polar coordinate effect

    Dec 07 2015 | 8:18 am
    I'm trying to wrap my video in a circular way. I am really trying to reproduce the effect in After Effects called "polar coordinate."
    To be honest, I don't really have any idea how to do this. If you aren't familiar with polar coordinates check out the start of this video, it is explained pretty well: https://www.youtube.com/watch?v=oX85So2MPZg
    Sorry for being so vague, any help would be greatly appreciated...

    I have thrown a patch together using Jitter Tutorial 39:

      Here is a [jit.gl.pix] shader that turns an image or video into a slowly rotating tunnel. It's a bit different that what you describe but there is a lot of potential with the right image/video input.
