Thanks! ❤️ This one came straight from the heart. It's how I often feel these days. On one level its clear that humanity as we know it is about to expire, which induces panic with no clear direction to turn to. On another, there is this calm place inside of me that isn't disturbed in the least by all the outside turmoil.

Great! :-) Let me expand on those two: i is the counter variable of the "Particles" buffer. It is a three dimensional vector array of integers that is increased per particle, but we use only the first dimension, which is accessed with .x (the others would be .y and .z). We could also write i[0] to access it, if you are more familiar with that notation for arrays. So with 1 million particles for each of which our code is repeated per frame (!), i.x will be 0 for the first particle, 1 for the second, 2 for the third and so on up to 999999, so that we know which one we are working on. hash11 is defined in the #include file hash-functions.hlsl that you can find in your installation in Resources/lib/shared. "hash" is often used as a name for pseudo-random number generators, "11" in this library means, that it receives one input and delivers one output. You can also think of it as hash11(seed). So it returns a different pseudo-random float value between 0 and 1 for every input value, every particle in this case. Pseudo-random means, that it will return the same random number for the same input value, so that the same particle number i.x will always yield the same random value. This is important if you think of a stream of particles: The one that is faster than the others should always be faster on every frame, the slow one should be slow on every frame, so that we get a consistent result (real random numbers are hardly useful in animation actually). You may be more familiar with something like rnd(seed) from other languages.

@@thomashelzle so kind,got it,i need time to get into the new world,thx again

You are very welcome! 🙏 And yes, give it time to wrap your head around. It took me half a year to get comfortable with it and it will probably take me much longer before I REALLY grok it all... ;-) Learning is the best thing in live - I'm 59 and just starting with this new adventure... ❤️😎

The rotational part yes, although I also use a custom noise force here that is not part of the tutorial. I'm uploading the tutorial right now so stay tuned ;-)

The tutorial is live now! ruclips.net/video/j95VZXGAbwE/видео.html

....and a mighty voice says: "Was guggst du"?

Not sure yet, I'm still improving the force... ;-)

@@thomashelzle The video is perfect as it is. And thank you for your time and effort. Cheer up!

The tutorial is mostly technical about how to write shaders and create operators BTW., I don't cover this animation or the others where I use the force.

The tutorial is live now: ruclips.net/video/j95VZXGAbwE/видео.html Enjoy!

Yeah, really beautiful voice there! :-) It is mostly four layers of this at different speeds and pitches: d1 $ repeatCycles 2 $ n (scale "harmonicMinor" $ struct "t(5,7,<0 4 3 1 2>)" $ (irand 8)) |+ n "a4" # sound "loopMIDI" # midichan 0 #amp (range 0.7 1 perlin) The numbers samples use: d9 $ slow 4 $ n "[0 [1 2]]" # sound "numbers" # n (irand 10) # amp 1 # pan (rand * 0.75) The interesting thing for me was the repeatCycles to make the randomness into repeating patterns. I wrote similar things in the past in Processing, but that was way more involved. I send the Midi to Bitwig via loopMidi and into the "Noire" Piano.

Thanks! 😄 Love it too! :-)

@@thomashelzle Indeed! :^)

As long as humans don't understand that all we do is informed and motivated by trauma, not "free will", or "consciousness" or "intelligence", I see little hope of getting out of the circles of destruction. If we manage to transcend trauma, we may become wise after all...

👍Yeah, Tooll3 is great in that it encourages you to go further and experiment with those basic ingredients. I hadn't heard of Lenia but recently I stumbled over particle-life.com/ which I found pretty amazing...

@@thomashelzle There's a lot of cool artificial life (ALife) models out there, including ones that are supposedly very open-ended and can continue to show evolution. Recently I've been following along with the T2 Tile Project, and though a lot of it's over my head, it's still neat to think about.

@@PunmasterSTP Yeah, those models are really lovely, but I'm not fully there yet either ;-)

👍Yeah, that's how life is supposed to be, if you let your curiosity take the lead... ;-)

Thanks a lot! :-)

I don't know the movie so wouldn't know... ;-)

Good question, next question

It's a reaction-diffusion system in Tooll3 - a very simple form of this: www.karlsims.com/rd.html, using a blur and a sharpen filter in a loop :-)

Thank you! 😊🙏🙏🙏🙏

When you apply blur and sharpen filters in combination on a starting structure (can be anything, here it's my companies name ;-) ) in a feedback-loop, a structure called "Reaction-Diffusion" emerges. It is very common in nature, on many fish (think little Nemo), zebras, even tigers but also happens in chemistry when mixing two or more ingredients that do not mix but interact. Organic, even-spaced stripes that are interconnected in very interesting ways, depending on the substances or settings in this case. From the white part of that, I emit particles that are moved from their starting points on the texture with a fractal noise force and change colour over time. Does that give you an idea?

yes, it does! it can all be described mathematically it seems. find it quite fascinating how the same patterns come up in different enviroments and can be described as a single event. the "blur and sharpen filters" helped me a lot on intuitively understanding how it works. thanks for your explanation, amazing visuals!

