The Grid Ripple node

Rippling

The Grid Ripple node

The Grid Ripple node ripples its input image using a square grid. You can set how it works either in the Drawing Window (see Using the Drawing Window below), or in its XSheet columns:

The Spacing sets the distance between each ripple

The Angle sets the angle at which the distorting grid is placed

The Intensity sets the intensity of rippling: at 0% there is no change, at 100% the image is still recognizable, and at higher values the distortion becomes more extreme

The E/W and N/S values set the center of one of the squares in the grid.

Using the Drawing Window

You can also set the ripple in the Drawing Window:

Display the frame for which you wish to set the position (see Moving between frames).

Select the Grid Ripple node you wish to edit in the Drawing Window; see Selecting nodes in the Drawing Window. The controls appear:

You can now use the controls. As you do so, Director creates any necessary keyframes in the XSheet for you, and sets their values:

To alter the Spacing and/or the Angle, drag the handles on the corner of the square

To set the Intensity, drag the circle; the intensity is 100% when the circle is exactly enclosed by the square

To set the E/W and N/S values, drag the handle at the center of the square.
