Circles, trails & Leap Motion

Beginners
1

Hi All,

I’m trying to create a simple interactive experiment which allows the user to draw art using a basic circle and a leap motion. I’ve seen tonnes of examples of this kind of thing done in Processing, but not in TD. It’s my first time to try leap!

I’m trying to achieve SOMETHING like this (In terms of look, not the interaction) : openprocessing.org/sketch/529561

I’d like to know :

  1. How to have the circles remain on screen longer, rather than just an echo style with the feedback loop. Is there a better technique for this?

  2. I created the circle as a SOP since I may add 3D rotation. Should I consider using circle TOP instead to cut down the amount of memory? If so will I still be able to still rotate in x,y,z?

  3. How might I add inertia to the position data coming from the leap to give it more springy-ness?

Any pointers greatly appreciated.

Hi! For a kinect installation we created a path based on the position of a tracked point. Once this path is recorded you can connect al kinds of sop shapes to it using a instancer. There is a “gestureCapture” component in the palette that lets you record incoming movement and translates it to a path. I’m sure there are tons of other approaches to realize the effect you are looking for. Think this will get you on your way to dive into one way of doing it.

Thanks for the response Boompje and the tip on the gesture component. I’m attempting to pull that apart to get some understanding (although it’s quite a dense network for my skill level!)

Would you happen to know how I might get the “draw over” effect to extend longer than a feedback loop? I’m hoping to have the circles remain where they were drawn for “X” amount of seconds before fading away (Or even scaling).

Any ideas how I might achieve this?
