History of CGI

CGI Development

The first believed use of graphics and animation was the thaumatrope . It was invented in the mid 1820’s by John Paris. The device is a disc with images on both sides of the disc.


Following this, the zoetrope, often known as the “Wheel of Life.” The zoetrope was invented in 1834 by William G Horner. Many people.


In the CGI (computer generated imagery) industry believe that the classic thesis by Sutherland in the early 1960’s was the official beginning of computer graphics and animation, in the form that it is known today.The classic thesis by the pioneer Ivan Sutherland was the beginning of computer graphics which was an interactive computer graphics interface, called Sketchpad, demonstrated for the first time the power of computer graphics as a method for controlling and interacting with computers.Simple computer graphics had earlier been created during the fifties to generate simple output displays. However, it was not until Ivan Sutherland developed his original software, that people became aware of the skills and potential of computer graphics.


The potential of the computer to create graphically enhanced productions, was, at first slow to develop. During this era there were three main barriers which often stopped people fully utilizing the powerful development which computers had to offer.The first was the high cost of computing during this time. This appeared in a number of different formats. Firstly the computer graphics which were created, especially if they were interactive, would become large in memory. The cost of this was very high and was hard to catch on and the cost demands couldn’t be met.

The only occasions when these could be justified was when universities and large industrial research laboratories used the computer to aid them with research.The second was the lack of understanding for the intricate controls of generating graphics, due to the then complicated picture generating software, which would be needed for an effective computer graphics system.  

The complex beginning of both systems of software and application was much underestimated. Many of the early graphics achievements were in fact impressive in them selves but rather inadequate when in comparison to the demands of professionally economically sound interactive graphic design applications.Due to many technological innovations, time favoured CGI. Computer equipment continued to drop in price year after year.

Also, during this era, operating systems were improved, and people ability to cope with complex was appearing less and less as the software became more sophisticated. Progress was made in the development of algorithms.

“Algorithms are a definite list of well-defined instructions for completing a task; that given an initial state will proceed through a well-defined series of successive states, eventually terminating in an end-state.The concept of an algorithm originated as a means of recording procedures for solving mathematical problems such as finding the common divisor of two numbers or multiplying two numbers”http://en.wikipedia.org/wiki/Algorithm.

Algorithms were successful in generating pictures, especially those which represented the views of 3D objects.Computer graphics entails both hardware and software technology. As with conventional numerical computing, we may have both batch and interactive modes.

In the early days of computer graphics, the main attention of the artists was given to the hardware side of CGI. Due to high performance hardware of the new age of computers, the attention to the hardware is a lot less and has shifted to the software side being a lot more appealing.
