Detailed Description

template<typename ExecSpace, int ORDER = 2>
class axom::quest::NURBSCurveGWNQuery< ExecSpace, ORDER >

Preprocesses NURBSCurve geometry for GWN evaluation, and performs the calculation on the DOFs of an input MFEM mesh.

Template Parameters

ExecSpace	The execution space for the algorithm.
ORDER	If agglomeration is used, this is the order of the Taylor expansion.

Possible evaluation modes are use_direct_eval : If true, evaluation is done curve-by-curve. If false, evaluation is sped up with agglomeration via Taylor-expansion use_memoization : Caches and re-uses subdivision data for curve evaluations
