How to make lines flow in quartz composer (for video mapping)

Hi,

I would like to compose something like in this movie:

watch the lines move at 00:15

How can you do this?

Thanks!

Lucas

You might want to try with a Timeline and Kineme GL Lines. But, if there's a more efficient way, I would be glad to know it too.

Yes, I think this is a good approach.

store your N vertices in a javascript structure Sin
output from the JS a vertices structure Sout of 0-M points, with M<N. The M-th vertex coords (of Sout) will be interpolated between the M-1-th vertex and M-th vertex of Sin, based on timeline input.
link Sout to GL line structure, and you'll have the effect.

In the video I think that what you see is a movie, that is correctly projected and mapped onto the 3D structure.

Thanks!

Yes but I wanted it in Quartz Composer! :)

I think you've misunderstood the advice given above by benoitlahoz and LukeNeo.

The advice they gave is applicable within Quartz Composer.

@LukeNeo It's also a product of some be-spoked in-house coding and such by the Brazilian company that made that lovely moving lines projection.
