SUMMARY:Variational Barycentric Coordinates
DESCRIPTION:Ana Dodik (MIT CSAIL); Oded Stein (University of Southern Cali
 fornia, MIT CSAIL); and Vincent SItzmann and Justin Solomon (MIT CSAIL)\n\
 nWe propose a variational technique to optimize for generalized barycentri
 c coordinates that offers additional artistic control compared to existing
  models. Prior work represents barycentric coordinates using meshes or clo
 sed-form formulae, in practice limiting the choice of objective function. 
 In contrast, we directly parameterize the continuous function that maps an
 y coordinate in a polytope's interior to its barycentric coordinates using
  a neural field. This formulation is enabled by our theoretical characteri
 zation of barycentric coordinates, which allows us to construct neural fie
 lds that parameterize the entire function class of valid coordinates. We d
 emonstrate the flexibility of our model using a variety of objective funct
 ions, including multiple smoothness and deformation-aware energies; as a s
 ide contribution, we also present mathematically-justified means of measur
 ing and minimizing objectives like total variation on discontinuous neural
  fields. We offer a practical acceleration strategy, present a thorough va
 lidation of our algorithm, and demonstrate several applications.\n\nRegist