Yeah - using blur and sharpen filters is the "naive" or simple way and not as flexible as if one implements the full formula of Gray-Scott Reaction-Diffusion or the other models. That is deeper and allows for more variety in the resulting structures. But it's quite nice already and with some modulation of the parameters, can lead to beautiful results. I implemented a more complex RD kernel in SideFX Houdini some years ago: ruclips.net/video/ZxTHcbxAqq8/видео.html ruclips.net/video/3mtp7iXE1WA/видео.html I just totally love those patterns :-) I may implement one in Tooll3 one day too in HLSL.

Hahaha - yeah, lots of possible associations there... ;-) Cheers!

Thanks!

Thanks! One of my favorites! :-)

Thank you! :-)

Thank you! Cheers!

Thanks! 🙏 Yeah, I first saw it as a blooming flower, then as a space nebula I'm flying through backwards while rotating but I can also totally see a morphing eye! 👍 I love those polymorphic things 🤩

It's a particle animation in Tooll3 that is driven by the generative soundtrack I created in Bitwig Studio. A custom noise force with symmetry allows for the mirrored look. An also customised depth of field effect does the blurring/bokeh. Otherwise it's mostly fiddling with the parameters until it feels right... ;-)

Thank you! Trying out new things and sounds... :-)

🙏 Ha - thanks a lot! Love it too :-)

Thanks! :-)

Yeah, somehow the comments seem to be remixed too ;-) Nice work!

Thank you! :-)

4 million. Running in realtime on my Laptop with a GeForce 3070. This isn't a screencapture though, it's rendered out as a video and due to encoding takes around ~20 minutes on the same laptop in 4k with 60fps for the 18,000 frames of the full version: ruclips.net/video/_DtroPU32mQ/видео.html

Thank you so much! :-)

Yeah, but I love the B&W things a lot as well :-)

Great! :-)

@@thomashelzle would love to remix it

Go ahead and show me what you come up with :-)

@@thomashelzle ruclips.net/video/HnaS_hxmXqw/видео.html

Ha! Quite the kaleidoscopic experience - Nice! :-)

Yeah, the border between chaos and order is where it's at for me :-)

@@thomashelzle i love playing with generative chaos on vcvrack but not musically

VCVrack is actually in the track, but only as an effect this time around :-) I'm using a kick drum from Atlas and the percussion is actually AAS String Studio played by the Pigments step sequencer on one track and the Spiral Reaktor ensemble on another. The percussion is stretched extremely with Paul Stretch and then going through VCVrack and the fantastic Cytomic CF100 filter for the ambient wooshing sound. I use that filter a lot. Valhalla Vintage Verb for reverb + a bit of Valhalla Delay. But some of my animations are purely VCVrack for the sound.

@@thomashelzle awesome .

It is all created mathematically. 8 million tiny particles are objected to a "noise" force that influences their movement. That noise is a pseudo-fractal - the same noise repeated at different scales, in this case 9 times. This creates the complexity. I programmed into this force that it is reflected along the x axis. So the force is symmetrical, but not the particles, which makes it much more natural. And yeah, sinking into these and let the mind wander is what I love to do as well... :-)

Ha - great :-)

Hahahah - yeah, that makes it so alive and organic. I could start with totally symmetrical particles to make it "perfect", but that would be pretty boring IMO.

I don't know portal so that's a coincidence ;-) Great you like it - experimenting with many styles at the moment and building my "arsenal" of toolls - and just staying in the flow...

omg you're right it does sound a little bit like a portal ost

Thanks a lot - it's what I love... :-)

Hehehe - thanks!

Many thanks!

Yes, that is the idea with all these animations. Living paintings ;-) Not shouting for attention but something to be with, everchanging, alive...

Thanks! As for a one hour or longer version: That never occured to me. The realtime version in Tooll3 is in itself endless, so in theory it would be possible to create a longer video. Hm... Let me think about this :-)

Great you like it! Yeah, it's quite magical indeed. The next animation is already in the works... :-)

Glad you like it!
