• 2D/Traditional animation

• •Traditional animationbegan with each frame being painted and then filmed.

• •Cell animation, developed by Bray and Hurdin the 1910s, sped up the process by using transparent overlays so that characters could be moved without the need to repaint the background for every frame

• 2D/Traditional animation

• •The "classic" form of animation, the "animated cartoon", as developed in the early 1900s

• •refined by Ub Iwerks, Walt Disneyand others

• •requires 24 distinct drawings for one second of animation.

• 2D animation• •For 2D animations, separate objects

(illustrations) and separate transparent layersare used. Then the objects are moved by the animator on key frames.

• •The differences in appearance between key frames are automatically calculated by the computer in a process known astweening or morphing. Finally, the animation is rendered.

• 3D/Computer animation

• •Computer generated imagery(CGI)

• •Computer animation involves modelling, motion generation, followed by the addition of surfacesand then rendering.

• 3D/Computer animation

• •It is the recent developments in rendering complex surfaces like fur and clothingtexturesthat have enabled stunningly life-like animation

• 3D Animation

• •All frames must be rendered after modelingiscomplete.

• •For pre-recorded presentations, the rendered frames are transferred to a different format or medium such as film or digital video.

• •The frames may also be rendered in real time as they are presented to the end-user audience.

• Animation Process

• •Pre-production

• •Production

• •Post-production

• Traditional Animation Process

• · Script or story development·Storyboard· Record a soundtrack· Produce a detailed layout of the action.· Correlatethe layout with the soundtrack.· create "keyframes” · add "in-betweening“

• Traditional Animation Process• · pencil test· Transfer the pencil test frames to

sheets of acetate film, called "cells". · The cells are then assembled into a sequence and filmed
