CGI (Computer-Generated Imagery) refers to the creation of 2D or 3D digital images, animations, and visual effects using computer software. It is widely used in films, television, video games, advertising, virtual reality, architecture, and engineering.
Applications of CGI in Filmmaking

- Environments & Worlds – Helps build realistic and fantasy landscapes that would be impossible or expensive to film.
- Special Effects (VFX) – Explosions, fire, water, weather, and supernatural effects.
- Motion Capture (MoCap) – Capturing real-life movements and converting them into CGI characters (e.g., Gollum in The Lord of the Rings).
