"I researched not 3, but 2 techniques..."
idk how i found this channel but its so entertaining and funny and informative
when? where?
@@tcharlesleonardo1681 2:39
I got to that and it became reason I subbed lol
@@tcharlesleonardo1681 2:39
A whole not 3 techniques. Impeccable.
I was like: Did I just hear that right?
Would u have clicked if they were whole lot 2?
what's this mean?face-turquoise-covering-eyes
Didn’t get what that mean..
@@tigranrostomyan9231 @kenshin1238 at the start he said "i researched not 3 but 2 techniques" which sounds odd
I love when I'm just about to reach a summit after climbing for days, and a talking dog pops out of snow, teleports me and my fellow platonic solids to a shapeless void and explains mountain generation algorithms to us!
that was SO FUNNY. i loved it
i misread this as "and a talking dog poops out of nowhere"
@@dialog_boxI read it as a talking poop dogs out of nowhere
After the 17th time you kinda expect it annoyedly, but get a little disappointed when it doesn't happen.
"Not three, but two" got me.
So tired of these copy paste comments
@@yodaman8015 good thing I actually typed it out since I was being genuine....
@@ThatRobHuman your comment is stale and used over and over is what I am saying.
@@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.
@@yodaman8015 thanks for sharing your opinion - the neg could've stayed in your drafts.
I love how you use a bulky robot for the brutal force method and a slim robot for the nerd method
Not just that, his bulky robot moves discretely (in small hard steps) and the nerd robot moves continuously (fluid motion).
@@Arnaz87Never noticed that. Wow!

@@Arnaz87 Nice catch

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
hello random youtuber with 1.25m subs
Greatness recognizes greatness.
hello random youtuber with 1.25m subs
Thanks! It really means a lot to hear that from you, I'm a big fan of what you make.
Can not wait for either of you two to make another video on the topic
White dog talking to 3 shapes about mountain generation is something I never knew I needed to watch until now
I've never been so quickly hooked on a video about noise algorithms
Simply amazing how high quality RUclips edutainment have become.
Cool plain explains
Agreed. That's why i keep a public list of the high-quality channels out there.
actually, these were mountain explanations, not plain explanations
@@OrangeC7 not a plain explanation, but certainly an explanation on how to manipulate planes :^)
@@SplarkszterMay I see your public list of high quality channels?
@@neatsketchi also need to know. Just commenting so i get notifications
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"
Thanks for the recommendation!
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.
thats one hell of an opener, and i absolutely love it
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
Yeah, it's like 3b1b but the math and science is accurate.
that "not 3, but 2" is a golden defying expectations line.
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!
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.
The production quality on this is insane, I can't believe I am watching this for free. Instantly subscribed
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).
@@DreadKyller good ideas, i was loading an 8 bit image anyways so thats why I only mentioned 256, i should have made it more general
Thinking Perlin looks ugly is exactly why I'm here as well. This is a great video.
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.
@@user-pj5oe6rb4i you are right, its great for making procedural textures, but im some contexts like world gen it really shows how ugly it is.
1:35 That sound design… it’s so subtle, but with good headphones, it really adds to the quality of the video!
This is exorbitating quality from a RUclips 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!
inigo quilez is an absolute legend, everywhere i go i keep being led back to his work
Is Indigo Q-Lez how it’s pronounced.
You have to watch the Video 3 times, then RUclips allows you to see algorithm #3, using Simplex Noise, at the end - it's brilliant!
Thank you ^^
Insanely high production value, very snappy, and good writing! Genuinely surprised your channel isnt bigger, i feel like im buying in before it skyrockets
Extraordinarily well done animations and precise explanations. Your channel is so underrated!
I just stumbled onto this channel and the quality is amazing! Great job!
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. 👍
Computer science video pls?
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!
Incredible work as always - it's remarkable to me that you continue to improve your production quality with every upload!
Dude, you make the math so approachable with these amazing visualizations! This is seriously top notch educational content.
I love the editing and you explained the concepts really well. Hope to see more content of this type from you!!
