I’ve never thought about using DLA for generating terrain, that’s a cool idea. Excited to experiment with it! Also, your visualizations and style are amazing, great work! :o
@@yodaman8015 Feel better for having given your insightful $0.02? why are you under the impression that I care what your opinion is. Your neg should've stayed in the drafts, mate. Go bother someone else.
I'm like 4 minutes in and I'm so engrossed in the information that I didn't even realize how much effort you put into these graphics. 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. These sorts of videos are what give me the motivation to continue my study and hopefully one day be able to code stuff like this myself. I'll probably reference this video in the future, so I'll be back when that time comes. Absolutely amazing video, 10/10
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?
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"
You can also see a talk by the creators of No Man's Sky and see how many techniques they apply. Just, don't market your new game as an expansive universe of repetitiveness
Thank you, now I have an excuse to rewrite my entire terrain generator for the 4th time! YESS! I'm so happy about this! Seriously though, this is great.
Hey I'm only a couple minutes into this video but it's already really incredible, the visualizations, everything -- so so good!! Fantastic job. Can't wait to see more!
ok finished the video -- wow!! You covered so so many topics (a lot of which I recognize from my graphics classes) in such a short time, and you did it incredibly well!! This is a seriously impressive bit of educational content, man. That's absolutely awesome!
Incredible video, Josh. Not only was the multi-noise algorithms clear and easy to understand, but extremely entertaining. The production quality is fantastic, and it makes the content even more engaging. Looking forward to more videos like this. Subbed. 👍
This is exorbitating quality from a TH-cam video. I may guess how you create all the animations, but It still blows my mind, I'd really like to know more. You're one of the best Computer Graphics content creators on platform, keep up!
Insanely high production value, very snappy, and good writing! Genuinely surprised your channel isnt bigger, i feel like im buying in before it skyrockets
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.
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.
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).
I believe that perlin CAN look nice, if you completely rewrote the algorithm. However, it sucks right now. Looks like something a computer generated. Oh wait, a computer DID.
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)
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.
Amazing video! CGI was amazing, and the explanations were super clear! I’m working on a terrain generator for my game, and I’ve gotten some new ideas after watching, thanks for making this!
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!
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 : )
this channel is just crazy with how underrated this is when i first saw this video i thought the channel had at least a few million subs with how good the quality was.
I love how the little animations in your video not only look nice and mix things up neatly, but also show the viewer that "Hey, this guy really know what he's talking about with all this creating good-looking visuals stuff"
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!
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!
This is the first video from this channel that I came across and I just want to say that the quality of the animation and visualization of the algorithms is simply amazing.
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).
Hi, I wrote an implementation of DLA based of this video; it's not too difficult, but, depending on how you do it, may need quite a bit of optimization to run smoothly. Hit me up if you've got any questions
How about incorporating ground composition into the fractal perlin calculation? Steep soil erodes faster than steep rock, sandstone erodes faster than granite, etc...
This is incredible! I just learned dendrite formation, diffusion limited aggregation in my Materials Science class and now it pops up in a terrain generation video I’m watching for fun! It’s crazy beautiful. Thanks for sharing. 9:42
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!
All of the visuals in this video are so well done. I found myself watching some scenes over and over just to track the dog's mouth with the narration. It's impeccable how well animated this is!
Amazing video! I only wish you'd change the thumbnail to make it look more alluring? Your dog character in particular has been a really distinct signature of your channel (not to mention they look very adorable 🥺) and I know a lot of people will be more intrigued to click if they see them in the thumbnail. (Maybe put on something like the scene where they're explaining to the three regular polyhedra?) I really hope you have more viewers and supporters in the near future! ❤
The attention to detail in the visualizations is incredible. I'm a graphics programmer myself and I was delighted by how much explanatory weight your animations hefted (clarifying and fleshing out the breezy voice over). You have a real talent for visual elucidation. This seems like an insane amount of work per minute of video. I hope it is worth it for you, because this really is top tier educational material.
