As technology has advanced, CGI has become ubiquitous in everything from mid-budget comedies to blockbuster hits to animations. What helps us differentiate between reality and CGI?
One can identify CGI by 4 characteristics that distinguish a realistic-looking object from a fake-looking CGI: albedo, subsurface scattering, displacements, and dynamic alterations. Light sources and location are key predictors because items from various sources may have varying illumination.
Look at where the spotlights fall on curved surfaces and where the shadows point. Examine the sharpness of the shadows.
Let’s find out more about CGI below!
What Is Considered CGI?
CGI has its roots in the 1950s, when mechanical computers were utilized to draw patterns on cel animation, which were later used in feature films. What really is CGI?
CGI, or computer-generated imagery, is a phrase used to describe digitally manufactured pictures in movies and on television. CGI is a subset of visual effects (VFX), which are images created or manipulated by filmmakers that do not exist in the real world being shot on film or video.
Different methods can be used to create CGI; some are listed below.
- Algorithms may be used to generate complicated fractal patterns.
- Vector forms are created in 2D pixel-based picture editors.
- From simple primitive shapes to complicated formations made of flat triangles and quadrangles, 3D graphics software can produce it all.
To create CGI, designers first create the graphics. They do this by paying meticulous attention to elements such as texture and lighting. They then insert them into the film. If they do their job correctly, CGI will blend in seamlessly with the film.

Is CGI Cheaper Than Animation?
CGI is significantly less costly and faster to create than traditional animation. It was this that brought them to the attention of professionals in advertising, gaming, and other industries. As a result, the experts were able to deliver their work far more quickly than they could have with traditional means.

Why Is Modern CGI Worse Now?
When analyzing items in an animation or a video, you may frequently notice anomalies in the details. Some media sources have the worst CGIs, and why is that?
One of the primary reasons CGI outperformed approaches such as stop-motion animation was movement. The physics was precise, the details calculated. Today, with CGI, Hollywood has lost the sense of realistic movement after more than 20 years.
Scenes from films such as the Matrix Reloaded and Cat Woman demonstrate stunts that would be impossible to achieve with a real human in the modern industry.
Computer graphics is a highly technical art that requires hundreds, if not thousands, of highly trained artists. The issue is that as CGI in movies progresses, so does the audience.
Conclusion
Alfred Hitchcock’s Vertigo was the first film to incorporate CGI in 1958, and it has been used in various digital mediums ever since.
One can differentiate a CGI object by looking for shadows and the reflection of light from the surface of these objects.
