2D and 3D animation
In simple words, 2D means two dimensional. By using this technology, image can be seen from two dimensions only. 3D refers to three dimensions, by the help of which, an image can be viewed from three dimensions. To understand it in a better manner, we can say, 2D refers to a square drawn on a piece of paper where only the length and breadth of it can be seen while a cube is an example of 3D figure which shows its length, breadth as well as height. In other words, "the creation, display and manipulation of objects on computer in two dimensions" is called 2D. Here, objects can be seen when constructed from two dimensions only (height and width, rows and columns, etc.).

Another drawback was that the details of movement could not be drawn. Also, this process was very tedious. The artist had to hand draw the scene character numerous times and he could not afford to be inconsistent even to a small degree. But, now these sketches are made on computer thereby enabling the artist to make drawings in an effortless manner. After the structuring of models, they are textured, titled and finally animated as per requirement of the story. And then, animation is rendered or processed as a picture (or frames) which are coupled with the audio and final product is ready.

Use of modern animation techniques have widened up its scope. Now, animation is not confined to movies. It has entered the numerous fields where opportunities for upcoming animators are likely to grow up exponentially.

To meet the demand of industry, more than 20,000 job opportunities are waiting to come up in the next three years. Wide application of animation, right from the movies, entertainment to education and other areas like TV, business, product promotion, websites, architecture and virtual reality has contributed a lot to its growth.
