SUMMARY:ART-Owen Scrambling
DESCRIPTION:Technical Papers\n\nAbdalla G. M. Ahmed (KAUST), Matt Pharr (N
 VIDIA), and Peter Wonka (KAUST)\n\nWe present a novel algorithm for implem
 enting Owen-scrambling, combining the generation and distribution of the s
 crambling bits in a single self-contained compact process.\nWe employ a co
 ntext-free grammar to build a binary tree of symbols, and equip each symbo
 l with a scrambling code that affects all descendant nodes.\nWe nominate t
 he grammar of adaptive regular tiles (ART) derived from the repetition-avo
 iding Thue-Morse word, and we discuss its potential advantages and shortco
 mings.\nOur algorithm has many advantages, including random access to samp
 les, fixed time complexity, GPU friendliness, and scalability to any memor
 y budget.\nFurther, it provides two unique features over known methods: it
  admits optimization, and it is invertable, enabling screen-space scrambli
 ng of the high-dimensional Sobol sampler.\n\nRegistration Category: Full A
