Commissioned by and premiered at the STRP Biennale in Eindhoven, Netherlands, this piece distils a playful connection between motion and sound, both driven by the same tuning fork like vibrations in the rods.
The giant interactive forest covers 450 square meters and comprises more than 150 musical “trees” made of rods and lasers. The audience can freely explore the space, physically tapping, shaking, plucking, and vibrating the trees to trigger sounds and lasers.
Due to the natural springiness of the material, interacting with the trees causes them to swing and oscillate, creating vibrating patterns of light and sound. Each tree is tuned to a specific tone, creating harmonious sounds spatialized and played through a powerful surround sound setup. The installation is designed to bring out child-like feelings of curiosity and wonder in the audience as they learn how to interact and play within the space.
The Physics Playroom is an interactive digital installation developed for the QUT Cube, a central part of QUT's new Science and Technology Precinct.
The physics playroom is designed to provide a fun and interactive experience of some basic general physics concepts - classical mechanics, waves, fluids etc.. The installation is designed to be exploratory and collaborative.
The 12 55-inch LCD panels are touch-sensitive. Each of the touch panels, supplied by Finish company multi-touch, contains 32 little cameras. Touch recognition software analyzes a stream of pictures coming from each camera, looking for hands and fingers touching the screen. The panels search at 100hz.
The physics playroom is designed to handle up to 100 simultaneous users for a combined total of 100000 human interactions per second. Eight networked computers help to share the load. All human interaction, number crunching (particle systems, physics, audio DSP etc.), and rendering, is distributed over the 8 machines.
Each of the computers in the physics playroom is responsible for drawing a small part of the overall scene: 2048x1920 pixels of the scene to be precise. When combined, this adds up to 12288 x 3090 pixels. All of the development was done 'on-the-fly' in Extempore, as a large Cyberphysical programming "test project". The significant compute, high interaction load, and distributed synchronization challenges made this is a good "tester" for Extempore which I'm pleased to say handled everything surprisingly well.
All of the 3D assets where built by my very talented friend Warwick Mellow.
The audio is from an old Impromptu livecoding session.
