Hi,
Has anyone written an easy way to export positions from Processing to After Effects? I'm experimenting with some augmented reality scripts, where a marker's position can be grabbed in 3D, and an object positioned on top of it - e.g. here:
http://vimeo.com/34618110
I've managed to get the matrix positions echoing to the debug window, using printMatrix(); but I'm wondering if there's an easier way to get the movement data into After Effects, and maybe someone has already written some scripts to achieve this?
Many thanks,
Tom

- This sample program is most small sample as simpleLite.
- The marker is "patt.hiro".

I've updated the blog post to include some more info on changing the paths, cause I was indeed getting several questions about it.
