Computer-Generated Imagery, or CGI, is the process of using computer software to create still or animated visual content. CGI is also known as 3D rendering or 3D imaging. CGI stands for computer graphics in three dimensions that are used to create characters, scenes, and other special effects in films, television shows, and video games. Advertising, architecture, engineering, virtual reality, and even art use this technology. In traditional photography, an image is captured using film or a digital camera, whereas computer-generated images are created using the software. CGI is frequently used with three-dimensional (3D) outputs. CGI can, however, produce two-dimensional (2D) effects.
Since its inception, cinema has progressed significantly, particularly in the field of visual effects (visual effects). CGI, or computer-generated imagery, has dominated many films in recent decades, from dramas to blockbusters. The use of CGI effects, while revolutionary, has come under fire in recent years. But what exactly is computer-generated imagery (CGI), what does it entail, and how can it be used to tell more fantastical yet believable stories?
Characteristics of CGI
- Two-dimensional computer-generated imagery, such as text, objects, backgrounds, backdrops, and environments.
- Three-dimensional objects, figures, spaces, and environments.
- In good cases, composite imagery and video trick the eye into believing in the illusion presented.
- In bad cases, obviously fake figures, renderings, objects, and environments that look artificial and/or stand out with regards to everything else.
CGI’s applications
CGI is used almost everywhere because most people believe it can get people’s attention. However, some of the most common applications in which CGI is used are:
- Movies
- Real Estate
- Visual Art
- Video Games
- Engineering
- Marketing
- Advertising
- Television Shows & more
What Can Go Wrong With CGI?
Computer graphics is a highly technical art form that necessitates hundreds, if not thousands, of highly skilled artists. The issue is that as CGI in movies improves, so does the audience’s understanding of it. Audiences become critics and can point out flaws in the CGI team’s work at any point. The good news is that studios have realized that the story, not the CGI, is what matters. Computer graphics should only be used to tell a story, not as the sole reason for making a film.
