Metamorphosis means to change shapeappearance or form.

What is morphing?

Morphing can be defined as:

- Transition from one object to another.

- Process of transforming one image into

another.

An animation technique that allows you to

blend two still images, creating a sequence of

in – between pictures that when played in

Quick Time, metamorphoses the first image

into the second.

Steps Involved:

• The morph process consists of :-

1) Warping two images so that they have the same

“shape’’.

2) Cross dissolving the resulting images .

W RPING

• A warp is a 2-D geometric transformationand generates a distorted image when it isapplied to an image.

• Warping an image means : apply a givendeformation to it.

• Two ways to warp an image:- Forward mapping. Reverse mapping.

Forward Mapping

• Each pixel in source image is mapped to anappropriate

pixel in destination image.

• Some pixels in the destination image may

not be mapped.


11/24

Reverse Mapping

• This method goes through each pixel in thedestination image and samples an appropriate

source image pixel.

• All destination image pixels are mapped to

some source image pixel.

• This mapping is used in the Beier/Neely linemorphing method.

Morphing Process

• Step I : Interpolating the lines: Interpolate the coordinates of the end pointsof every pair of lines.

•

Step II : Warping the Images Each of the source images has to be deformed

towards the needed frame.

The deformation works pixel by pixel is basedon the reverse mapping. This algorithm is calledBeier-Neely Algorithm.

Morphing Effect in Flash

Macromedia Flash is known as one of the greatest animation tools around. Using the

Flash authoring tool you can create:

• Frame-by-frame Animations• Motion Tweened Animation• Morphing Animation


18/24

Frame by frame animation


19/24

motion-tweened animations which are

created by specifying the first and the

last frames only, and dynamic

animations that are generated via

Action Script.

Motion Tween animation


21/24

In morphing animations which you specifythe first and the final shapes so that all the

frames in between are created by the

authoring tool. This is called Shape Tween.
