摘要:针对制作手工剪纸动画背景效率低、耗资大的问题,提出了一个计算机生成剪纸风格动画背景的方法。首先对构成手工剪纸动画背景的剪纸图案进行分类,包括种类繁多的树、花、草、山石、建筑等,然后用计算机方法生成这些模型。用户创作时,可从系统的剪纸背景图案库中导入所需模型放入指定位置,再通过少量交互,确定图案的大小方向以及各种其他属性。研究结果表明,采用此系统,通过将各类剪纸图案放入不同的位置,便可灵活且高效地组合出不同的剪纸动画背景图。

Abstract: Aiming that handmade Chinese paper cutout is an inefficient and expensive task, a method was proposed for generating animation background with the style of papercuts by computer to emulate handmade papercuts. First the papercuts graphics of animation background were classified with the style of papercuts, including a variety of trees, flowers, grasses, mountains, bridges, and so on. Then these models were generated by computer. Models could be chosen by users from the library of papercuts graphics, and be put into specified location, and their size, direction and other property were adjusted by a few interactions of users. The results indicate that adopting this method, users could build up a variety of animation background with the style of papercuts by putting different papercuts graphics into different location.
