Shape-aware skeletal deformation for 2D characters

This paper presents a skeleton-based method for deforming 2D characters. While previous skeleton-based methods drive the shape deformation by binding the skeleton to the shape, our method does so by propagating the skeleton transformations over the shape. In this way, the tedious process of weight selection in previous skeleton-based methods is not required. Also, the propagation allows us to consider the geometric characteristics of the shape such that local shape distortion can be effectively avoided. Experimental results demonstrate that our method allows real-time deformation and generates visually pleasing results.
