Accessor for turning iteration over Diff2D into a mesh grid.
The mesh grid concept is adapted from MATLAB. It is a two banded image (i.e. with 2D vector pixel type) whose first band contains the x-coordinates of the current pixel, and whose second band contains the y-coordinates. See meshGrid() for more detailed documentation.
typedef TinyVector<Diff2D::MoveX, 2> value_type |
the value_type of a mesh grid is a 2D vector
value_type operator() | ( | ITERATOR const & | i | ) | const |
read the current data item
value_type operator() | ( | ITERATOR const & | i, |
DIFFERENCE const & | diff ) const |
read the data item at an offset (can be 1D or 2D or higher order difference).
