iBamboo : proposing a new digital workflow to enhance the design possibilities of irregular Bamboo materials—from scanning to discrete to topological

Abstract

Raw bamboo, a biomass building material with ecological degradability and rapid growth, is crucial for promoting a circular economy and sustainable environments. However, its non-standard nature limits standardized design and mass production. To overcome this, our study introduces a modular bamboo design workflow utilizing digital design technology to address geometric variability. The workflow incorporates 3D scanning to convert raw bamboo forms into precise geometric data, analyze their geometric parameters and connection methods for modular design, and apply discrete–topological shape-finding and aggregation for iterative optimization in batch production. We explore how XR assists in visualizing bamboo furniture designs, the benefits of 3D scanning, discrete design principles, and strategies for material integration. Our methodology includes material analysis, form finding, optimization, and a parametric workflow to enhance adaptability and innovation. The process covers 3D scanning raw bamboo, designing discrete units and connection rules, and aggregating units via topological optimization. This study highlights how modern digital technologies and innovative methodologies can enhance bamboo furniture design. These approaches promote more effective and diverse solutions while addressing the inherent limitations of the material.
