面向大众的近似可展网格曲面设计技术研究

The rapid development of prototype technology makes personalized and customized fabrication possible when convenient design tools for novices are available. In this proposal, we focus on design tools for approximate developable surfaces. Approximate developable surfaces can be obtained by bending or sewing planar shapes and have relative lower cost in fabrication. Existing design tools for approximate developable surfaces are either hard to control by novices, not ready for fabrication or slow in computation, which makes them hard to promote for personalized design and fabrication. We plan to study user-friendly design algorithms and techniques for approximate developable surfaces, including interactive editing of two-dimensional (2D) materials and three-dimensional (3D) surfaces, fabrication-aware intelligent design techniques, the relationship between geometry properties and physical simulation of approximate developable surfaces and haptic interface for designing approximate developable surfaces. We will develop a prototype system for interactive design of approximate developable surfaces and validate our system by fast prototype techniques. The key of this research is to adapt the design systems for experts to those for novices. We will focus on the combination of 2D and 3D design algorithms and interfaces, making our tools friendly to novices and feasible for fabrication.

近似可展曲面是一类可以通过弯折缝合平面形状获得的曲面，有着低廉的制造成本。随着个性化制造的兴起，优秀的近似可展曲面设计技术将进一步提高全民设计能力。尽管近似可展曲面的研究已开展多年，现有的设计工具仍难以向大众推广。其主要原因是现有近似可展曲面设计工具的可控性及实用性不高，且计算效率较低。本申请拟针对这些问题，研究用户友好的近似可展网格曲面设计中的交互技术及算法，包括平面材料和三维近似可展网格的交互编辑、面向制造的智能设计、可展曲面几何属性与物理仿真之间的关系以及力场信号输入下的设计技术，并基于所开展的研究工作，形成一个面向大众的交互式近似可展网格设计原型系统。本申请将重点关注如何改进面向专业人员的近似可展曲面设计技术，研究新的二三维联动设计算法及交互技术，提高其实用性，使之能面向大众、面向制造。
