## Detailed Description

template<size_t Order, bool Staggered = false>
struct openvdb::v11_0::tools::Sampler< Order, Staggered >

Provises a unified interface for sampling, i.e. interpolation.

Order = 0: closest point Order = 1: tri-linear Order = 2: tri-quadratic Staggered: Set to true for MAC grids
