“…In addition, in Research on The Construction Process of Architectural Playground Environments (Sekiguchi, 2022), 3D scanning was used to create data on the wood, enabling playgrounds to be fabricated while analyzing the structure. Digital workflows for natural wood in construction (Larsen et al, 2020) attempted to create joints for fabricating structure that utilizes the bending of natural wood, by digitization and a robotic arm. The structure, fabricated in Biomass Boiler House (Sahu and Wang, 2015), utilizes the curvature of natural wood, was designed using data from 3D scans and was machined with a chainsaw with angle adjustment capabilities.…”

This research examines a digitalization of workflow to assist design and construction with irregular wood in its natural form at a location close to logging areas with restrictions on processing methods. Currently, wood availability is determined by closed distribution channels with standardized production. Simple and effective use of irregularly shaped branches allows us to escape this limitation. We have attempted to develop a method of building structures with the following three features with only certain branches available, limited to chainsawing and bolted joints that can be used in the mountains. First, modeling systematically irregularly shaped branches by converting photogrammetry scanned standing trees into simplified data while preserving shape features. Second, supporting assembly design of the structure by dynamic segmentation of irregularly shaped branches as parts before cutting down the tree. Third, cutting with mixed reality guidance for joints is automatically generated from assembly geometry. To test these methods we experimented with fabricating a structure from a single-standing tree with a chainsaw. In conclusion, the construction of a data flow connecting raw materials to structures was verified to be effective in realizing pre-felling design studies and simple on-site processing for the use of natural wood in mountainous areas.
