Vortex or Circle TOP loop

[Keito07]

How can I make circle loop to the center? Feedback works but it can’t make an animation of them going to the center if I use absTime.seconds in size parameter of the transform.

You can also use either LFO Chop or Timer CHOP to control the transform parameters as you like.

It will give the same result as using absTime.seconds and won’t solve the problem. Issue here is in looping the circles so they infinitely go to the center.

If you’re trying to get each of the circles in the feedback loop to feel as if they’re all pulling to the center over time, you could try injecting the parent circle only occasionally into the feedback loop. In the interim, send it a transparent image, it’ll have the effect of creating a continual cascade of circles moving to the center of the image.

Thank you, but that’s not really what I try to achieve. I expect circles to come from the outside of image and continuously shrink to the center

If I understand correctly, I’d solve this with a ramp and a lookup TOP.

Hi @Keito07

Just to add to it:

• use a Ramp TOP and set the Period parameter to a small enough amount to your liking
• move the right hand notch in the ramp tool to the center
• set the Interpolate Notches parameter to “Step”
• animate the Phase parameter by something like -absTime.seconds
