More audio visualisers! Yeey!

Early December last year Marcelo invited me to join his Omega Code project where lots a visual artist were going to create a illustration/poster for each of the track on the band's first album.

My take on the project would be creating a visualiser for the website. Although at first I planned to create a tool to get some curves to match each track (which is something I want to do this year) I ended up running out of time and had to go back on trying to get the best out of the FFT.

On top of that, ever since the first time Ithaqua quickly explained on a random forum (spanish) his way of animating octopus-ish meshes in 3D I always wanted to implement it and this time, and as most of the posters were quite circular, this seemed to be a good opportunity.

If you're wondering how have it's done here it's a quick explanation. Imagine having 20 spheres each one slightly bigger than the previous one; all of the centred. Now hide them and draw lines from each point in between each sphere. That would be a line from the point 0 of the sphere 0 to the point 0 of the sphere 1 and so on. You'll end up with a hair ball. Unfortunatelly, the drawing API of flash is a bit slow and it will be a hair ball of 20 or so hairs. From there you should be able to guess the rest :)



Once the effect was done, it was a matter of spending a lot of hours tweaking parameters, testing with different tunes, and finally quickly integrating it with the website interface developed by scarpelini.

I hope you find the end result as mesmerising as I do :)
