It uses interpolation to determine the values of selected portions of the grid from areas outside the selection. There are three ways to select the set of grid points to edit. As the tools are passed over portions of the grid, the data values are immediately modified. The Bulldozer smooths gradients that it passes over. Since all of the editors for a worksheet share the same database, changes made on the spatial editor will immediately be shown on all other spatial and temporal editors connected to the same worksheet.
Vector fields show their direction component with wind barbs or arrows.
The temporal editor also provides an active sample display which continuously shows the value of the data points as the mouse is moved. An edit tool allows the user to adjust the color rectangle or time line until the desired value is shown. The changes made on the temporal editor are propagated back to the spatial grid. The user may select one of three influence methods in applying the changes to the spatial grid. The single-point method changes only the single grid point for which the temporal editor represents.
