2D animation and 3D animation are two different kinds of animation, each has its own advantages, of course, each has its own shortcomings. Some people believe that 3D animation is certainly better than the 2D animation. In fact, this statement is incorrect. Here, we will learn some basic 2D animation and 3D animation, and some of the main 2D animation and 3D animation tools.
What is a 2D animation?
There is a story like this: a computer company's staff visited a computer goods exhibition, he walked into a manufacturer's booth, whose 2D animation software is well done, but the computer staff seriously asked the software maker: "Is your software 2D? If I can get 3D, why I use 2D?"
There are many answers to this question. Like video and film, 2D animation on the Web is much more than 3D animation. 2D animation of the richness of the heritage of artists of genius and the genius cartoon character accumulated over 80 years. By comparison, the 3D animation only by desktop computer users for about 10 years, there are hundreds of cell animation feature films, short films and long cartoons thousands. So you don't need to convert 2D to 3D deliberately.
A comparison of 2D and 3D
3D is not necessarily better than 2D, but a some fresh, they attract the attention of many software developers, these people are kind of the charm of the Hollywood-style special effects attracted. There is no doubt that the art of 3D animation is not yet fully developed, the vast majority of users, it is just a science instead of art. Compared with the 3D animation, cell animation easy to understand, in many ways easier to accomplish, but in fact, it relies on the talents of the artist's grasp of traditional painting techniques, and rarely relied on the computer.
However, 2D animation is not the Middle Ages in Europe to develop not just a sketch school students set up. It includes the art of composition similar to the unit animation respectable and familiar, but it also includes modern, sometimes surreal things, the synthesis of digital timeline, rotation, transitions and special effects, has become a television and animation the main pillars of the film, is also a pillar of the Web. Digital video editing tool itself is a powerful animation tools, 2D computer animation technology allows only basic graphic design techniques to do the animation is also easy.
Even in the animation studio such as Disney have a longer history, the computer is now the scene of an important part of almost filmmaking each step should be used, and 3D artists in any case must at the same time master digital 2D animation tool, the fact, is an artist of 3D movies or TV image into a 2D animation tools and technology portfolio, so that it can form a scene. For example, in the movie "Titanic", the magic of movie special effects is the use of 3D animation, these 3D animation is the use of the synthesis of 2D animation tool for vivid 2D movies, making it look very realistic. But for some people, they may feel uncomfortable for watching 3D movies, so it is need to covert 3D to 2D video.

In this regard, it makes the unit animation art and digital synthesis technology combine to become more meaningful. Unit animators might say they are not a computer artist, and computer animation designers will argue that they are not cell animation designer, but learn from each other in modern society, each discipline, the best animators as the translator between the digital and analog data modem, be able to understand two aspects of the use of technology, along the two directions of processing pictures.
Although some of the tools mentioned here are the high-end professional tools used for animation and film design, but in fact any tool for video and film services can also be used in Web animation, but you might want to right ratio, timing and image quality for adjustment and coordination, tools and techniques do not have to be changed.
