The technology we will discuss is CGI or Computer Generated Imagery in films. The web browser renders the document received from the webserver.Isn’t it easy to get convinced by the stunning visuals on the big screen? Aren’t the alien beings in Avatar or the sandworm in Dune real enough to awaken the audience? Well, it is pretty much real or created to look natural by experts sitting behind computer screens.The Web server adds a MIME header and sends the HTML text to the Web browser. The gateway program processes the information and returns HTML text to the Web server.From the URL, the Web server decides that it should activate the gateway program listed in the URL and send any parameters passed via the URL to that program.The client sends an HTTP request through a URL.The steps involved in creating a dynamic HTML document on the fly through CGI are as follows: The steps involved in creating a dynamic HTML document on the fly through CGI are as follows: Thus, CGI works as a gateway between the AOL server and the program you write. Depending on the type of request from the browser, the web server may provide a document from its own document directory or executes a CGI program which means it passes the input from the reader (browser) to the program and output from the program back to the reader (browser). The browser runs on a client machine exchanges information with a Web server using the HyperText Transfer Protocol or HTTP. The browser sends a URL that causes the AOL server to use CGI to run a program. CGI applications can be written in any programming language, some of which are Perl, PHP, and Python. Generally, CGI programs are used to generate pages dynamically or to perform some other action when someone fills out an HTML form and clicks the submit button. However, any program that can run on a web server is usable as a CGI script. In general, it means taking an HTTP request and passing it to an application in order to deliver a dynamically generated HTML page back to a browser. So, it is an interface for running executable via a web server. ![]() CGI can also be described as a set of standards or rules where a program or script can send data back to the webserver where it can be processed. It is the best way for a web server to send forms and connect to programs on the server. It is a technology that enables a web browser to submit forms and connect to programs over a web server. (ii) CGI: Common Gateway InterfaceĬGI stands for Common Gateway Interface. There are many other movies which made good use of CGI such as Avatar, Lord of the Rings, Inception, Finding Nemo, The Matrix, and more. After few years, it was used in a movie "Star Wars." In 1993, it was used in the movie "Jurassic Park". ![]() The CGI was used for the first in a movie in 1973 Michael Crichton's "Westworld". In this case, the lighting on the graphics must match the lighting from the scene to make the finished product seamless. In live-action films the graphics are mixed with the previously filmed scenes. These adjustments make animation look real and not cartoonish. How CGI Works:įirst, the artists create computer-generated graphics and then to make graphics look real the texture, lighting and color are adjusted. The quality of the visual effects produced by CGI is higher and controllable as compared to physical ones such as creating miniatures for shots, hiring extras for crowd scenes, etc. These features can be modified as per the requirement of the image, and video in order to make them look real. The features like reflection, illumination can be assigned to the wireframes. ![]() A single artist can produce content with CGI without using actors, set pieces or props.ĬGI is created with the help of wireframe models. As CGI visuals are cost-effective than traditional photographic ones, they are widely used throughout the world. This technique manipulates the environment and creates photorealistic images for the print and electronic media such as movies, videos, games, etc. In short, it allows you create characters and motion that look real and which may not be created using other methods. It is an application of computer graphics (imaging software) which is used to create realistic-looking (three-dimensional) images, still and animated visual content, anatomical modeling, architectural design, video game art, special effects in movies and electronic media, etc. ![]() What is the full form of CGI (i) CGI: Computer Generated ImageryĬGI stands for Computer Generated Imagery.
