SUMMARY:High-Order Directional Fields
DESCRIPTION:Technical Papers\n\nHigh-Order Directional Fields\n\nBoksebeld
, Vaxman\n\nWe introduce a framework for representing face-based direction
al fields of an arbitrary piecewise-polynomial order. Our framework is bas
ed on a primal-dual decomposition of fields, where the exact component of
a field is the gradient of piecewise-polynomial conforming function, and t
he coexact component is defined as the adjoint of a dimensionally-consiste
nt discrete curl operator. Our novel formulation sidesteps the difficult p
roblem of constructing high-order non-conforming function spaces, and make
s it simple to harness the flexibility of higher-order finite elements for
directional-field processing. Our representation is structure-preserving,
and draws on principles from finite-element exterior calculus. We demonst
rate its benefits for applications such as Helmholtz-Hodge decomposition,
smooth PolyVector fields, the vector heat method, and seamless parameteriz
ation.\n\nRegistration Category: FULL ACCESS, EXPERIENCE PLUS ACCESS, EXPE
