The igloo is a prototype of a triangulated surface after several video-tutorials on digitaltoolbox.info. A loft surface of three curves is divided in U/V direction into a point mesh. The resulting points are connected to triangular surfaces which are re-oriented and tagged on (a) plane surface(s). With the "Offset" component tabs are created to connect the cutted parts easily with a compressed air staple gun. The project was realised in 3 Master course hours of 'bauen mit computern' with a group of 3-6 students.
