HoloDecks from Lukasz Karluk uses OpenFrameworks to create 3D-printable sculptures from sound:
HoloDecks is an umbrella project for a number of studies which focus on transforming sound through different mediums.
This study begins with a custom application built in openFrameworks which visualises audio from a song by Oneohtrix Point Never, titled Zebra. The base shape chosen for the visualisation is a disc which has always been a ubiquitous shape associated with music storage formats such as compact discs and vinyl records. Audio data from the song displaces the geometry of the disc to create a swirly visual echo of the audios last few seconds.
At any point in the visualisation, a snapshot of the generated 3d model can be taken. OpenFrameworks does a great job at exporting 3D models using the .ply format which then needs to be converted into .obj format so it can be printed with a Makerbot 3D printer.
Up to this point, the sound has been transformed from pure audio data, into a software visualisation and then materialised into the real world using a 3D printer. A final transformation is undertaken by augmenting the 3D printed sound sculpture using a mobile device to see another layer of audio reactive visuals mapped to the object.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
