have a good optimisation tip, I stored the gradient function (an in the video was x/x+m) as a gradient at the bottom of a texture I was using in the rendering process, its a small performance improvement and probabally slower unless your allready using an image in the process, but if your gradient functions are more complex and expensive it could be ever so slightly faster. One downside was that scince it was stored in an image it had to use a byte to store its value so you only had a gradient "resolution" of 256 this was barely noticeable though.

@DreadKyller

26 күн бұрын

I mean 16-bit images are a thing, so you could use a different image format and remove the 256 resolution limit. It's also worth noting that instead of an image you could store a more generic 2D array of values (Or if on the GPU a buffer).

My thoughts exactly 😂

Insanely high production value, very snappy, and good writing! Genuinely surprised your channel isnt bigger, i feel like im buying in before it skyrockets

Just the best video quality ever. This is where I would obsessively gush over every stylistic, audio and animation detail I noticed, but that would take a **lot** of text just to tell everyone (especially the creator) what they already know. (the derivitive robots are just the best though)

This showed up in my recommendations sandwiched between 2 geology videos. I was very confused for a minute.

I am an IB student from Spain and one of our asighnments to pass is to do a simplified version of a scientific paper on any subject, this video has helped me finnaly figure out what to write it on! Thank you so much!

I did not expect to finally understand how upscaling works so well on a video about generating mountain terrain. Everything else you explained made sense too, you do an excellent job at it!

Your videos are by far some of the best on KZread. You deserve so much more recognition than you get. I love your videos so much

So glad this was in my recommendations - It was very well explained for any level of prior knowledge so it filled in any gaps I had without boring me when it covered the parts I was already familiar with. Well done, looking forward to more!

"Not 3, but 2 techniques" yep I'm subbing that's all it took

The animation's on this are just mind-blowing. Awesome video!

I wasn't expecting a video this high effort about random noise, but I'm pleasantly surprised. Subscribed. ❤

As a terrain artist, the DLA approach really peaked (hah) my interest. Fractal Perlins just don't cut it, although indeed much more interesting than plain Perlins, they still have that "CGI" feel to them. I think the DLA approach offers a really solid base shape which you can tweak and augment further without a lot of hassle. Do you happen to know if such an algorithm is resource intensive and/or easy to code? An alternative method, which I think you could combine with Perlin and Voronoi cells, is to cut out rivers and valleys in a select area of your terrain. You'd have to somehow ensure the edges of your Voronoi cells all have the same elevation, so the water would flow to a common lowest point, but then you could (I think) do partial water simulation, cut valleys, and have great mountain shapes. If interested, I have a timelapse of such process on my channel! As for using plain old hydraulic erosion, imo that only works if you do a proper terrain simulation, so it doesn't appear feasible to me at the moment. You'd need different layers of rock to be simulated, as otherwise all terrain is eroded equally, and in the end it would still look artificial (just search "World Machine Mountain" and you will see the flowlines of the erosion and shapes all are similar).

your explanation of gradients is one of the best i’ve ever seen. really impressive for a video where that isn’t even the main goal.

this is literally my niche! i am a minecraft world generation nerd who has struggled with this exact problem, and i found the exact same gradient blog post you mentioned! great visualization!

For such a simplistic approach, I really like the results of the diamond-square alg

Great video, thanks for making high quality educational content! I'm an experienced graphics programmer but didn't know about the gradient trick and DLA terrain... Until now!

Haha the funny internet dog is teaching me fascinating mountain generation techniques, what a wonderful time to be alive

Holy hell, this is a very good visualisation. Hope you keep this style of animation for future explainers, preferably shorter so it's not too onerous for you! Subbing for more : )

How tf is it even possible that such stuff is shared with literally everyone for free? I can barely imagine how much time and effort was put into producing such high-quality content.

The visuals on this video, and how tightly they sync with the narration, is astounding. Oh and the sound design, like those small chimes that play when one of the visuals has changed slightly. There's something special going on here.

Even for a complete novice to just coding in general, I love how this video takes concepts that I am familiar with, like Grad operators, and fractal crystals, to produce something we all love: spiky mountains

This is a great balance of deep technical dive with accessible explanations and amazing visuals. It no doubt took ages, thank you and please do more!

i like how in the beginning the snow and rocks on the mountain looks very low quality, and then at the end it's near photorealistic

normally i can't handle math intensive videos w/o dozing off but your presentation is equally visually appealing as it is well explained !

Incredible video. I've never done any terrain generation or even computer graphics work before, but I was hooked all the way through. As others have said the humor was witty and the visual choices (like the two robots at 7:05) were great, but I wanted to highlight a moment at 6:32. When you introduce and start explaining finite difference approximation, the immediate question that comes to mind for me as a viewer is "why not just make the difference as small as possible?" And immediately you have an extremely intuitive and expressive animation showing both the reason that doesn't work (the pixelated zoom-in) and what would happen if you did it. That detail could have taken 5+ minutes to explain, or could have just been skipped and left as an unresolved anxiety, but in 3 seconds and half a sentence I've already had my question answered before I even asked it, built quality intuition about what's going on, and feel comfortable that I've grasped the concept. Seriously top-tier stuff here.

One of the best and most curated video I’ve seen so far

I LOVE procedural generation and the quality of production got you an instant sub. I already knew quite a bit about terrain gen yet I learnt a lot from this video!

Thanks for clarifying this!

Wow. Incredibly high quality video and very full of information. I hope to see many more in the future! Keep it up!

This is very interesting to me. About 20 years ago I wrote a world generator program that started with an icosahedron with randomly perturbed heights, then calculated the average along the midpoints and perturbed that by half as much (I should note that in all cases I was using spherical rather than cartesian coordinates), then calculated and perturbed the midpoints of the of the lines between every pair of now-neighboring points, etc. for like eight or nine generations. There were two problems: 1, I ended up with a ball that looked nicely random but didn't look very "world-like", because it didn't really produce mountain ranges or plains, and 2) the technique didn't generate rivers or inland lakes, if I set a sea level elevation and just said :above this line is dry land, below it is ocean" it just tended to produce islands with a big peak in the middle. I played some games with modifying the elevations (specifically, I simulated the impact of meteorites that depressed the terrain in a large circle, and raised the terrain at the "rim" of the "crater") and was able to get something approximating "mountain ranges" (crater rims) and "plains" (crater basins), but still no rivers or inland lakes. I started trying to simulate erosion to determine where rivers and lakes might form, but ran into difficulties and stopped working on the project. By the time I got interested in it again I had lost the original source code, but I recently found it again and was wondering what I could do to improve it. I'm now considering using the fractal Perlin noise technique to see what that does.

Ah, yes. Who hasn't experienced the moment where, in the midst of conquering the powers of nature herself by scaling the highest of mountains, a wild sentient literate snow dog appears to you and takes you to an abstract world to explain how mountains can be accurately generated by computer software?

OMG I randomly got here and thought that you must have millions of subscribers with such an awesome production quality. This is exceptionally good and cute to fully animate your character talking to the audience as the geometric shapes. You can fill the pure talking time with these animations when there are nothing else to show at the moment. I love the smooth movements and I really hope your channel gets big! EDIT: Oh and not to forget to mention that the explanations with these nice and smooth animations with the distinctive sound design make it also very easy to follow and understand every point easily. I was really surprised how much effort was put into all these graphs, transitions and interactions so it felt like a movie, instead of still images with little 2D/Flash animations to make it wobble or something. These were fully made in this 3D environment, as far as I can see.
