Visualization for a music in motion

I have rescued my engineering diploma work from 2002 (the link above is form an embarrassing old site and some things might not even work any longer). I actually did my research work 3 years after finishing my studies, by the time I moved to Berlin.

My work was about research and experimentation of real-time audiovisual development tools / environments, by the time Processing was released as far as I can remember. I basically used max/msp+jitter, Director+Flash, C++ and OpenGL

Anyway, I just wanted to put together a set of images from one of my little experiments back in 2002: I used Max/MSP to generate a text file out of an audio track. The text file contained an array of number trios obtained from a FFT calculation. Each trio was basically: [Lo-Freq, Mid-Freq, Hi-Freq].

I wrote a C++ program that used OpenGL to render each trio as a 3-D coordinate [x, y, z], trying different mappings and rules. Each consecutive coordinate would be linked with a line / curve and each coordinate was represented by a square that would increase its size if the identical same coordinate was found again.

The resulting mesh, or maybe better mess, was navigable in the 3D space via keyboard (should have the sources in some of my old HD).

Have your say:
