Abstract
In recent years, personalized fabrication has attracted much attention due to the greatly improved accessibility of consumer-level 3D printers. However, consumer 3D printers still suffers from the relatively long production time and limited output size, which are undesirable factors to large-scale rapidprototyping. In this paper, we present an efficient method to approximate a given 3D shape with Zometool. To achieve ease of assembly and economic usage of building units, the proposed method generates the Zometool structures through a higher level of shape abstraction. The input model is first partitioned into a collection of generalized cylinders by mesh segmentation. The boundaries of mesh segments are converted into ring-like structures and inter-linked by finding the shortest path between them. Additional ring structures are then added along the representative axis of each segment to better approximate the underlying 3D shape. We demonstrate the effectiveness of the proposed method by a variety of 3D models along with examples of the physically fabricated objects.
