SUMMARY:An Adaptive Fast-Multipole-Accelerated Hybrid Boundary Integral Eq
 uation Method for Accurate Diffusion Curves
DESCRIPTION:Technical Papers\n\nSeungbae Bang (University of Toronto, Amaz
 on); Kirill Serkh (University of Toronto); Oded Stein (University of South
 ern California, MIT); and Alec Jacobson (University of Toronto, Adobe)\n\n
 In theory, diffusion curves promise complex color gradations for infinite-
 resolution vector graphics. In practice, existing realizations suffer from
  poor scaling, discretization artifacts, or insufficient support for rich 
 boundary conditions. Previous applications of the boundary element method 
 to diffusion curves have relied on polygonal approximations, which either 
 forfeit the high-order smoothness of Bézier curves, or, when the polygonal
  approximation is extremely detailed, result in large and costly systems o
 f equations that must be solved. In this paper, we utilize the boundary in
 tegral equation method to accurately and efficiently solve the underlying 
 partial differential equation. Given a desired resolution and viewport, we
  then interpolate this solution and use the boundary element method to ren
 der it. We couple this hybrid approach with the fast multipole method on a
  non-uniform quadtree for efficient computation. Furthermore, we introduce
  an adaptive strategy to enable truly scalable infinite-resolution diffusi
 on curves.\n\nRegistration Category: Full Access, Enhanced Access, Trade E
