Basic particle system with GLSL TOP (Touchdesigner tutorial)

Рет қаралды 45,459

Күн бұрын

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!

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 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 :)

nvm I got it. My problem was the line "pos += vel * step", I had "pos += f * step"

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!

@noonesimg 3 жыл бұрын

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.

um, can i ask what is it with reoder, because i don't understand about that. i try it, great video btw.

@noonesimg 3 жыл бұрын

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.

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..

Sorry, I don't think it's possible. Compute shaders require OpenGL 4.3+, and MacOS supports only 4.1

Error: All OPs must generate the same number of instances (have the same lenght)

@paolabelviso7465 Жыл бұрын

Because you have to put the same resolution as the pos and the vel, the standard resolution of the Ramp is 256x256

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.
