An introduction to Shader Art Coding

[@astral6749]

This is probably the best shader introduction in KZbin. It's very informative and it's also less than 30 minutes.

[@theherk]

I think this is one of the best instructional demonstrations I have ever seen, even beyond shaders.

[@hoang_minh_thanh]

Yes, Exactly, the best and most easy

[@fonzanedelungini]

But also very dense in information. If you truly want to understand what's going on, you have to do some research on your own.

[@astral6749]

​@@fonzanedelungini I didn't find it to be dense enough that it would require me to research on my own, but that's probably because I already have an idea as to how shaders work beforehand and the thinking that each individual pixel is its own process. Although I guess some of the functions that were used in this video might indeed make someone research it on their own to check the input parameters and the return values.

[@fonzanedelungini]

@@astral6749 Yes, I assume that for you this video is more of a summary of topics you've already spent time on than an introduction (which it is for me).

Wow. _WOW_ I'm blown away by this tutorial. I can't BELIEVE how well this is made, and how well you explained this subject. Even as a coder (as a hobby), shader coding has always been this gigantic terrifying unknowable thing, and half an hour later it feels so down to earth and doable. Here's a like, Here's a sub, here's a comment. More shader content _please_ !

[@campbellwinslow6986]

This is good to know others thought it was easy to follow, I was impressed, but very lost. Feels like I have a lot to learn about math/coding before this will make more sense to me.

[@Entropy67]

​@@campbellwinslow6986 take everything step by step, pause and do it yourself for each step, write notes in comments next to the thing you do (only move on once you understand and play around with it a little yourself) & don't merge the different parts together like he does. The videos 20 minutes but if you want to learn, you can easily spend a couple hours here. Its an amazing introduction. Don't be afraid of looking for resources and explanations on specific things you don't quite understand, some reaserching is gonna have to be done. You can definitely do it! Good luck

This tutorial will probably be the go-to tutorial to anyone who wants a quick hands on introduction to shader code. I am a programmer but i wanted to learn shader coding. I started learning through this tutorial, because the end result looked amazing. You introduce hard but useful concepts in a digestable manner, and it inspired me to stop and think more than once so I could grasp the unfamiliar math formulas and usages. Every step teached me something and allowed a checkpoint to let the concepts sink in. I am not surprised you did not release a lot of videos (2 atm), probably because you put so much effort into the presentation. I thank you for your efforts and for the wonderful tutorial - Condensing years of experience into very insightful 22 minutes.

God tier tutorial, absolutely unreal that this is the first video on your channel. This is where production quality and planning goes from being a comfort to being a legitimate pull for new people to the subject you’re covering. Mega cheers dude.

[@michaelwells6075]

No, I _did not_ notice the voice was AI, only that it was polished and articulate. This is one of the most fascinating YT videos I've watched. All the more so because I only _barely_ understood most of it-but *did* understand some of it. I'm 75 years old and have no experience with coding except for a thorough understanding of HTML, and a basic knowledge of JS and CSS. My original background and training are in the fine visual arts-i.e., predigital age, hands-on drawing, and painting with RW physical materials. That said, I've lived in the SF Bay Area for most of my adult life, occasionally rubbing shoulders with more technically-minded peers. Even so, I had little interest in computer technology until the mid-to-late 1990s when the internet came along. Before that, from the mid-1980s, although I had played around a little with visuals on what were then high-end systems belonging to friends who were more into emerging digital arts, I couldn't take them seriously. In those days, the only way to show anyone a digital image was to put it on a floppy disk and boot it up on someone's system. OR-Alternatively-take a 35mm film SLR photograph of the image on the highest resolution monitor available, then have the film processed and a print made from the film. - IOW, the way I saw it, there was no way to share the digital image produced with a mass audience _in the medium in which it had been created._ The internet changed all that as it was now possible to share digital images globally. Thus it was only then that I began to take digital imaging more seriously as an art form. It still remained more of a 'novelty' to me than something I regarded as a 'genuine' art. Along the way, I bought my first Apple/Mac system, began learning Adobe Illustrator and Photoshop, and discovered I had an aptitude for HTML (that was a big surprise). This was in the days when we wrote it by hand in MS Word, saving it in a .text format-then opening the .html in a browser. This led to a grasp of hexadecimal color values, and, later the addition of CSS and a sufficient sprinkling of JS to (at least) be able to modify code someone else had written-to adapt an JS slideshow on a web page, for example. The small publishing company I worked for at the time (1996-98) was sufficiently impressed with my skills that they wanted to send me up to Seattle for further training. But I _refused_ this generous offer because, bottom line, _I was a fine arts painter who only worked a job to support his art (large, up to 8x10 feet, very visceral-action based- abstract paintings) and did _*_NOT_*_ want my attention to become absorbed by the non-physical digital realm of emerging AR, etc._ The way I thought about it at the time was, "The ability to a) modify a digital image with infinite iterations, and b) infinitely distribute reproductions of those iterations as visual impressions, reduced any inherent value of that image to absolute *_ZERO._* " I still feel that way today! LOL But, putting all philosophical questions regarding the "inherent value" of _any_ image aside, this initial tutorial is fascinating! I didn't understand a lot of it (math skills stagnated at high school level Algebra II-Trig seemed beyond my comprehension and was of no interest whatever) but I understood enough. I already understood that pixels are like cells in a spreadsheet, and that image editing apps were performing mathematical operations on those cells -but now I FINALLY have a glimmer of understanding of what a _vector_ (as in vectors drawn in Illustrator) _*is*._ If I were 15 or even 25 and not 75 years old I'd probably be all over this, flinging my time and attention into fine-tuned digital image generation at the coding level! But as it is-I think I've had quite enough of this world already. I'll leave it to you youngsters to wander off into the virtual realm, and over the cliff of infinite iterations, of the emerging all-mighty (oxymoronic) AI. All I'll add is, "GOOD LUCK" - you're gonna need it!

