Skinning Cubic Bézier Splines and Catmull-Clark Subdivision Surfaces

Abstract

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.

*Bio*

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.

Note: This paper is to be presented at ACM SIGRAPH Asia 2014 in December
