Detailed Description

template<typename GridT, typename RealT = typename GridT::ValueType>
class nanovdb::WenoStencil< GridT, RealT >

This is a special 19-point stencil that supports optimal fifth-order WENO upwinding, second-order central differencing, Laplacian, and zero-crossing test.

Note: For optimal random access performance this class includes its own grid accessor.