Fr shaders are really important !

[@iheartbinary]

This tutorial was phenomenal. No setup required, everything is free and you can follow along in real time. I have not looked into your supplemental websites but seeing those tools for graphing and calculating the color palettes has really inspired me to look into this more. For a little history of myself, I have been fascinated with what I called "fractal art" as well as "visualizers" that came most music players at the time, but I had no idea you could replicate one with a few lines of code and half an hour of your time this easily! Thank you for inspiring me when I have grown bored of coding tutorials, game design feels too complex, and "app" design sounds so boring that it's basically just modern day web design in a container. But this? This is art, math, and science mixed into one easily accessible package!

[@hugopeters6627]

I have a bunch of experience making photorealistic pathtracing shaders but I've always lacked the reasoning for creative projects like these. This was super helpful thank you

[@perfectfutures]

I’ve never thought of shaders being used artistically like this, just for games. Fascinating and illuminating to see maths meet art like this- the results speak for themselves.

[@firefly618]

Thank you, this kind of shader art or math art tutorial is really cool! One small note: at 13:20 (and throughout the rest of the video) when you multiply the argument of sin() by 8 and divide the result by 8, you are multiplying and dividing different things. Multiplying the argument by 8 increases the frequency, which is what gives multiple rings. But dividing the result by 8 only has an effect on the amplitude of the resulting sine wave, which will oscillate between -0.125 and 0.125 instead of -1 and 1. So you might have just kept the oscillation between -1 and 1 and adjusted the argument to smoothstep(). Further on, at 15:05, in the same way you can remove the division by 8 and adjust the coefficient of the inverse function (0.16 instead of 0.02) The reasons for doing this would be 1. to avoid any confusion that the two 8 in sin(d*8.)/8. have any relation to each other (they don't, except for keeping the derivative close to ±1 when the sine wave crosses the x axis, which doesn't have much use in this case because you're inverting and scaling the resulting value anyways) and 2. to avoid division, which is still a costly operation in hardware, hence the fewer divisions you perform, the faster your code will be. Check out Quake III's famous Fast Inverse Square Root algorithm for an example of the effort programmers will do to avoid dividing numbers.

[@milanstevic8424]

This is completely true, I was also stumped with this explanation when it's completely obvious that the two factors are completely unrelated. sin returns -1..+1 by definition regardless of the frequency. However, I don't agree with the division remark that much, mainly because I've tested this idea. While it used to be the case that the division was significantly slower than multiplication (around 8-9 times), this is no longer the case. At least on a CPU the difference in performance is about 5-10%, however GPUs tend to be even more optimized in this regard because floating point math instructions are what they're made for. In other words Quake III is no longer relevant, however you are also conflating square roots and divisions which are completely unrelated things. This shader does a square root 9 times, has 3 natural exponentiations, 1 arbitrary power, and 2 divisions, per fragment! If you wanted to improve performance, first thing you would do would be to notice there are two length(uv0). Second because uv0 doesn't change inside the loop, both length(uv0) and exp(-length(uv0)) can be computed before entering the loop. This cuts square roots from 9 to 4, and exponentiations from 3 to 1. Finally there are ways to fudge the math slightly so that the compiler uses multiply-add instructions instead of having to multiply-then-add or divide-then-add. And after you convert the loop counter to integer (to let it unroll natively), this would improve the performance of this shader. Here I also got rid of one of the divisions by reciprocating the first expression. Here's what you end up with. (I've actually verified that this gives the same result.) Sadly it's crazy difficult to actually benchmark the difference, so I'll leave that to someone else. void mainImage( out vec4 fragColor, in vec2 fragCoord ) { vec2 uv = (fragCoord * 2.0 - iResolution.xy) / iResolution.y; vec3 finalColor = vec3(0.0); float luv0 = length(uv); float exl = exp(-luv0); for(int i = 0; i < 3; i++) { uv = fract(uv * 1.5) - 0.5; float d = length(uv) * exl; vec3 col = palette(luv0 + .4 * (float(i) + iTime)); d = abs(8. / sin(d * 8. + iTime)); d = pow(0.01 * d, 1.2); finalColor += col * d; } fragColor = vec4(finalColor, 1.0); }

I made it on Rust kzbin.info/www/bejne/hajdop6Be8mdj9E

[@fuzzy-02]

That algorithm was simply insane. Watched with Primgeagen

[@squarerootof2]

In the example d = sin(d*8. +iTime)/8. and then d= 0.02/d. How do you avoid d not blowing up when the sine cycles through 0 ? Or does d = sin(d*8. +iTime)/8. never return 0? Would not this crash?

