我们提出了Draco，这是一个基于素描的界面，可让艺术家和休闲用户在其图纸中添加丰富的动画效果，从而使插图栩栩如生。虽然以前的系统已经为单个对象引入了基于草图的动画，但我们的贡献是一个统一的运动控件框架，允许用户无缝将协调的动作添加到对象集合中。我们提出了一个围绕动力学纹理建立的框架，该框架提供了连续的动画效果，同时保留了静止插图的独特永恒性质。这使得许多动态效果都可以使用以前的基于草图的工具（例如鱼类游泳学校，风在风中吹树或池塘里荡漾的水荡漾）来难以或无法进行。我们描述了我们的实现，并说明了它支持的动画效果的曲目。与专业动画师和休闲用户一起研究的用户研究展示了我们工具提供的动画，应用程序和创意可能性。
We present Draco, a sketch-based interface that allows artists and casual users alike to add a rich set of animation effects to their drawings, seemingly bringing illustrations to life. While previous systems have introduced sketch-based animations for individual objects, our contribution is a unified framework of motion controls that allows users to seamlessly add coordinated motions to object collections. We propose a framework built around kinetic textures, which provide continuous animation effects while preserving the unique timeless nature of still illustrations. This enables many dynamic effects difficult or not possible with previous sketch-based tools, such as a school of fish swimming, tree leaves blowing in the wind, or water rippling in a pond. We describe our implementation and illustrate the repertoire of animation effects it supports. A user study with professional animators and casual users demonstrates the variety of animations, applications and creative possibilities our tool provides.