"Doggo of wisdom, what is your wisdom?" "Many people have dreamed of summiting the highest mountains, but there exists a strange sort of person that dreams of generating them instead."
This is BEAUTIFULLY animated AND explained! I feel like I could actually follow you, which is rare for most complex math videos. You're an absolute gem.
9:49 I'm curious what this looks like when bias is introduced into the motion of the pixels. This algorithm seems to want purely random walks, but if it were slightly biased to be center-seeking it could speed up the process while losing out on its other built in properties. Likewise, having multiple bias points to have things gravitate towards could end up with something neat. I'll have to do some tests here with a quick hack job test to see the results.
After some tests, I had to un-bias the bias for when points were being manipulated to move towards the center. Since the pixels live on integer grid space, movement was also integer based despite the direction vector being floating point. To remove the bias, I put in a random magnitude pass for the direction to succeed in moving towards it for each axis, which did bring back the uniform look. Too much of this injected center-seeking bias makes it appear more lattice like, as expected.
I don't know if I've ever seen your videos before, but this information is EXACTLY what I was looking for, and I wasn't even expecting it!!! Thank you for such an amazing visualization. Keep up the great work!
Fantastic video! The explanations are very good and the visualizations compliment the explanations perfectly. I really like the small scale illustrations of all the concepts. Kudos! Looking forward to seeing more on this channel.
That is INCREDIBLE high quality video! I have no idea how much time that took. I hope you'll find a method or tweak your style so that you don't need like 5 months pet video so that we can enjoy more of your content! Again, hat off for you! And please don't understand me wrong, your videos are literally perfect. I just don't want you to crunch.
6:33 That was such a good way of showing how the limited resolution could drastically affect the result. It's not a very complicated concept, but you just showed it so well
The production value of these is insane. The water splash at 4:04 was unexpected and fun, and the two robots representing brute force and analytical approaches were great.
The production quality of this video is just top notch man ! That's serious job to make such vulgarisation of complex algorithms so easy, great job ! If all educational supports could be so attractive we would all be genius......maybe :p Thank you !
The animation, sound, graphic, and overall presentation quality is literally insane. I'm so impressed and I don't even do anything related to this information, but man was I fully engaged. Instant sub lmao
The level of dedication and original graphics and visual communication is out of this world! GREAT video. You explain things well and your graphics help me fully comprehend the subject matter. Will be subscribing and following.
This is such an astoundingly well-made video. Clean, concise, understandable with exactly the needed amount of detail to understand the subject without drowning. And the production of the video itself is incredible too! I'll have to watch a second time just because I really want to focus on exactly what has been done mechanically to both animate the video as well as how it works together with the VO to help convey the message better.
I love this! The first method really helped me understand how I can make cool mountains straight in shaders, as someone who doesn't know how to code. I've been playing around with this kind of stuff for a while, but I'm so pumped to find an answer to how to go about it, when I wasn't even looking hahah Thanks for the video, it's very cool! Love the visuals you use, there's a lot of love that went into this
Wow incredible video!! I've never subscribed to a channel so fast. I'm staggered by amount of work you put into this explanation, and how easy it was to understand as a result! Looking forward to more of your work.
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!
What a phenomenal video. The simple but precise visuals turn what would normally be a headache to learn into a pleasure. If you keep this up I'm sure you'll be swimming in subscriptions in no time.
this was an instant sub from me, damn dude this is really really incredible... I can't believe you only have 62k subs... you will be at a million soon and beyond
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! I've always wondered how Minecraft generated multi-chunk structures, thought of one way they could do things (basically placing random points on a super scaled down world map) which actually just ended up a very convoluted implementation of cellular noise. Thanks for clarifying this!
I just saw your video in my inbox and I could swear your voice was familiar, till I noticed you also made the great video about Ray Tracing. Keep up the good work! You are entertaining and informative at the same time which makes listening to it much easier and more fun.
I've been fascinated with terrain generation for decades now, really cool to see visualizations of the various formulas in use. Channel name checks out.
I love this channel so much. It’s all the little things you do. Like how the bulky orange robot is used to symbolize the brute force method. And the lean elegant robot represents the lighter, but more complex approach.

