Abstract Fluid Simulation - TouchDesigner Tutorial (beginner friendly)

[@itsvovaFilin]

thank you! it was very fast, but I watched it several times to understand everything) cool video, we are great

[@elusivepassages]

Wow that is cool

[@doinacezarap.8629]

it's so great. thank you. (finally i could do it from the first try .D)

[@DanielSteenhoff]

That's really great to hear!! Keep at it :)

[@razyelPKTM]

i recently got in touchdesigner thing and love your tutorials, I would like to see more like reaction diffusion stuff

[@DanielSteenhoff]

Lovely to hear you like my tutorials! I will see if I can dive into reaction diffusion stuff, although I'm not super experienced with that. I think paketa12 has a cool tutorial on something like that!

[@arshinazizi]

Great , useful and short tutorial.thanks for sharing 🎉

Question -- I set the resolution to 1280x1280 because I am working off of the free version. Why is it that when I introduce ramp, the final output size seems to change from the 1280x1280 square to a rectangle? Thanks for the tutorial! Super helpful and easy to follow. Looking forward to more

[@DanielSteenhoff]

Hi there! Operators that "create" an image have their own resolution. So a circle, a noise, a ramp etc. Everything that gets an input and changes something uses the resolution of its input. The resolution of your Ramp TOP is probably something else. Connecting this to the lookup will mess with the resolution. I think it takes the lowest resolution of the two inputs. By using your scroll wheel button you van click on every operator to get info about it. Here you can see the resolution. This often helps me troubleshooting. But long answer short, just change the resolution in your ramp TOP. Good luck!

Wonderfull Short Video !!!! Very Thank you !!! I hope you forever Happy !!! So Thank You !!! Have a Nice Day !!!!

[@skotomogilnik]

Cool lesson, thanks!

[@tsuididi0120]

Amazing tutorial!!! Can i ask for a question? How can i change the color by loop it

[@DanielSteenhoff]

Thanks a lot!! Are you referring to the Lookup TOP? If so the color changes depending on the second input. In this case I put a ramp TOP there. So changing the values in the ramp TOP changes the color. Hope this helps and apologies for the late reply :)

Hello, I'm enjoying the video. How should I change the count value at 0:41 in the video? I tried to make it similar in the count limit window, but the noise doesn't move like the video. How can I fix this??

[@DanielSteenhoff]

Have you filled in absTime.seconds/10 in the third box of the translate parameter of the transform tab?

[@tokkenn8513]

awesome tutorial. would I be able to replicate this, but change the "keyboard_in" for a "audio file in", so I can make this simulation reactive to sound?

[@DanielSteenhoff]

Thanks! There are two ways you could easily make this audioreactive: 1. Grab your audio file or device in. Connect it to an audio spectrum chop, then an analyze chop, then a lag chop, then a math chop, then a speed chop. Now you can connect the value of the speed chop to the third translate parameter under the transform tab in the noise. You can now play with the input range and output range of the math chop to make it react more or less. 2. If you want to use this resetting look you get by pressing the keyboard, try looking for the "AudioAnalysis" (I believe that is what it's called) under the folder tools in the pallette.) Now activate kick, connect a null chop to it. Now everytime a kick gets detected it triggers and basically gives the same value as pressing the keyboard in. Connect it the same way as the keyboard in. Make sure to reset the feedbackloops with the kick. Good luck and let me know if you have questions :)

thank you so much man, it really helpful

[@DanielSteenhoff]

Glad it helped, have fun with it :)

[@hera-io]

Thank u so much! Amazing tuto c:

[@DanielSteenhoff]

You're welcome!

[@egemenkocamaz9009]

great inspiration ty man

[@DanielSteenhoff]

Thanks, and you're welcome!

[@Tutybanana]

Hey Daniel, thanks for the tutorial looks great. Do you think its possible to wrap it around a circle as a texture?

[@DanielSteenhoff]

Hey there! Try disconnecting 'noise1' and 'comp1'. Now create a circle TOP and connect it to 'comp1'. This should give you a somewhat circular shape. You could always use the same trick at the end of the network. So add in a composite TOP and connect the output of our network and a circle TOP. This wil result in a harder edge. Your choice :)

[@Tutybanana]

thanks alot for your reply! @@DanielSteenhoff

[@cmolfino]

so feedback edge is a built in filter? I was trying to mimic the fx in Houdini until you add that node...

[@DanielSteenhoff]

All the "built in" tools are just networks of existing operators. You could probably also mimick fbedge but it would take more time. If you download td and drag the feedbackedge in and double click on it, you can see the network. Hope this helps. Also really cool your trying to recreate it in houdini!

[@omerbayramoglu7416]

connecting count to noise doesn't work for me; how can I fix it?

[@DanielSteenhoff]

Does the count increase when you press 1? If so make sure to click the little star on the bottom right of the count that says "display" then click and drag the value on to the seed of the noise. Then select "CHOP Reference". Hope this works. If not, I need a bit more information what part is not working.

[@mackdellirious]

Thank you sir!

[@DanielSteenhoff]

You're welcome! :)

[@Flor-ly5cg]

could you do the same with a geometry instead of abstract lines?

[@DanielSteenhoff]

Hey there! I'm not sure I fully understand what you mean. But you can absolutely play around with some kind of straight lines at the beginning of the network. But I have to say that the most of the effect is quite organic/abstract so tuning it to be geometric would alter it to a completely new network. However I am planning on making tutorials that focus more on geometric content. Let me know if you still have any questions! Daniël

[@ljezyna]

i doesn't let me link the count with noise sample somehow do u know what can be wrong?

[@DanielSteenhoff]

Make sure you click the little star in the bottom right corner of the count. Then drag the value from the count on the noise TOP seed, click chop reference. This should do the trick. If it still doesn't work could you be more specific as to what exact step is not working? I'll try to help you out :) Daniël

[@pablop3159]

​@@DanielSteenhoffhey nice video, I got the same issue. Even with the little white star, if I drag the count to the seed, it just goes red and don't open the tool bar... Instead I just get a text bar with "op('count1') but doesn't change the seed when I press 1.

[@havvaaydogan4608]

youre great thanks

[@abdesslemtrabelsi8341]

Great tutorial, can we make it interactive with kinect?

[@DanielSteenhoff]

In theory you can make everything interactive with a kinect, but I think it would be quite a different network to achieve this. This is currently just based on some simple noise which in itself is not directly tweakable with a kinect. You can try to follow kinect based tutorials and implement the first steps there and then give it the same post chain as I used. Hope this helps

[@rayiskadir]

Hi just did this on TD, now I don’t know how to project this through kantan mapper, I’m new to TD. Thanks for the tutorials

[@DanielSteenhoff]

Hey! I haven't worked a lot with the kantan mapper, but I know there are some great tutorials out there. Just search for "Kantan Mapper TouchDesigner" or something, you'll figure it out :) Oh and if it's just a test setup you can download Resolume Arena and do your mapping in that program, but it will have a watermark every minute unless you pay for it.
