Graphics:

Graphics are visual presentations on some surface,

such as a wall, canvas, computer screen, paper, etc…

E.g.: photographs, drawings, graphs, diagrams, geometric designs, maps, engineering drawings, or other images.

Computer Graphics:

Computer graphics is a sub-field of computer science and is concerned with digitally synthesizing and manipulating visual content.

The image generation and processing using some techniques in the computer.

Raster Graphics Vector Graphics A raster graphic is an image made of hundreds (or thousands or millions) of tiny squares of color information, referred to as either pixels or dots.

A vector graphic uses math to draw shapes using points, lines and curves.

Animation:

A transformation is involved.

Derived from the Japanese word anime.

Computer Animation

Computer animation is the art of creating moving images via the use of computers .

Dimension

To measure/ measurement.

Measurement required to define the characteristics of an object—i.e., length, width/breadth, and height/depth.

One Dimension

Measurement of an object in only one direction E.g. A one-dimensional object is a single line. It has length but no width or height/depth

Two Dimension

The two dimensional object has any two

of the following:

•Length

•Breadth/width

•Height/depth

Measurement of an object in two directions.

Three Dimensions

Measurement of an object in 3 directions/sides length, breadth, height.

The 3 dimensional object uses length, breadth, height.

Process: Procedure, series of action .

Animation: The word animation means movement of picture.

Get the idea of the story and discuss with others.

Write the idea that you have discussed in the form of a short document.

This document must summarize the main idea of the story.

Make storyboards like the hand-drawn comic book version of the movie and serve as a blueprint for the action and dialogue.

Record the voice for actors.

A reel is a video tape that allows the cleaned-up story board sequence.

The art department creates creates inspirational art illustrating the world of characters (models).

Convert the models that was designed in the story board in to 3-D in the computer using some application.

After the models are made in 3-D, the scenes must be dressed.

Translate the story in to 3-D scenes.

Apply animation on those models.

Models must be shaded using colors.

Lighting completes the look.

Joining all the scenes in to one film.

Add additional effects 1. Sound 2. Actions etc….

Stereograms are 3D images hidden within another picture. In order to view the 3-D images, simply stare at the picture until the image starts to take shape.
