CGI FULL FORM
CGI stands for Computer Generated Imagery. It is a computer graphics application (imaging software) used to create realistic-looking (three-dimensional) images, still and animated visual content, anatomical modeling, architectural design, video game art, special effects in film and electronic media, etc. It allows you to create characters and movements that look real and cannot be created using other methods.
This technique manipulates the environment and creates photo-realistic images for print and electronic media such as movies, videos, games, etc. Since CGI images are affordable compared to traditional photographic images, they are widely used around the world. A single artist can produce CGI content without using actors, sets, or props.
The CGI is created using wireframe models. Functions such as reflection, lighting can be assigned to wireframes. These features can be changed according to the requirements of the image and video to make them look real. The quality of visual effects produced by CGI is superior and controllable to physical effects, such as creating thumbnails for shots, hiring extras for crowd scenes, etc.
CGI also stands for Common Gateway Interface. It is a technology that allows a web browser to submit forms and connect to programs through a web server. It is the best way for a web server to submit forms and connect to programs on the server. CGI can also be described as a set of standards or rules in which a program or script can send data to the webserver where it can be processed.
HOW CGI (COMPUTER GENERATED IMAGERY) WORKS?
First, artists create computer-generated images, and to make the images look real, the texture, lighting, and color are adjusted. These modifications make the animation look real and not cartoonish. In live-action movies, the graphics are mixed with previously shot scenes. In this case, the lighting on the artwork must match the lighting of the scene to make the finished product seamless.
CGI was first used in the film in 1973; "The West World" by Michael Crichton. A few years later, it was also used in "Star Wars" movies. It was also used in the movie "Jurassic Park" in 1993. Many other movies have made good use of CGI such as Avatar, The Lord of the Rings, The Matrix, and others.
HOW CGI (COMMON GATEWAY INTERFACE) WORKS?
The browser sends the URL that asks the AOL server to use the CGI program. The browser runs on a client computer and exchanges information with a web server using the HyperText Transfer Protocol or HTTP. Depending on the type of browser request, the webserver can either serve a document from its document directory or run a CGI program, meaning it passes input from the reader (browser) to the program and the program's output to the reader (browser). Therefore, CGI acts as a gateway between the AOL server and the program you are writing.
FEATURES OF COMMON GATEWAY INTERFACE
1.CGI is well described and supported.
2.Scripts are generally described in C, Perl, or maybe even in simple shellcode.
3.It is a technique that enables HTML to an interface.
4.CGI is the best way to create a counter as it is currently the fastest.
USES OF CGI (COMPUTER-GENERATED IMAGERY)
1.CGI is used in movies, TV shows, and commercials, and print media.
2.Video games typically use real-time computer graphics (rarely called CGI), but may also include pre-rendered "cutscenes" and introductory movies that would be typical CGI applications.
3.CGI is used for visual effects because the quality is often higher and the effects are more manageable than other more physics-based processes, such as building thumbnails for effect shots or hiring extras for crowd scenes, and because it enables the creation of images that would not be possible with any other technology.
4.It can also enable a single artist to produce content without the use of actors, expensive sets, or props.
5.The recent accessibility of CGI software and the increased speed of computers have enabled individual artists and small businesses to produce professional movies, games, and artwork from their home computers.
