    abstract     = "Reconstruction of smooth surfaces from point sets is an important problem in many applications since this sort of data often appear in real-life scenarios. This paper presents method for solving this this problem at interactive
rates by means of second order energy minimization obtained by solving \&\#9651;2 = 0 on a discrete scalar field using an iterative multigrid approach. Every step in the reconstruction process takes place on the {GPU}. Consequently, the surface is immediately available for any standard volume visualization method utilizing packed volume textures. This eliminates the need for lare amounts of texture transfers or a costly polygonization step."
