CGI Graphics: Redefining a Picture-Perfect World in the Lord of the Rings movie trilogy
The usage of digitally created or manipulated graphics called computer-generated imagery or CGI for short is a technology which has helped not only science but also the arts. In the field of science, CGI has been of great help specifically in the study of medicine. It is being used in creating and studying models for anatomy such as skeletal animation and other imagery for different parts of the body. Additionally, the application of CGI is being used in X-ray Computed Tomography or CT Scan when a number of snapshots or images are put together to produce a three-dimensional representation. In surgery, CGI is also used to create patient-specific surgical plans for example, in knee surgeries. However, it is not only in science and medicine that the CGI technology is being used. In the arts, CGI is used for movies, commercials and other visual imageries. For example, digital manipulation and creation happen in fantasy movies to create or recreate scenery, characters, events and the like. CGI is helpful for movie makers especially when the film calls for sceneries that are either too good to be true or cannot be possibly captured by the camera. Additionally, it is being used for scenes that require a huge number of people such as the armies portrayed in the movie adaptation of The Lord of the Rings. Recreating the scene where armies were marching to Mordor, eventually leading to the movie's climax, using armies of real people would have been impractical. In this case, CGI helped creators portray the scene through digitally manipulating (by multiplying the number of people) images and shots. In the same trilogy, CGI was extremely helpful in the portrayal of the fictional character named Gollum (also named Smeagol), as well as the different Middle Earth “races”. Although an actor portrayed the character Gollum, for example, various facial sensors to capture the emotion of the actor were used, and these digital images along with the aid of CGI technology enabled the movie makers to portray what the author of the book envisioned, despite it being non-existent in this world.
