- Hey, It's been four months already 👀
I finally found some time and courage to make another tut. Hope you gonna like it, It's a basic GLSL particle setup with compute shaders, I want to do more videos about particles in Touchdesigner, so this one is a kinda basic setup that I'm gonna reference a lot in future vids.
Hope you're doing well

exactly what I was looking for to learn compute shaders techniques in Touchdesigner. And using constant TOP as buffers.. nice. My GPU doesn't think so though. I have to turn off ''clear output'' to make the data feed back but can't connect the instancing since it makes my whole crappy laptop freeze. Time for a good graphics card!
short and nice as always!
So great, thanks!! Exactly what I want to learn right now :)
I like your tutorial a lot !!
amazing, thank ya
Awesome, I am excited to learn this program! ^__^
nice!
Juste to say that english is not my primary language and I'm a beguiner whit td.. so I followed this tutorial at 0,75 speed and yep, I felt like morty listen to a rick's td tut haha 7:56
Btw thanks for it, it realy help !
thanks for the great videos, im getting a warning/error following along on the first render: 'a mat is using texture coordinates, but the sop being used with it doesn't have UV attributes'. Should i just use the texture SOP? Anyone run into this?
Thank you. 감사합니다.
you are awesome! so great and short but super clear tutorial!

Hello, thank you for your tutorial. I don't know why. This component is not displayed at all. It is black
Great tutorial but please how can i have this interact with a kinect
Can you please share the source of the opening rendering (the noisy purplish system)? I need something just like this for an upcoming project :)
Hello, thank you for your tutorial. I don't know why. This component is not displayed at all. It is black
Thank you for this tutorial :) I have a question, how do I duplicate those OPs? Is it the same as copy paste? I would rather use the same as you not to make any confusion. I have some complications and it seems velocity doesn't affect the pos...and I was following your instruction step by step except Duplicating I used Copy/Paste and I' m wondering if that was the mistake. Thank you for your answers :)
I finally mannaged to finish it :)
@@elizazryvombrozy Any chance you remember what your problem was? I'm having a very similar problem with velocity.
nvm I got it. My problem was the line "pos += vel * step", I had "pos += f * step"
Really great tutorial! Do you mind if I share an example .toe file that runs on Mac? I just translated the code to a pixel shader.
Thanks! Sure, go for it, the only thing I'd ask for is if you could credit my video :)
@@noonesimg oh sweet, I just meant as a comment on this video
@@blankensmithing hehe, oh, okay then, if you post a link in another comment, I'll pin it for the generations to come :)
@@noonesimg hmm for some reason youtube won't let me post a comment with a google drive download link in it. It keeps taking down my comment
@@blankensmithing im trying to use particles but it never works.
could you plz send me the code that works on Mac?
Is this something that can be done without compute shaders? (ie: on Mac). I know you said compute shaders are not supported on Mac, but I am looking for an alternative. Thank you for this video!
In this particular case you can probably get away with with using regular fragment shaders, but you have to make two glsl TOPs: one for updating velocity, and another for integrating velocity to position and lifespan count. As far as I know fragment shader allow only one output buffer.
@@noonesimg thank you this helped a lot!
um, can i ask what is it with reoder, because i don't understand about that. i try it, great video btw.
Reorder TOP let's u mix channel, i.e. use one's image red as a blue channel for another image, etc. Here I use alpha channel as a life value, so the noise TOP offset will represent time in seconds until a particle gets reset. And the reorder TOP is used to output that value on the alpha channel.
@@noonesimg thank you so much for the reply, but I haven't fix it tho 😭, it keep pulse in and out, but when I Bypass the reorder, it create really beautiful wave tho.
What's the editor that you use with TD?
It's VS Code
@@noonesimg thanks
Hey, I tried the whole thing step by step but am failing at the force part around 4:30. After entering the lines in the Editor nothing happens; all the Windows remain black and the noise remains static. Anybody gotvany ideas what the problem is? Tried everything twice and am Sure that I did it the exact same way..
Hi! Have you clicked on "Save" on your editor after writing the code? Many editors don't have automatic changes
Same issue. Although everything is same as in the video, node names, adjustments, script all tripple checked and yes svaed the script, I am still getting an error in the glsl script.
When I drag the Ramp to the Color OP, an error appears. Why?
Error: All OPs must generate the same number of instances (have the same lenght)
Because you have to put the same resolution as the pos and the vel, the standard resolution of the Ramp is 256x256
@@paolabelviso7465 Thank you.
how can I do this on a mac?
Sorry, I don't think it's possible. Compute shaders require OpenGL 4.3+, and MacOS supports only 4.1
@@noonesimg :(
Just posted an example in the comments. Hope it helps :)
lol @ FORCE
whats basic about this??? jajaja awesome tut tho, im just starting on this so... @_@
"basic". ha
Do you call it basic? Misinformative..
Too fast for someone whose native language is not English. Shame.
No explanation, we don't understand anything about what we're doing.
I think that a tutorial should also be used to explain and not just to stupidly try to copy.
For me, It doesn't work and I have no way of knowing why because I didn't understand anything about what I did.