The amount of effort and detail you put into this video is admirable, thank you!
You got me wanting to experiment with Perlin noise and mountains now 😁
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 amount of work put into these visuals is incredible
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.
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 : )
Im so hyped to see someone finally do better than the "it looks pretty good" of perlin noise
So true
I can't imagine how much work went into this video... the visualizations and animations are stunning, incredible job!
It's always so cool to see information rich videos like this with an impeccable visualisation, that is not only clear but beautiful to look at!
It must takes so much more time but it's so much better as a viewer, thanks for taking this time!
The erosion lookalike technique is really interesting I can't wait to try that!
I love the sound effects. They really enhance the already stunning animations
Your videos are by far some of the best on RUclips. You deserve so much more recognition than you get. I love your videos so much
Im so glad youtube recommended this video to me! I’ll be going through your other videos now, this one was so good!
excellent explanations touching on complex subjects without getting too much in the weeds and excellent visually descriptive animations, subbed
Awesome. Thanks for sharing your hard work. Stunning visuals!
This is incredible man! Both the content, and the visuals!
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!
Absolutely brilliant video! So well illustrated and beautifully explained.
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.
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
This may possibly be the best video I've ever seen, holy cow! Amazing work!! :D
Stunning visuals, great explanations and an interesting topic. Thanks for sharing
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.
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
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!
The animation's on this are just mind-blowing. Awesome video!
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.
Keep up the godd work. The Quality of your videos is just unrivaled.
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!
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.
Some of the best visuals I've ever seen in an educational video, great work!
Just found this channel. Instantly subscribed. Phenomenal explanations and incredible effort. Thank you!
I wasn't expecting a video this high effort about random noise, but I'm pleasantly surprised. Subscribed. ❤
The quality on this is crazy. Subscribing after one vid because you deserve it
One of the best and most curated video I’ve seen so far
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
You don't even need to be interested in the topic to watch this video, you can watch it for the insanely talented made visuals
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 is a genuinely brilliant video. The production value is great, but the explanations are excellent.
You did a GREAT job on the presentation, which really made the topic even more interesting. Excellent!
This video is absolutely fantastic! Hope this gets a lot more attention man!
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.
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.
This may be the most pleasantly animated video I've watched in a very long time. Incredibly good animation, sir.
This video is such great quality, you did such a great job! 🙂
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!
The animations are incredible and help a ton understanding these concepts
Wow. Incredibly high quality video and very full of information. I hope to see many more in the future! Keep it up!
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.
Literally my new favorite channel!
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!
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 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!
Really good video man. The animations are, as always, so cool and clever. Hell of a lot of work behind this. Keep it going! :)
This is 3B1B levels of production quality and explanation. Fantastic work!
Absolutely excellent explaination and visuals, loving it
I'm so impressed that you researched 2 techniques instead of 3. Incredible!
Man the visual alegories with the vfx here are soo good!!
Hello Josh! You have an incredible channel. I will be using these techniques in my projects, thank you so much for your work.
This is so cool! Thanks for the high-quality content!
Intriguing subject and extravagant visualizations. Great work!
This is an unreasonably well polished video.
All of this and still 60k subs?! You are well underrated! Keep it up!
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!
This is probably the most creative technical explanation I've ever watched.
Very well dictated and shown intuitively. Incredible work
Great content Josh, please keep making high quality content about the math of game development like this and ray tracing.
I'm shocked you don't have more subscribers. The production quality on this is immaculate
This is gorgeous, and very informative.
Instant subscribe for that awesome production value! 🔥 I was working on an algorithm a while ago that used simple texture reads to generate landscapes. You feed it tiling displacement maps and it repeats them at various scales to create realistic terrain. Worked pretty well! It was fast enough to displace an 8km x 8km terrain in realtime using Nanite in UE5.
Absolutely amazing presentation, I feel like I have a good enough overview to build either of these in pretty much any language I want, plus know how to dig deeper if needed. Quite possibly the best technical explanation I've ever seen in software.
this is beautiful, it scratches my brain the right way
