Warping and Morphing Images
•
Displaced Target Shapes: These are not shapes you either create or modify directly.
Instead, they’re indicators that show the amount of displacement in that region of
the image, based on either the overallDisplacement parameter, or that shape’s
Displacement parameter if it is being animated independently. These shapes are
designed to help you see what the deformation will be without having to render the
entire image. Displaced target shapes are pink by default.
Note: The colors of each control shape type can be modified in the shapeColors
subtree of the colors subtree of the Globals tab.
For information on drawing shapes in the Warper and Morpher nodes, see “
Source shapes and target shapes may be drawn separately, or you can duplicate the
source shape you create and modify it to quickly create a target shape. It’s not
necessary for the source and target shapes to have the same number of points, since
the actual path that an animated deformation will follow runs along the connection
lines that appear once you connect a source shape to a target shape.
Controlling a Warp Effect Using Several Shapes
In both the Warper and Morpher nodes, you may create as many source/target shape
pairs as necessary to deform various parts of the subject. Unlike the RotoShape node,
which only allows for the creation of closed shapes, the Warper and Morpher nodes
allow you to create closed shapes, open-ended shapes, and single-point shapes. This
flexibility allows you to create any kind of deformation you need.
