SUMMARY:Curl Noise Jittering
DESCRIPTION:Technical Papers\n\nJ. Andreas Bćrentzen and Jeppe Revall Fris
 vad (Technical University of Denmark) and Jonŕs Martínez (INRIA)\n\nWe pro
 pose a method for implicitly generating blue noise point sets. Our method 
 is based on the observations that curl noise vector fields are volume-pres
 erving and that jittering can be construed as moving points along the stre
 amlines of a vector field. We demonstrate that the volume preservation kee
 ps the points well separated when jittered using a curl noise vector field
 . At the same time, the anisotropy that stems from regular lattices is sig
 nificantly reduced by such jittering. In combination, these properties ent
 ail that jittering by curl noise effectively transforms a regular lattice 
 into a point set with blue noise properties. Our implicit method does not 
 require computing the point collection in advance. This makes our techniqu
 e valuable when an arbitrarily large set of points with blue noise propert
 ies is needed. We compare our method to several other methods based on jit
 tering as well as other methods for blue noise point set generation. Final
 ly, we show several applications of curl noise jittering in two and three 
 dimensions.\n\nRegistration Category: Full Access, Enhanced Access, Trade
