Creating and Modifying Shapes Many of the shape controls of the Warper and Morpher nodes are identical to those of the RotoShape node, and all share the same methods for creating tangents, closing shapes, inserting and deleting points, and so on. If necessary, you can refer to the RotoShape documentation for more information on creating and modifying shapes. Warper and Morpher Viewer Shelf Controls When a Warper or Morpher node is selected, the following buttons appear in the Viewer shelf. Warp/Morph controls Button Add Shapes Edit Shapes . Description Creates new shapes. Closed shapes are created by clicking the first shape point you created. Open shapes and single-point shapes are created by double-clicking when creating the last point, or by right-clicking in the Viewer, then choosing Finish Shape from the shortcut menu. Allows you to edit shapes. Connect Shapes Clicking this button allows you to create a source/ target shape pair by first clicking the shape you want to be the source, and then clicking a second time the target shape you want to link it to. To define a boundary shape, click this button, then click twice a shape you want to turn into a boundary shape. This effectively makes a single shape into both a source and target shape. Edit Connections Once two shapes have been joined with the Connect Shapes button, the location and angle of each connection line that links source to target shapes may be edited by clicking this button. With this control turned on, select the source or destination point of a connection line. Show/Hide Tangents Toggles the Viewer among showing All shape tangents (the handles that allow you to manipulate Bezier curves), None, or Pick, which only shows the shape tangents of individually selected points. Lock/Unlock Tangents Locks or unlocks all shape tangents in the Viewer. If locked, shape points may still be moved, but the tangents defining the angle of curvature remain locked. 830 Chapter 27 Warping and Morphing Images
