Great video man, thanks for the shout out and glad you found the slides useful!

Amazing, thanks!

Best resource ever watch!!! Pure Gold and so straight forward. Thank You:)

Thank you! it's really helpful for understanding how GLSL top works.

Incredible! Thank you. I’m just learning Touchdesigner over the last few weeks. Tutorials like this are unbelievably helpful. I’ve been learning to use analog video equipment for well over a year, but there are very few tutorials, so it’s mostly experimentation with patching and trial and error.

thank you so much for all that effort and good documentation :)

Thanks, great tutorial, I learn a lot with it

Thanks for the wonderful tutorial!

really good tutorial, glsl is much lighter on gpu, very clear explanations.

Interesting how much curl noise resembles flocking behavior. Thanks for sharing.

Awesome tutorial, thanks!

Thanks a lot ! Awesome tutorial

Wow thank you Master Bruno !!! !!!

Many thanks, cool tut

Very nice tutorial. Thanks a lot

Amazing, thanks so much.

Thanks for useful glsl tricks Man lml.

Thank you so much!

many thanks this is amazing

Wow! Thank you!

존나 천재이십니다 존경합니다.

Thank you !!

thank you! my brain exploded a little :))

That’s great,thank you

Bella bruno!!!

You're amazing :)

Nice!

Thank you so much :)

Thanks 🙏

This is awesome! How would I go about replacing the cubes with an imported 3D object? I was thinking it would be cool to have fish swimming around and I found a cool object online.

Is there any chance you would be willing to share the file you ended up creating with this tutorial? It would really be helpful in my learning process. Thank you

thank you

Oh thank you soooooo much for such a wonderful tutorial!! :) I've learned a lot from it, but I still have some little questions Is the quantity of the boxes variable? and can there be more than one box emitters? I will be really appreciated to have your reply :)

Hi! i'm looking a way to limit the noise in a box, i was trying with some rgb math but i end up always getting wrong results you maybe got some advices?

Hi, this is really nice. I got to the Life part, but the cubes aren't resetting for me. Do you know what could be wrong? EDIT: I Used 32 bit RGB instead of RGBA

hey! fantastic tut! do you know a method to point to the center of the geo with my camera? I want to use your tech in a setup ultrawide for 3 projectors and I need the cam point to the center of the geo (e.g. when you home the camera, but constantly), lookAt doesn't work cause it doesn't recognize the center of the curl instanced noise. I need to point to the moving center of it, any suggestions? thank you!

Also, could you let me know how to add a cursor that attracts the curl noise and that glows red (lights up the background)?

First of all, thank you so much for this tutorial. Could you recommend ways to make it interactive with a Kinect? I saw your comment about using Optical Flow as an external force in the Vel. parameter in the GLSL shader, but how do you proceed with that? Is there an expression, or just declaring a uniform and then exchanging, per se, the uNoiseFactor? I am a student and I am really interested in the ways you would see this working out. Thanks in advance :) Hugs from Berlin

HI! Sorry but I'm writing with sublime text and when I paste the write glsl on it, it highlights in red the return word. That wont let me the script work. Do you know what it can be? The view syntax is in phyton mode. Thank you!!!

This is so cool tutorial but I am no idea about glsl, how can I learn glsl?

awesome！！！ 碉堡了

has anyone found a method outside of compute shaders for mac users by chance?

great

when attaching INFO dat - it's saying 'snoise' not found but i copied straight from that website.. what am I doing wrong?

Amazing and deep Thanks! I am an absolute beginer and went thru the whole tutorial step by step. I did acheive alot but my blocks are not flowing. They do move in waves but they are anchored to the center. What could be wrong? Can I send you my file?

Could I ask why my boxes don’t show cohesion ? Which parameter effects that?

Thank you so much for this. I am having an issue. For some reason, when I got to translate (r,g,b), nothing happens. I do not get what you get. It remains the horizontal rectangular block. Might you know why this is?

All good until I add Uniform float Utime; and add + Utime to the curlnoise and then everything stops. Sublime text is highlighting the return values. Really hope someone can help. I know this is a couple of years old. I haven't got a clue how to fix this.

Ciao! Tutorial e progetto veramente interessante! Ho solo un piccolo grande problema: come editor del "glsl1_compute" mi esce il blocco note di Win e non la finestra del video !!! Ti prego aiutamiii

Hello, this is so cool!! and I was following along fine until around 8:23 I get still have an error message after switching inputs to 2. The info DAT is saying this: Compute Shader Compile Results: Compute shader failed to compile with the following errors: ERROR: 0:18: error(#143) Undeclared identifier: nTDComputeOutputs ERROR: 0:18: error(#145) Left of "[" is not of type array, matrix, or vector: nTDComputeOutputs ERROR: 0:18: error(#202) No matching overloaded function found: imageStore ERROR: 0:21: error(#145) Left of "[" is not of type array, matrix, or vector: nTDComputeOutputs ERROR: 0:21: error(#202) No matching overloaded function found: imageStore ERROR: 0:25: error(#143) Undeclared identifier: color ERROR: 0:25: error(#202) No matching overloaded function found: TDOutputSwizzle ERROR: 0:25: error(#202) No matching overloaded function found: imageStore ERROR: error(#273) 8 compilation errors.

hi, is it possible to do it without glsl??

aww man says that I can't use a compute shader due to my gpu / os :( thanks though nice tutorial ! looks great

Thank you now I feel like Jimmy Neutron
