As more and more artists are using computers to create animations, 3D animations are becoming quite popular. Earlier only the artists of a few big companies had access to the software required to create a 3D animation movie. However, today more people are getting access to these software and more companies are using these for various reasons. These days even mobile phones with 3D display screens are being developed.
To understand how 3D animation is created, you will have to understand how 2D animation works. Before the age of computers, artists drew slides with the slightly altered images and then displayed the series of slides one after another. For example, if the artist wanted to show a ball falling; then they would draw the ball a little lower in the second slide, and even lower in the third slide and so one. When the slides were presented at a certain speed, the illusion of the moving ball was created.
The problem with this method was that was time consuming and tedious. Soon the time required for the creation of the frames was reduced because the computers could be programmed to create the frames between the initial and final positions of objects. The artist would have to only make correction if required or add other elements to the frames. The option of the copy paste function also ensured that much of the work could be done quickly.
However, the motion pictures created using the 2D techniques were not really up to the mark because they these did not look realistic enough. 3D animation made it possible for the movies to look more natural and thus this technology has been adopted in spite of the fact that it is more difficult to make such a movie.
The first step in 3D animation is character sketching. The artist sketches images of the characters from as many angles as possible so that the character modeler can create the 3D model. Then the character modeler chooses from a variety of methods to sculpt the model pretty much in the same way a sculptor uses clay or stone to make a real sculpture. The only difference is that this done on a virtual platform.
After this, the scene is built and the characters are set into motion by the animator who uses software to create the illusion of movement by giving the initial and final positions of the desired movements.
Since this creates a more lifelike movie, people like to watch it. Naturally, it is becoming one of the most popular modes of movie making.
