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.
