Warp

The Grid Editor | Tools | Warp command in the grid editor enables the Warp tool mode. Use the Warp tool mode to drag grid values and "sculpt" the grid. Click the Grid Editor | Tools | Warp command to start warp mode. The cursor changes to a crosshair with a circle to visually indicate the Brush size . The Warp command button is highlighted in yellow to indicate warp mode as well.

 

Click and drag to pull grid values in the direction that you drag the cursor. The grid Nodes, Labels, Color Fill, and Contours update automatically as you use the Warp command.

 

Press ESC or click another Grid Editor | Tools command to end Warp mode.

 

NoData Nodes and Warp

When dragging from a region with data into a NoData region, the NoData values are replaced by values from neighboring nodes. The Warp tool can be used to remove NoData regions from the grid. However, NoData values are not dragged out from NoData regions by the warp tool. If you wish to assign the NoData value to nodes, use the Eraser.

 

Tool Options

The Brush size, Density, and Pressure control how the Warp tool drags and changes the grid vales.

 

Brush Size

The Brush size tool option controls the diameter of the tool. The Brush size specifies the diameter in number of grid cells in the X direction. The Brush size setting is located in the tools options bar at the top of the grid editor window. There are three methods for changing the Brush size:

The cursor circle increases or decreases size with the Brush size setting and zoom level. The Brush size setting is saved and persistent across multiple grid editor windows.

 

A Brush size of 1 makes the diameter of the brush equal to the horizontal spacing of one grid cell.

A Brush size of 3 makes the diameter of the brush equal to the horizontal spacing of three grid cells.

 

Density

The Density tool option controls the weighting of the tool effect radially from the center of the brush. The cursor location (where the crosshair is located) receives the maximum effect of the selected tool mode. The Density setting is located in the tools options bar at the top of the grid editor window. There are two methods for changing the Density:

The Density setting can be any value between 1 and 100. A Density setting of 1 has maximum "feathering" or blending between the center of the brush and values just outside the brush. A Density setting of 100 applies the tool mode effect to all nodes within the brush equally. The Density setting is saved and persistent across multiple grid editor windows. The default Density setting is 25.

 

These line plots show how Density affects the weighting of the tool mode effect

(y-axis) as distance from the center of the brush increases (x-axis)

 

Pressure

The Pressure tool option controls the speed at which tool effects are applied as the brush moves. The Pressure setting is located in the tools options bar at the top of the grid editor window. There are two methods for changing the Pressure:

The Pressure setting can be any value between 1 and 100. A Pressure setting of 1 applies the tool effect the minimum amount with each click or drag. A Pressure setting of 100 applies the tool effect the maximum amount with each click or drag. The Pressure setting is saved and persistent across multiple grid editor windows. The default Pressure setting is 25.