[@milanstevic8424]

@@squarerootof2 Shaders do not crash from division by zero. (Nor does C# while we're at it, since floating points have a legal division by zero result, called NaN or "not-a-number".) Depending on the hardware, division by zero would either: a) return black, b) return NaN, or c) discard. NaN is hardware-specific and can be interpreted as an "error color", typically bright magenta (1,0,1) or again as black. Discard is more rare, but is present as an option in some GLs. In this case the pixel is simply skipped, though discard is expensive (because of branching) and problematic if the screen was not cleared first, and thus always discouraged by default.

What's with the AI voice?

[@beastworld8109]

He was trans and experienced dysphoria stop the hate

[@sebp400]

awesome! Best shader tutorial I ve seen so far for what I want to do. I like that you can get infinite variations just by adding a ''ceil'' , a ''floor'' or a ''sqrt'' in certain places.

[@mmettler42]

Software engineer that's always been intimidated by shaders. This was an amazing tutorial, thank you making it and demystifying them!!

[@HyperDev00]

Watched a lot of shader tutorials but this is the first time I've understood

[@konstantinrebrov675]

All in one tutorial, in the same format as Derek Banas, a comprehensive lecture touching upon all the main points!

I've been wanting to play with coding for art for some time, just didn't know where to start with the limited time I have free. This tutorial has that "winamp visuals plugin vibe" which is an aesthetic I actually what I want to play with, and eventually hook up to active datasets and an AI platform with input/output visualisation (think interactive visual exhibitions that react to what the audience are doing/the data tells it to do...). So, thanks to this very informative and intelligent video! At 17 minutes in I realised that I already have enough basic coding knowledge for a solid (2d) start; which is probably also testament as to how well and far coding visuals has come along. I hope you find another topic to cover soon, keep up this already high standard!

Just a tip I have noticed when trying to play with the code to understand it, if you subtract from finalColor it is easier to see the geometry created by the for loop and the line "uv = fract(uv * 1.5) - 0.5;" specifically the effect of 1.5 or other values in this line Also holy f this tutorial is the most immaculate thing Ive ever seen

350K views on a shader video! I can't speak for everyone but a promise to watch any shader video you make. Great video!

[@valentindumitru9492]

Your explaination of f(x, y) => f(r, g, b) made so much sense, thanks for that

[@erikjohnson9112]

"The Art of Code" is another good channel on the topic. There is plenty to learn so I am just highlighting another source to learn from (in addition, not instead of). Shaders can do some incredible things, and Shadertoy is so easily accessible, there is no reason not to try these (even if you just tweak other peoples' work).

[@neonmarblerust]

Very cool. Lots of good stuff in those showcased shaders

[@ramanmono]

Now we can make winamp visualizations again. Great tutorial. Very insightful.

[@MacShrike]

I have been playing with AGAL with moderate success. This video is extremely useful and insightful. Thank you very much.

[@noah_bmp]

I did learn about shaders during my engineer courses, but it was only a small part of those courses and it focused only about the technical behaviour and not showing any graphical results, seeing this, with a graphical output gives a really good view and makes it crystal clear to learn, thank you !

[@rolandomotta6354]

This video cleared up many doubts I had about how to approach the process of programming shaders.

[@Fidel_Villeneuve]

I've been looking for something exactly like this for 2 years. I have almost no experience in coding, but thanks to your video, will give it a go!

[@odonata9766]

This is what ai should be used for, a tool to make communication easier for people who have something to say or teach but maybe not the resources or skills to do it with their own voice. Great video, will be going back to it a lot.

[@user-bb3rr2dq7s]

Great tutorial. I was mind blown at the use of fractals and combining that with well known math functions to produce very interesting results quickly. The palette function also seems incredible useful for creating color compositions to anyone's liking!

[@luckyWabbit75]

An exceptional intro to shader programming. It has really clarified my thinking about frag shaders. Please keep up the awesome work!

[@sossym4t339]

Dammi boy. It's just beautiful, and you presented it flawlessly! U just made a single video and got thousand of subs! Congrats

[@KnightMirkoYo]

Wow, this was a perfect introductory video. It sparks curiosity and confidence, and starting our own experiments doesn't seem daunting at all. Absolutely perfect video.
