The ONE Texture Every Game NEEDS

I feel like they should use videos like this in high schools when students ask "when will mathematics ever be useful in real life?", because so many kids play video games. They can see how a function becomes a graph, and how any points on the graph can represent things like patterns, motion, time, sound, and that the sounds can be sampled for music. There is a lot of experimentation like "If we do this to the graph then this happens", and people who are learning need to be encouraged to experiment to make the process of learning more enjoyable.

The production value, the explanation, the amount of valuable information... astounding. Your videos will help many developers for years to come. Thank you.

Skill level = master. You remind me of a senior developer I worked with once, who had reahed a level of knowledge in which he really could create art with code. It's a beautiful thing.

The realization that I've been taking noise for granted for years now, even though it's in every single project I do. Thank you for teaching me something I didn't know I needed to know.

Noise is also useful in sound design, with the right filters layered on you can get all kinds of ambient backgrounds, machine sounds, sci-fi devices, percussive effects, and so on.

Wow. At first I thought this video would be sort of a review for me. But once we've got domain warping planet weather systems I realized holy holy this overview is ... beyond an overview! Amazing techniques at the end. Imagination is the limit!

A neat effect I've been using for my terrain gen, that could be useful for all kinds of texture synthesis, is using one noise field to distort another noise field. This creates a combined noise field that (can be) globally isotropic, but locally anisotropic. For terrain gen, it helps mimic "long" features, like terrain buckling & folding. By tuning the dominant frequency of the distorting noise, you can tune how quickly the local directionality of anisotropic features varies.

Noise can also be used to procedurally generate levels on roguelikes and Minecraft/Terraria like games. It's no joke how useful it is. I made some Unity tool scripts to generate noise textures easy and quickly from inside the editor because I use them everywhere on my visuals. They're on my skybox for clouds and stars, on my fog, flames, smoke, water, swaying vegetation, literally everywhere.

This sort of breakdown on core concepts is lovely to see, often as a tech artist I inherit a bunch of techniques without a grounding in how they were generated in the first place. Production quality is fantastic too!

Honestly am starting to be impressed by the new (?) youtube recommendation system, this channel is a hidden gem and am so glad it popped up in my Home videos!

Straight to the point, no fluff. 👍 I still have a weak spot for everything involving noise/procedural textures. Shout-out to Steven Worley; it was a pleasure working with you back in the 90s.

That was awesome. Subscribed!. Love how you just talk in a voice like it’s no big deal meanwhile entire worlds are begging created.

At 4:42 you perfectly described how mixing signals results in phase shifting.

Let's welcome for today's lecture, and make some noise for SimonDev! (sorry not sorry, had to do it :D )

Didn‘t expect to see an explanation about noise containing so many effects and uses. I‘ve learned those effects by experimenting with shadernodes in Blender, but never thought about them in a more mathematical way. Amazing video!

I legitimately just made value noise based off the notions in the lerp video a week or so ago. You can get some interesting patterns with it if you jam in some crazy functions. I even made an eye model with it a few days ago, because Halloween is coming up. Great videos, they've been a helpful resource.

I'm using Perlin noise in these days, and this video came up, amazing. Really well made, congrats!

One of my favorite videos of yours. Very entertaining and watchable but still technical and informative.

Gawd dayum the way you explain complex topics this simply gets me every time. And the visualisations look neat. This channel is heaven

Thank you SO much for the 'domain warping' keyword. So Wild that in this world magic search terms are so important. Thanks!

This video is truly incredible. Fantastic job, Simon!

If I am not mistaken, this is the best video ever published.

Wow, so many high quality Infos in such a short video. Amazing

God damn what a pleasure it was to watch that! Keep up the good work dude, you’re 1 in a billion

This is so beautiful, simple and motivating, I just wanna start playing around with it right now. Thank you!

This video me realize the similarities between the Fourier series and noise generation. I already knew both, but since I studied physics in college I had a better understanding of the Fourier series, and I definitely got an Aha! moment at 4:40. Definitely helps with my understanding of using noise.

This is the best explanation of gradient noise I've ever seen

Man, this is some top tier RU-vid content ! Thank you so much for these great videos !

Incredible video. Full of information and still explained in a simple way.

In your previous video, I asked you to create another math video and you did. I officially love you forever. Keep up the good work!

Okaaaaay - big flex here. Super nice video. You will regret not having bookmarked this for later reference.

I will save this video cause watching it once is not enough, thanks.

Great edutainment. I really like that you visualized so many variants!

I really enjoy your videos, keep em coming!

Woot! Friday and another solid video.

I've been using these noises for so many years and still i learnt new things today Thanks a lot.

Well done video! Thanks for the work you put into these!

Literally 30 seconds in and I'm genuinely impressed by how insightful this video is.

Amazing production quality

Fascinating! I also love how this turned into a close-up view of a biblically accurate cherubim

Great video, the explanations and graphics are fantastic. It's spooky, I literally just made a video on making 4D terrain using Perlin Noise on my channel! It's amazing how versatile some simple noise is.

The content here is absolutely educational, thanks for the noise!

This was just beautiful. Well done Simon

PRICELESS CONTENT. HIGHLY APPRECIATED. Not sorry for the caps. Again, thank you for this video!

One of the best devlog-style videos since Sebastian Lague, and presented with such a smooth style!

