Warping and Morphing Images

Using this formula yields the following memory usage table:

If you don’t have enough RAM to handle the resolution you’re working at, switch the
maxThread parameter (in the renderControls subtree of the Globals tab) to 1. This
reduces the memory requirements for this operation.

Using Shapes to Warp and Morph

Both the Warper and Morpher nodes allow you to use animated shapes to control and
animate the deformation of an image. Both nodes work using four types of shapes that
you draw. These shapes work together to define which parts of an image will be
deformed to fit into shapes that you define.

Types of Control Shapes

The following simple example clearly shows the different shapes used to create a warp
effect used to bend the thumb down.
