A computer-animated film commonly refers to feature films that have been computer-animated to appear three dimensional on a movie screen. While traditional 2D animated films are now done primarily on computers, the technique to render realistic 3D computer graphics (CG), or 3D Computer-generated imagery (CGI), or 3D rendering is unique to using computers to create movies.

3D rendering is the 3D computer graphics process of automatically converting 3D wire frame models into 2D images with 3D photorealistic effects on a computer. To know more about Animation Rendering please visit 3D Engineering Animation Rendering UK USA.

Computer-animated films typically have two production companies associated with them: an animation studio and a distribution company. For example, Pixar designs and animates their features and Walt Disney Pictures distributes them.