6:33 That was such a good way of showing how the limited resolution could drastically affect the result. It's not a very complicated concept, but you just showed it so well
I love the sound effects. They really enhance the already stunning animations
I can't imagine how much work went into this video... the visualizations and animations are stunning, incredible job!
I don't think people realize how much detail and quality you have put into this video's animations.
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.
The production value of these is insane. The water splash at 4:04 was unexpected and fun, and the two robots representing brute force and analytical approaches were great.
The production quality of this video is just top notch man ! That's serious job to make such vulgarisation of complex algorithms so easy, great job !
If all educational supports could be so attractive we would all be genius......maybe :p
Thank you !
The animation, sound, graphic, and overall presentation quality is literally insane. I'm so impressed and I don't even do anything related to this information, but man was I fully engaged. Instant sub lmao
The level of dedication and original graphics and visual communication is out of this world! GREAT video. You explain things well and your graphics help me fully comprehend the subject matter. Will be subscribing and following.
This is such an astoundingly well-made video. Clean, concise, understandable with exactly the needed amount of detail to understand the subject without drowning. And the production of the video itself is incredible too! I'll have to watch a second time just because I really want to focus on exactly what has been done mechanically to both animate the video as well as how it works together with the VO to help convey the message better.
I love this! The first method really helped me understand how I can make cool mountains straight in shaders, as someone who doesn't know how to code. I've been playing around with this kind of stuff for a while, but I'm so pumped to find an answer to how to go about it, when I wasn't even looking hahah
Thanks for the video, it's very cool! Love the visuals you use, there's a lot of love that went into this
Wow incredible video!! I've never subscribed to a channel so fast. I'm staggered by amount of work you put into this explanation, and how easy it was to understand as a result! Looking forward to more of your work.
excellent explanations touching on complex subjects without getting too much in the weeds and excellent visually descriptive animations, subbed
Your visualizations are honestly almost as impressive as the content, well done!
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!
This was a GREAT watch.
Loved it. These two algorythms are very interesting
The visual style of yours is also simply beautiful
Your editing and visuals are absolute eye candy. Easiest subscribe of my life from 1 minute in.
Incredible work as always - it's remarkable to me that you continue to improve your production quality with every upload!
What a phenomenal video. The simple but precise visuals turn what would normally be a headache to learn into a pleasure. If you keep this up I'm sure you'll be swimming in subscriptions in no time.
God damn this video is underrated. So well explained and simple to understand. Really wish yt algos recommended this video more
There are some parts of this that I have no idea how you animated so smoothly. What a wizard 😵💫
I am amazed by all the visualizations. It's really insane how good your explanations and animations are
this was an instant sub from me, damn dude this is really really incredible... I can't believe you only have 62k subs... you will be at a million soon and beyond
Wow! I found a real treasure trove here! This channel deserves an extra diget to their subscriber count.
The educational quality and production value are exceptional!
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!
I've always wondered how Minecraft generated multi-chunk structures, thought of one way they could do things (basically placing random points on a super scaled down world map) which actually just ended up a very convoluted implementation of cellular noise. Thanks for clarifying this!
I'm shocked you don't have more subscribers. The production quality on this is immaculate
All of this and still 60k subs?! You are well underrated! Keep it up!
the amount of work put into these visuals is incredible
I just saw your video in my inbox and I could swear your voice was familiar, till I noticed you also made the great video about Ray Tracing. Keep up the good work! You are entertaining and informative at the same time which makes listening to it much easier and more fun.
I've been fascinated with terrain generation for decades now, really cool to see visualizations of the various formulas in use. Channel name checks out.
Im a bicycle mechanic why did i watch that whole video.
You are an excellent orator. And you do make things look pretty.
These graphics are on another level entirely. You're basically on another playing field in terms of quality. Incredible.
I love this channel so much. It’s all the little things you do. Like how the bulky orange robot is used to symbolize the brute force method. And the lean elegant robot represents the lighter, but more complex approach.
