Hello,
i am completely new to touchdesigner, i have been using it for 2 weeks (while going to school and working) so i am not relly good at it.
I would like to make an onion skin effect, just like when you animate - it creates a trail that fades out in a few seconds.
I connected my kinekt v1 already and edited it with level tops and a threshold top, so now it looks like a shadow.
i tried a feedback loop, but it always follows the person, i want it to create a trail.
I tried using cache top but it creates the same problem, it just follows but it doesnt stop in place.
Unfortunately i can not find ANY tutorials for this. (CHATGPT also isnt any help lol)
Does anyone have any tips or an answer on how to do this please?
I would appriciate anything haha. Thank you
Sounds like you want to archive somethink like this? https://www.youtube.com/watch?v=GQ-y0FYsCfw&ab_channel=ScottAllenVisualArt
thank you, this is similar to something i tried out.
when i move, it does do the first impression of an onion skin - it create the trail but the trail comes back, it doesnt freeze in time and dissapear. it follows me instead of freezing. im not sure if my explaining makes sense.
I’m really not sure what you’re trying to archive/ what the issue is. But it sounds like you might want to double check the compositing, potentially with respect to how you use the alpha channel.
Do you want all frames to accumulate? Such that you kind of draw with your body?
I think so, yes. if a ball would go from one side of the screen to another, you could be able to see the route for a few seconds. before it disappears. so in a way, anything that moves should be able to draw with itself.
I don’t see how that differs from the tutorial I shared. Execpt for the transform and coloring that you might not want to have.
this is probably the first step to what i want but the “duplicates” of the hand follow me. like if i move it it creates more hands but they always come back to the outline of my hand. i would like it to stop there. like when i take a picture of it. it stays there and it creates a visible path of my hand that stays in the final composition. so you can see for like 1 seconds the exact path of what i did without the duplicate outlines coming back to my actual one.
