Lumarca Community Building
Community-based construction of a 3-dimensional projection display
Lumarca is a volumetric display by Matt Parker and Albert Huang that uses projection onto a field of strings to create an illusion of depth, which effectively turns a 2-dimensional projection into a 3-dimensional display.
As part of the assistantship with the Interactive Media department at NYU Abu Dhabi, I led a Lumarca community building workshop following the construction guide provided by the Lumarca authors. The purpose of the workshop, which ran over a weekend, was to learn by doing and thus foster the maker attitude among Interactive Media students at NYU Abu Dhabi.
Built with : wood, yarn, foam core, Processing
The projection display was showcased during an Open Studios night at NYU Abu Dhabi's arts center.

The success of the project depends the precise positioning of the string display field in relation to the projector
A computer program has the positions of strings memorized, which forms the basis of depth projection. Here, the strings are either green, red, or blue depending on the distance from the projector
The light wraps around the strings, which makes the projection visible from any angle
The position of the virtual sphere in the 3d field corresponded to the user's tracing of the finger on a trackpad.
