Why is computer graphics important?

The importance of computer graphics lies in its applications. In engineering applications (e.g. automotive and aeorspace), the ability to quickly visualize newly designed shapes is indispensible. Before the advent of computer graphics, designers built expensive prototypes and time-consuming clay models. Now, designers can interactively view and modify models of their shapes using a computer.

Medical imaging is another application where computer graphics has proven valuable. Recent advances in imaging technology such as computer tomography and magnetic resonance imaging allow physicians to take 3D Xrays of the human body. Interactive computer graphics allows the physician to interpret this large volume of data in new and useful ways.

Computer graphics has also expanded the boundaries of art and entertainment. Movies such as Jurassiac Park make extensive use of computer graphics to create images that test the bounds of imagination. The development of computer graphics has made possible virtual reality, a synthetic reality that exists only inside a computer. Virtual reality is fast becoming an indispensable tool in education. Flight simulators are used to train pilot for extreme conditions. Surgical simulators are used to train novice surgeons without endangering patients.

There are a lot of importance in our daily life. Here I mention some uses computer graphics. The techniques that have been used in this example are modelling shapes, layout and animation, and rendering. The modelling process can be through polygonal modelling in which dots are connected and the faces of the polygons that result create the image of the objects. A layout and animation technique involves placing the object within the scene. Commonly, some of methods that used in this technique are motion capture of movements, determining the proper angular positions of the elements of the jointed object, and key framing, which is defined the start and end points of a smooth transition through frames. Movement is created by displaying a series of images that are similar to one another on the screen to create the illusion of movement. The frames then can be replaced by a virtual skeleton and the computer automatically calculates the differences in the appearance among succeeding frames. The rendering is the technique where the model is translated into an image by integrating lighting effects such as shadows and scatting of light. In this technique it determines how the light is reflected or refracted from a surface at any point in the object and how the properties of the object materials vary on the surface.
