But then, that's just what it is, though the grid points are real machines collecting data.

But it still misses many processes that happen between grid points - cloud formation, for example.

One can consider a rectangular grid on the box and sample the function at the grid points.

This procedure is repeated at each grid point.

Case punched to within four grid points of the cube.

Case punched again, once; they jumped forward by a single grid point.

It is used to write finite difference approximations to derivatives at grid points.

The group has tried anything from one grid point to 2000 and is current working on roughly 200 to 300.

Using this grid, the function values are calculated at each grid point.

Here, the resolution is higher (i.e., the grid points are closer together).
