Outline
Sound travels as compression waves through gases and liquids. Stable in its immateriality it remains true to its original data. Here sound input has a stronger power over a flow field. Liquid Sound Collisions sends two audio files as vibration source into a fluid simulation. The waves created by the sound files run towards each other, collide and interfere with each others patterns. A snapshot of the collision is translated into a 3D model.
The selected audio files are spoken words of dualistic views: chaos and order, mind and body, determinism and indeterminism etc. The simplicity of understanding the world as divided into two categories is countered here with the display of the turbulent flow that arises between the two extremes.
Process
|
I used Memo's MSAFluid Library for Openframeworks to create a simple 2D fluid environment. The sound inputs are located at the top and bottom part of the screen and the sound vibrations directly effects the velocity field of the fluid. The screenshot shows the fluid in motion after two sound waves were released into it and collided around the center of the field.
|
|
Using the velocity data from the fluid simulation a 3dimensional landscape was created.
|
|
The same data is then mapped around a cylindrical form. And exported as a STL file.
|
|
The form was then modeled out of Styrofoam with the Roland MODELA MDX-15 desktop milling machine. The model on the left shows the roughing stage of the milling process.
|
|
Another model after the finishing process with a smooth surface. This particular object depicts the spoken words 'objectivity' and 'subjectivity' colliding in the fluid.
|
|
Here are two of the resulting objects, ready to presented at our open house at the BNMI.

Now also in 3Dprinted form!
