Sketch-n-Stretch lets novices quickly and easily create 2D animations. The system has a seamless two-layer drawing interface that supports cutouts using a whiteboard metaphor. Cutout animations serve as building blocks to help users construct sophisticated animations. While manipulating cutout animations, users can draw and write text to create effects-such as articulated figures, multiple motions, and image objects-that have been difficult with previous sketching approaches. An intuitive timeline interface employs visually integrated motion cues and supports several traditional animation effects. Novices positively evaluated Sketch-n-Stretch's effectiveness in creating object motions, compared to an existing sketching tool. They also used its advanced features to animate complete stories. This video demonstrates the Sketch-n-Stretch tool for making sketch-based animations.
Sketch-n-Stretch让新手能够快速轻松地创建二维动画。该系统拥有一个无缝的双层绘图界面，它使用白板隐喻来支持抠图。抠图动画作为构建模块，帮助用户构建复杂的动画。在操作抠图动画时，用户可以绘制和书写文本，以创建诸如关节人物、多种动作和图像对象等效果，而这些效果用以前的草图绘制方法很难实现。直观的时间轴界面采用视觉上集成的运动提示，并支持多种传统动画效果。与现有的草图绘制工具相比，新手对Sketch-n-Stretch在创建对象运动方面的有效性给予了积极评价。他们还利用其高级功能为完整的故事制作动画。本视频展示了用于制作基于草图的动画的Sketch-n-Stretch工具。
