Posted in Computer on 03/01/2009 12:01 am by adminThe concept of computer graphics (CG) has helped to set high standards in gaming and entertainment field. Pixels are the basic components of a CG screen. Pixels have many properties such as color, display On/Off, brightness. Based on the values assigned to these properties the pixels are displayed. For instances if the display property is set off, the pixel will not be displayed.
A collection of pixels form a line. Bresenham’s line generation algorithm explains this functionality. A collection of lines which forms a closed side creates polygon. Based on this the images are drawn. In 2-D images scaling and rotations are used to move the images. The 3-D images are created using highly sophisticated tools.
