Morphing

What is it?

Morphing (Shape Tweening) is the second type of Flash tweening. If compare to motion tweening, morphing is more versatile. If motion tweening is used to change only some properties of the symbol, such as size, position, transparency and partially colour, morphing allows to change the shape of the drawing.

If motion tweening can “squeeze” the circle and make it look as an oval, morphing is able to transfer circle into rectangle. Tweening makes the process of transferring gradual and smooth .

Look at this simplest example of morphing. Touch the green circle and observe how the circle change it’s shape to the rectangle. If you move the mouse cursor out – rectangle again becomes a circle.

Morphing like motion tweening lets Flash engine to calculate a series of intermediate shapes between keyframes and makes transition from shape to shape look gradual and "effortles"
