Test movie


Sound visualization _fluid from koosi_lab on Vimeo.

There are still some issues about noise echo and getting sound input.
The input only works when the sound really loud but loud sound gives noise echo.
it's like looping problem.
And i don't know why the video get noises when it gets high level.
Plus, I think the movie should be more dynamic(rotation maybe?) and bigger.

Concept

Melting / Fluid / Flexible

this is an experimental test for the concept
I made a fluid movie in Maya and time displacement(slit scanning) effect in After effect.

Process

I made a movie in Maya.

I used sphere surface and lattice to make a distortion which gives a feeling of melting or fluid.
then, appied a texture has transparency that shows backside which has more depth.
I can change the pattern whatever i want.

I don't know why the time displacement didn't work well in this video so i didn't use it. Maybe it's because of color..?

Interaction

Sound level controls the frames and opacity.


Because I couldn't know about Quartz composer well, I couldn't control images as much as I want.
so I decided to change into Flash and movie.

First of all, I need to connect to sound and Flash,
