What Is Feedback? Overview and Using Feedback TOP in TouchDesigner for Visual & Interactive Creators

In this tutorial, I’m going to explain how to create three simple techniques using feedback Get Project Files & Components on my Patreon 👉 / okamirufu
Summary
This tutorial explores three feedback techniques in TouchDesigner: infinite mirror effects, motion trails, and simulating decay and dissolve effects. We start with a simple mirror analogy to explain feedback and demonstrate creating dynamic visuals with basic operators. You’ll learn how to duplicate and transform components to create intricate patterns. Feedback is a powerful tool for generating organic and evolving visuals, perfect for live performances and generative art.

Love the retro moments

Thanks! this will be a think in my tuts

your channel is a life saver

[@OkamirufuV]

Thank you! I hope you're learning a lot. I’ll keep working on making better and better tutorials

Ciao from Italy, many thanks for your tutorials. This feedback is really explanatory and super comprehensive. Wow. Thanks again.

[@OkamirufuV]

Ciao, che piacere sapere che hai goduto il tutorial, woo e che bella lingua è l’italiano, una volta ho provato ad imparare ma ho dimenticato la maggior parte (ho usato il traduttore per scriverti questo messaggio), spero di vederti continuare a seguire il canale

[@freivonstil]

I love your style of explaining!

[@OkamirufuV]

Thank you!, i hope you enjoy the rest of the videos as well ٩(◕‿◕｡)۶

[@okjaak]

amazing videos, thank you! one note though - the background music is quite repetitive, it would be easier to focus on the amazing tutorial with no music or something more ambient :)

[@OkamirufuV]

got it, man. now that I think about it i should go with something more ambient so the music doesn't distract. Thanks for the tip.

[@maxschiller9679]

@@OkamirufuV i loved the background music, was a blast

[@afewhourslater_dion]

The whole lecture is so sleek. You just killed 70% of college classes with 15 minutes.

[@OkamirufuV]

Haha thanks mate, 70% is crazy, and I feel like I'm only giving 20% so far. I just hope I can quit my two jobs soon to dedicate myself to this 100%.

[@fukishatubo2389]

this is worth more than my 5 years at uni lol

[@OkamirufuV]

That's by far the best and most motivating comment I've received lately! I hope I keep helping others shave off more years of uni , haha!

thank you for this great tutorial! i am wondering how do you get it so you can see your output on the side of your screen? the only way i can see mine is by going to a full screen window of it. thanks again!

[@OkamirufuV]

Hi man thanks for the comment, i show you this in my last tutorial, What is Noise

[@arshinazizi]

Wow , so theoretical tutorial about feedback .... I wanna learn like this , learning logic of every operator Thanks for sharing your knowledge. ,i appreciate it man 🎉

[@OkamirufuV]

Ok it could be possible except with the null operator (￢_￢;)

how to do this in AE

[@OkamirufuV]

Mmm, good question. But now I am completely focused on a real-time approach, which is why I exclusively use touchdesigner

[@a3haus]

Try the echo function

[@nathangorey8732]

This will get you a similar 4 second loop of the color changing circle with trail: Make a new comp (1920x1080), duration of 4 seconds, 60fps Create a black background by either making a solid (command + y), or making a shape layer with a black rectangle that covers the span of the comp Create a new shape layer with a circle, and center the circle in comp. Create some keyframes on the circle’s fill color (so there is a new color every ½ second, for example), and have the final keyframe color at the end frame be the same as the starting color on frame 1 (so it loops) Add a transform effect and add some keyframes to the scale property. Start at 100%, 1 second 0%, 2 seconds 100%, 3 seconds 0%, 4 seconds 100% (to create a loop) Add a second transform effect to the circle shape layer, translate circle away from center (200px to the right, for example) On frame 1 of the comp, create a keyframe on this second rotation property of the transform effect On last keyframe of comp, create a keyframe that creates one full revolution (1x +0.0 degrees). The circle will now make one full revolution around the center point of the comp in 4 seconds Add a Gaussian blur effect, uncheck maintain comp edges (not the exact wording, not at my computer). Dial in some blur to soften the edge of the circle (maybe 10-20?) Add an echo effect. Change the blend mode to maximum, or blend. Change the delay time to somewhere between -.02 and -.05. Number of echoes around 30, and decay between .6 and .9. Will have to play with it. You could also add a second Gaussian blur effect now to further soften the edges. Hope that helps, lengthy directions but really not that complicated once you set it up! By using transform effects on the layer, you still have the ability to use the layer’s native transform properties (position, scale, rotation) freely. You could do the same thing with a precomp, but in the event you want to composite/layer this method ends up being less CPU intensive as it’d be pulling from one instance of the echo FX chain.
