一种支持纸的折叠、剪切与展开的计算模型

A Computational Model for Paper's Folding,Cutting,and Unfolding

为了满足儿童剪纸方案的交互设计以及向儿童展示典型的儿童剪纸过程的需要,设计了一个支持纸的折叠、剪切与展开的计算模型,它包括当前纸态的几何与拓扑数据结构、操作过程的记录方法以及各相关功能的实现算法。以此计算模型为核心所开发的原型软件(命名为Virtual Paper)验证了该模型的可行性。

For satisfying the requirements of interactive design of children＇s paper-cutting projects and demonstration of classic fold-and-cut processes,a computational model for simulating paper＇s folding,cutting,and unfolding is presented.The model consists of a data structure for geometrically and topologically representing the current paper configuration,a method for recording the process of operations,and a series of algorithms for implementing related functions.A prototype system named Virtual Paper is developed with the model as its core to test the feasibility of the model.
