CGI animation, or computer-generated imagery animation, is the process of using computer software to create moving images. It's a type of visual effect (VFX) that's used in film, television, and video games. 

How it works

• CGI animation uses complex algorithms to generate images. 
• It can be used to create 2D or 3D images. 
• CGI animation can be used to create dynamic characters, detailed environments, and special effects. 
• CGI animation can be used to simulate lighting, physics, and interactions. 

Why it's used

• CGI animation is used to create realistic textures and simulations. 
• CGI animation can be used to create scenes that would be too expensive or difficult to build in real life. 
• CGI animation can be used to create fantastical backdrops. 
• CGI animation can be used to alter an actor's appearance.
