Motion data was captured using inexpensive sensors and that data paved the way through an extensive number of steps. Once all the scanned point cloud data was combined, that was then used as the base for the creative development on the piece. A series of iterative studies on styles followed and several techniques and dynamic simulations were then applied using a number 3D tools for various results.
