Animation; The term gives an instant idea of cartoons and movies based on computer graphics, but before this there was a technique called the phenakistoscope that had simple pictures that moved simultaneously giving the effect of animation. There were several animated features created using these drawings that differed from the previous one. This method disappeared at the end of the 21st century and the drawings were scanned or drawn directly on computers. Computer animation is the rapid display of a sequence of images of 2-D or 3-D illustrations or positions of models to create an illusion of movement. The 3D animations give the impression of looking at the characters from all angles just like in real life. It can be grouped in several terms:
Shaded cell animation:
It is also called cell shading or toon shading, which is designed to make computer graphics appear hand-drawn. It is used to copy the style of a comic or cartoon characters.
Morph target animation
It is stored as a series of vertex positions. At each keyframe in the animation, the vertex will move to a different position. This can be used to enliven clothing, skin, and facial expressions.
Skeleton animation
This is also known as rigging and is a technique for vertebrates. This technique works by building a series of bones and each bone is associated with a part of the visual representation of the characters.
Motion capture
It is a procedure to digitally record action movements. It can be used in video games to animate game characters and in film making it refers to the technique of recording the action of human actors.
Crowd simulation
It is the process of reproducing the movement of a large number of objects or characters and is used when there are more characters than can be animated using the other methods.
Industries that are using 3D animations are interior design, medical visualizations, naval architecture, and corporate presentations. There are several interactive 3D animation programs that allow you to visualize and redesign a room. These are used by architectures to design homes for their clients. This can be used in medical field training to explain various surgical concepts, phenomena, and techniques to give academics a better and clearer view. Then in the naval field it is used in ship design by making a 3D ship model which helps in the rapid progress of ship building projects. Also in the business world it is used to prepare impressive presentations and interactive websites.
3D animations are very realistic and are used to give special effects in movies. The film and advertising sectors offer ample opportunities for the growth of the animation industry. Computer and software jobs have accelerated the pace of the animation industry. The growth of its use in the gaming industry has made it a dynamic and rapidly growing field. To provide a detailed product description, we now no longer rely on still images, 3D animation is the answer to create an interactive environment where a person can interact with objects and enjoy the virtual world created around them. We can say that with its diversity and effectiveness, it has not left any field untouched by its impact.
