A mobile environment for sketching-based skeleton generation

Abstract

Articulated character animation is typically performed by manually creating and rigging a skeleton into an unfolded 3D object. However, such tasks are not trivial, as they require a substantial amount of training and practices. Although automatic skeleton extraction methods have been proposed, they generally may not guarantee that the resulting skeleton can help produce desired animations according to user intention. In this paper, we present a sketching-based skeleton generation method suitable for use in the mobile environment. This method takes user sketching as an input, and based on the mesh segmentation result of a 3D object, it estimates a skeleton for articulated character animation. In addition, we are currently developing a Web-based mobile platform to support mesh editing by a group of collaborative users and we depict the system architecture of such a platform. Results show that our method can produce better skeletons in terms of joint positions and topological structure.

Advances in ubiquitous media technologies and applications

“…The third paper [19], "A Mobile Environment for Sketching-based Skeleton Generation," by Zheng and Li (Durham University, United Kingdom) proposes a Web-based collaborative platform to support mesh editing in a mobile environment based on a novel sketching-based skeleton generation method. The proposed method can accept rough and imprecise user sketches as inputs and produce semantically meaningful bones and joints to form a skeleton for a 3D object that may be in any arbitrary pose.…”
