Linear blend skinning has become a vital tool for the animation and design of 2D and 3D shapes. Unfortunately, such methods cannot deform vector graphics (splines and subdivision surfaces). Vector graphics are used throughout 2D (PDF’s, fonts, the web, illustrations) and 3D (industrial design and computer-aided design) computer graphics. We propose an efficient solution to this problem that preserves the vector nature of a shape (splines stay splines and subdivision surfaces stay subdivision surfaces). This allows the entire literature of linear blend skinning approaches to be used with vector graphics for the first time.


Songrun Liu received the B.Sc. degree in computer Science and Technology and M.Sc. degree in Software Engineering from Zhejiang University in 2008 and 2011, respectively. He is a Ph.D. student in the Department of Computer Science at George Mason University, working with Dr. Yotam Gingold.  His current research interests focus on optimization, animation, 2D/3D modeling and editing in computer graphics.
