As predicted by a physicist Michio Kaku in his book “the Future of the Mind”, construction using Augmented Technologies have started become common practices for architecture. Augmented Tectonics workshop will explore the construction processes within Mixed Reality environment. The workshop will be fabricating complex steel structure with attaching spray concrete panels, assembled through Augmented Reality technique using Hololens and Fologram (a Rhino/Hololens plug-in). “Augmented Tectonics” will explore the construction processes using Augmented Reality Technologies, fabricating steel structure and attaching precisely fabricated spray concrete panels. Our team has a combined background of design, fabrication and engineering, highly experienced with digital fabrication. Participants will be physically producing a 1:1 scale structure in TongJi University Campus exploring ways of using mixed reality to help designers to physicalize complex geometries that has been excluded for a while in CNC dominated digital fabrication research.
