Skeleton creation is an important phase in the character animation pipeline. However, handcrafting skeleton takes extensive labor time and domain knowledge. Automatic skeletonization provides a solution. However, most of the current approaches are far from real-time and lack the flexibility to control the skeleton complexity. In this paper, we present an efficient skeletonization method, which can be seamlessly integrated into the sketch-based modeling process in real-time. The method contains three steps: (i) local sub-skeleton extraction; (ii) sub-skeleton connection; and (iii) global skeleton refinement. Firstly, the local skeleton is extracted from processed polygon stroke and forms a subpart along with the sub-mesh. Then, local sub-skeletons are connected according to the intersecting relationships and modeling sequence of subparts. Lastly, a global refinement method is proposed to gives users coarse-to-fine control on the connected skeleton. We demonstrate the effectiveness of our method on a variety of examples created from both novices and professionals. (C) 2021 Elsevier Ltd. All rights reserved. |
