Converting the motion into mesh and 3d printable object.

openCV + ofMesh +Grasshopper

A webcam collects the information when the movement occurs. It does it by calculating frame differences which is the information of the changes made in pixels that webcam collects at each frame.
The vertices of the shape is then collected and added into a point cloud and where each points are then connected to the neighbouring points.

Z-axis moves in a time-base, that every newly added points are in a new layer, producing a time-based 3d structure.
