The presentation focus on the giving the general concepts on how graphic can be produced by computer programs. The are several terminologies which was used in the presentation. Raster Image is the two dimensional image, Vector Image is an image which is created by mathematical algorithms as three dimensional images, Modeling is process of creating images similar to actual things, Texture is the process of building the surface, Animation is the rapid display of image in sequence, Rendering is the final process of creating an actual 2D image or animation from the prepared scene.
The history of computer graphic goes as early as ages of the 1960s the time when computer technology was rapidly gaining power to stand onto its feet like sketchpad program spacewar game and other animated graphics. In 1990s many films were created by graphical animation e.g. terminator 2, Toy story, beauty and beast. Many scenes contained 3D animated objects which were flat shaded with bright colors so as to blend with characters.
Computer graphics refers to any picture or series of pictures that is generated with the aid of computer. By discussion computer graphics refers to 3D graphics and not images created using 2D images or painting programs such as Photoshop, Gimp or Painter. The difference between 2D and 3D is that, most of 2D software is bitmap (raster) based, all 3D are vector based. Real time Graphics refers to computer graphics that signifies reality.
The field is applicable in movie industries where computer graphics characters are designed and associated in the movies. In other cases the full computer graphics movies are produced e.g. The movie of Madagascar and Bee Movie, also some times Movies that involves both computer graphics characters an humans are produced. E.g. Lord of the Ring, Star wars. The field is also applicable in the car model for designing car engine and the whole model. Games are designed by creating actors by computer graphics which animate the models. Medical Imaging and scientific visualization are used to design the teaching tools and diagnosis.
The advantages of this field is –
>It minimizes the cost of actual production/ construction in the field of Engineering.
>It gives more flexibility and allows complex effects and movies to be produced in film production.
>In games it allows real objects to be designed and programmed so that gaming becomes more interesting
>In medicine computer graphics simulation of body organs helps the process of studying the body easier.
The disadvantages of the computer graphics are as follows-
>It takes too much time to design the models depending on the size of scene.
>The computer graphic applications have got complicated interfaces which is difficult to be adopted by novice people
>Requires fast machines for fast rendering
>It takes the part of human actors in some of the movies/films thus these people are fired from their jobs
The computer graphics is the very complicated field though it is important to many fields like medicine, engineering, film production and all other technologies
