Button Lock Shapes Select Display Image Description These three buttons lock all source, target, and boundary shapes in the Viewer, preventing them from being edited. Each control locks all shapes of that type in the Viewer. Individual shapes may be locked using controls in the Parameters tab. However, the Shape Lock buttons in the Viewer shelf supersede the Lock buttons in the Parameters tab. The Source/Warped Image pop-up menu allows you to toggle the Viewer's display between the unmodified and modified images. You may quickly jump between views by pressing: • F9 to view the original source image • F10 to view the original target image (Morpher only) • F11 to view the warped image Drawing and Editing Shapes The biggest difference between drawing shapes with the RotoShape node and with the Warper and Morpher nodes is that while RotoShape allows you to draw only closed shapes, the Warper and Morpher nodes allow you to create not only closed shapes, but also open shapes and single-point shapes. Open shapes make it very simple to define deformations for visual features like eyebrows, muscle outlines, and other contours that don't require a closed outline. Single-point shapes allow you to define deformations for small image details, and are also very effective as boundary shapes you can use to pin down parts of the image you don't want to be affected by nearby source/target shape pairs. The Warper and Morpher nodes both warp the image using the same shape controls, and the methods used to create and edit shapes in each node are identical. Drawing New Shapes Drawing new shapes works the same whether you're creating a source, target, or boundary shape. In each case, you create a new, unassigned shape first, and then assign its type in a subsequent step. Unassigned shapes appear yellow, by default. To create a new unassigned shape: 1 Click the right side of a Warper or Morpher node to load its parameters into the Parameters tab, and its controls into the Viewer shelf. 2 In the Viewer shelf, click the Add Shape button. 3 In the Viewer, begin drawing a shape by clicking anywhere on the image to place a point. 832 Chapter 27 Warping and Morphing Images
