| summary |
Although digital fabrication has a booming development in the building industry, especially in freeform building, its further application in onsite operations is still limited because of the huge flexibility required in programming. On the contrary, traditional manual fabrication onsite deals perfectly with problems that always accompany fatal accumulative errors in freeform building. This study explores a hybrid fabrication paradigm to take advantage of both in an onsite freeform building project, in which there is a cycling human–computer interactive process consisting of manual operation and computer guidance in real time. A Hololens-Kinect system in a framework of typical project camera systems is used in the demonstration. When human builders perceive, decide, and operate the irregular foam bricks in a complex onsite environment, the computer keeps updating the current form through 3D scanning and prompting the position and orientation of the next brick through augmented display. From a starting vault, the computer always fine tunes its control surface according to the gradually installed bricks and keeps following a catenary formula. Thus, the hybrid fabrication actually benefits from the flexibility based on human judgment and operation, and an acceptable level of accumulative error can be handled through computer guidance concerning the structural performance and formal accuracy. |
