What is Computer Animation?
Computer animation refers to any sequence of visual changes in a scene, i.e it is a series of images that are displayed in a sequence. In addition to changing object position with translations or rotations, a computer-generated animation cloud display variations in object size,color,transparency or surface texture. Advertising animations often transition one object shape into another. For example, transforming a can of motor oil into an automobile engine. Computer animation can also be generated by changing camera parameters such as position orientation and focal length. We can also produce computer animation by changing lighting effects.
Applications areas of Computer Animation are entertainment ( motion pictures and cartoons),advertising,scientific and engineering studies etc.
There are mainly 2 types of animation:
a) 2D Animation: 2D animation also known as cell(pixel based) animation is the most common kind of animation, where flat images ( a rectangular blocks of pixels) are drawn one frame at a time. The animation package also involves some special effects like morphing and warping.
b) 3D Animation: In 3D animation, mathematical model of 3D object is created to describe realistically in depth. Now it has become a common media element in film , video and multimedia packages.
Animation in Film-making:
* Difficult scenes, which are unable to do, are now done from computer as real and amazing. i.e jumping from tall building or mountain, flying man and women, ghost film, etc.
* Cartoons can be made from animation with funny faces like making noses bigger with big head and thin legs.
* Duplicate of a man can be made ; which copies its characters.
