Yes, 3D animation is often referred to as CGI (Computer-Generated Imagery). CGI encompasses a wide range of digital techniques and technologies used to create visual elements in films, video games, advertisements, and various forms of media. 3D animation is a subset of CGI and involves the creation of animated scenes, characters, and objects in a three-dimensional digital environment.
In 3D animation, artists use specialized software to model, texture, rig, and animate objects and characters within a virtual 3D space. This process allows for the creation of lifelike and dynamic animations, as well as the manipulation of camera angles and perspectives. The result is often highly realistic and visually impressive animations that can be integrated seamlessly into live-action footage or used to create entirely digital environments.
So, when people refer to 3D animation, they are typically talking about a form of CGI that involves the use of digital tools and technology to generate animated content in a three-dimensional space.
