| | Compute weight of each surrounding node (or cell-centered nodes) in interpolating a nodal ((or a cell-centered node) field to the given coordinates. If template parameter IdxType is amrex::IndexType::CellIndex::NODE, then the calculations will be done with respect to the nodes. If template parameter IdxType is amrex::IndexType::CellIndex::CELL, then the calculations will be done with respect to the cell-centered nodal. This currently only does linear order. More...