Holy poop, what a great video. Thank you for this! So much value in just 9 minutes. Subbed!

This is really cool, thanks for explaining stuff like this. Although the triptophobia eyes at the end sorta got me! Still very cool, subbed :]

Thanks for the explanationabout noise, this was really useful.

feel proud for understanding everything in the video

Very cool and informative. I loved this video!

Wow, such an amazing way of teaching, congrats, what an amazing video, i loved it a lot.

this isn't exactly what I thought this video would be about but I found it immensly interesting regardless.

Beautiful video and the explanation was so well done!

I'm a big fan of noise functions (from a theoretical perspective, actual practice is a bit lacking 😄) so I loved this video, and wow what awesome visualizations! Great work

Wow. So well packed info! Great explanation.

Awesome as always

This is a really great introduction to procedural generation! I must ask, what software do you use for your 2D visualizations? Like with either the graphs, or the grids you used to show different types of noise. Also XD How did you do the star pattern? Was the star position's in 3d space? If it was 2d, and the stars were placed in a grid, how did you manage to pack all the tiny stars close to eachother if there was 1 star per grid tile? Well, I guess you just added more! haha. I've been wanting to make a video for a while talking about how some assembly math instructions are slower than others, and present a "high level" view of it for people who might never touch assembly.

You are a master. This is so wonderful! Would love to see some videos with some pseudo code included. Hopefully your other videos will contain just that! Cheers!

really appreciate the work, thanks!

Hi SimonDev, this might sound unlikely, but I'm 42 and I've wanted to get into visual or audio related programming since forever. Everything I've watched or read seemed either too abstract (hard to see a use-case) or just uninteresting (severe ADHD makes it impossible engage if it isn't exciting, even when medicated), but this video opened it all up for me, and I surprised myself by how many use-cases I've dreamed up since watching it yesterday. It's much like what learning practical music theory concepts does for my desire to compose and perform music

What started so simply ended up looking like a nightmare. Bravo on making pseudo-random really scary.

an excellent video. really awesome!

Thanks! I have been wanting to know more about how noise works for some time.

Amazing video!

I thought this was going to be about audio noise, which was ironic because the audio quality was really bad - lot's of popping and stuff. However the content was good enough to keep me watching, so good job!

I'm utterly hopeless at anything related to maths and programming, but I'm (unfortunately?) super interested in how it's used. You explain all these concepts in a really approachable way that almost makes me think I could use them, myself. I'm a graphic designer/UI artist and I use these functions in my design tools, but the program calculates it all for me. It's nice to know more about how they work!

Simply, Thank you

This is extremely interesting stuff. I hope to make games some day and will be coming back to your channel for sure.

It's the same in the audio world... brown noise, white noise, ect ect its huge for adding harmonic content

you're a legend simon

Brilliant use of noise to create amazing effects!

I don't code, but it's so cool to watch these things. Keep it up.

So nice that we starred with a great noise generation tutorial and ended with a some celular-shaped eyes nightmare fuel

Great video!

Very nice video. I remember an old game made use of noise for it's textures so it would fit in a floppy. Doing so had the effect that it used alot of memory but it was indeed cool.

I love videos like these.

I used noise to generate detail bump maps for extremely fine grainy details for when players get up close to a 3d model. I think Minecraft also used noise for terrain generation at one point, not sure how it's handled now though.

Amazing video.

holy moly this is hella cool! Could probably use it sometime but idk for what

Awsome video!

I love this channel so much ❤️

Nice video! Really hope you can made some video about webgl texture.

These videos are like GameDev forums vomited all they know in bite sized technical chunks, cannot get enough.

Such an amazing video, but the preview almost scared me away from watching it!

Cool and interesting. I’ve subscribed.

I've always loved procedural terrain. So much fun to be had with a bit of randomness.

Nice one!

This video is Great! tnks.

Again, my computer graphics course thanks you Simon!

New title - ‘Bob from Bobs Burgers Explains VFX Noise’

When I started messing around with Photoshop as a kid, I was always perplexed at why there was a "Render Clouds" function. Like, what a weirdly specific thing to render? But fast forward a couple decades and as a game dev I totally get it now. I use noise in EVERYTHING in my games. Fun fact: Photoshop uses Perlin noise to render clouds, and it's tileable.

Great video as always, what are you using to make the 2d viz?

Very interesting and helpful. Funnily enough today I was thinking " thank goodness for randomness", because if not for that, in games, simulation, or actual life itself, outcomes would be exactly as determined by the underlying "rules", i.e. banal, predictable and ultimately totally boring. Somehow, randomness gives variation, meaning and potential / opportunity

Pleeeeaase add an in video flicker warning, I’m usually not affected by most flicker but this even got me almost immediately. I see you pinned a comment but unfortunately I didn’t see that until afterward since I’m watching on a tv. Love your videos, looking forward to what you make next Edited to add: Such an awesome video! I’ve rewatched a couple times and I think one of the things I love most about your videos is you tend to manage to neither oversimplify nor overcomplicate each part of the concepts/techniques you focus on, and end up with something that is straightforwardly understandable yet builds into complex and cool things in a way that leaves me feeling fascinated and eager to learn more :) Thanks for the acknowledgment, and I hope you get to have as much fun making these as we get to have watching !

presentation level: god

Hi Bob from Bob's Burger's, very good explanation of pseudo-randomness!

Absurd good video!
