This paper focus on improving the traditional papercraft technique of approximating smooth surfaces with discretised planar meshes. The necessary step to unfold strips of planar faces often creates many separate pieces. These pieces require tedious manual work in gluing and assembling them together. The addition of gluing tabs also results in an aesthetically unpleasing underside of the surface. This paper proposes a double-shell construction to overcome the challenges of edge jointing and eliminate the need for gluing tabs. A double-shell is created using two sets of unfolded planar strips that were split at different seams. When the two sides are folded and glued back together, the folded connections bridge the seams on another side and vice versa. Spray-on contact adhesive can be globally applied to the underside of each set, thereby speeding up the assembly process. Models of trimmed and untrimmed NURBS surfaces and triangular mesh surfaces are constructed using this method as demonstration. Quantitative and qualitative effect of model size and paper thickness are explored to provide baseline application parameters. As a result, this method allows anyone with a laser or drag knife cutter to rapidly create mesh models that are easy to assemble and aesthetically clean on both sides.","PeriodicalId":268751,"journal":{"name":"Proceedings of the 2nd Annual ACM Symposium on Computational Fabrication","volume":"329 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133534695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a method that creates linearly foldable polyhedral nets, a kind of unfoldings with linear collision-free folding paths. We combine the topological and geometric features of polyhedral nets into a hypothesis fitness function for a genetic-based unfolder and use it to map the polyhedral nets into a low dimensional space. An efficient learning strategy is used to optimize the fitness function to produce the optimal nets. We experimentally demonstrate that the proposed method can find linearly foldable nets for highly non-convex polyhedra with substantial complexity. The technique presented in the paper will provide a powerful tool to enable designers, materials engineers, roboticists, to name just a few, to make physically conceivable structures through self-assembly by eliminating the common self-collision issue. It also simplifies the design of the control mechanisms when making deployable shape morphing devices. Additionally, our approach makes foldable papercraft more accessible to younger children and provides chances to enrich their education experiences.","PeriodicalId":268751,"journal":{"name":"Proceedings of the 2nd Annual ACM Symposium on Computational Fabrication","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131649406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
