3D animation is the art of creating computer-generated imagery (CGI) that can be manipulated and animated in a three-dimensional space. It involves the use of sophisticated software to create digital models of characters, objects, and environments, which can then be brought to life with fluid movements and realistic textures. 

3D animation is widely used in film, video games, advertising, and other industries where visual storytelling is essential. As a 3D animator, you’ll need a powerful computer with high-end graphics capabilities, as well as industry-standard software such as Autodesk Maya, Maxon Cinema 4D, or Blender. You may also need additional equipment such as a graphics tablet, a 3D printer, or motion capture technology depending on desired output.

There are various career paths available in the 3D animation industry, including positions such as 3D modeler, character animator, lighting artist, and visual effects supervisor. You can work in a variety of settings, including animation studios, game development companies, advertising agencies, and film production houses. It’s also possible to work as a freelancer and collaborate with clients from around the world.
