- Frame-by-frame figure animations, separate objects (illustrations and graphics) and separate transparent layers are used
- The differences in appearance between key frames are automatically calculated by the computer. (tweening)
- For output the animation is rendered or compiled.
- Types of animation
- Cel animation. Images painted on celuloid overlays, filmed in sequence
- Keyframe - Create a series of model frames, then let computer extrapolate between them
- Tweening - The process of extrapolating motion, color, size, etc. between keyframes.
- Kinematics (inverse kinematics) - Animation that is based on the movement of the human body - example
- Study of movement and motion of bodies that have joints
- Requires a calculation of position, rotation, velocity and acceleration of all parts
- Objects can be linked (Parent/Child )
- Morphing - Transition between designated regions on two images (Identifying points of congruence between two images) - example | Morpheus
- Rotoscoping - each frame is an image state (live action movement, frame by frame) - example
