A sketching interface for articulated figure animation

We introduce a new interface for rapidly creating 3D articulated figure animation, from 2D sketches of the character in the desired key frame poses. Since the exact 3D animation corresponding to a set of 2D drawings is ambiguous we first reconstruct the possible 3D configurations and then apply a set of constraints and assumptions to present the user with the most likely 3D pose. The user can refine this candidate pose by choosing among alternate poses proposed by the system. This interface is supported by pose reconstruction and optimization methods specifically designed to work with imprecise hand drawn figures. Our system provides a simple, intuitive and fast interface for creating rough animations that leverages our users' existing ability to draw. The resulting key framed sequence can be exported to commercial animation packages for interpolation and additional refinement.

我们介绍了一个新界面，用于快速创建3D铰接的图形动画，从所需的关键框架姿势中的角色的2D草图。由于与一组2D图相对应的精确的3D动画是模棱两可的，因此我们首先重建可能的3D配置，然后应用一组约束和假设，以向用户展示最可能的3D姿势。用户可以通过在系统提出的替代姿势中进行选择来完善该候选姿势。该界面由姿势重建和专门设计的姿势重建和优化方法支持，用于与不精确的手绘数字一起使用。我们的系统提供了一个简单，直观和快速的界面，用于创建粗略的动画，以利用用户现有的绘制能力。可以将最终的框架序列导出到商业动画包中，以进行插值和额外的细化。
