LCD slowly transit between states. In scanned displays, with a large number of pixels, the percentage of the time that LCDs are excited is very small.

Crystals spend most of their time in intermediate states, being neither "On" or "Off". These displays are not very sharp and are prone to ghosting.

Plasma display: Figure1. In a raster scan system, the electron beam is swept across the screen, one row at a time from top to bottom. As the electron beam moves across each row, the beam intensity is turned on and off to create a pattern of illuminated spots.

In a random scan display, a CRT has the electron beam directed only to the parts of the screen where a picture is to be drawn. Random scan monitors draw a picture one line at a time.

There are some parameters or properties related to graphic displays like CRT: Persistence: In case of CRT, persistence refers to the property of a phosphor defining its life time, i. Resolution: The maximum number of points that can be displayed without overlap on a CRT is referred to as the resolution. In other words, it is the number of points per unit length that can be plotted horizontally and vertically.

Frame buffer: Frame buffer also known as refresh buffer is the memory area that holds the set of intensity values for all the screen points. Pixel: It refers a point on the screen. It is also known as pel and is shortened form of picture element.

Bitmap or pixmap: A frame buffer is said to be bitmap on a black and white system with one bit per pixel. For systems with multiple bits per pixel, the frame buffer is referred to as pixmap.

Graphical images - used to add emphasis, direct attention, illustrate concepts, and provide background content. Two types of graphics: o Draw-type graphics or vector graphics represent an image as a geometric shape o Bitmap graphics represents the image as an array of dots, called pixels Three basic elements for drawing in graphics are: o Point: A point marks a position in space.

In pure geometric terms, a point is a pair of x, y coordinates. It has no mass at all. Graphically, however, a point takes form as a dot, a visible mark. A point can be an insignificant fleck of matter or a concentrated locus of power. It can penetrate like a bullet, pierce like a nail, or pucker like a kiss. A mass of points becomes texture, shape, or plane.

Tiny points of varying size create shades of gray. Understood geometrically, a line has length, but no breadth.

A line is the connection between two points, or it is the path of a moving point. A line can be a positive mark or a negative gap. Lines appear at the edges of objects and where two planes meet. Graphically, lines exist in many weights; the thickness and texture as well as the path of the mark determine its visual presence.

Lines are drawn with a pen, pencil, brush, mouse, or digital code.

Part of the Communications in Computer and Information Science book series CCIS, volume Abstract In the line clipping procedures if the line is not completely inside the clipping window then we have no option but to divide the line into segments at the intersections of the line and clipping window edges and then identify which segment is inside and which segment is outside the clipping window.

This paper presents the mechanism by which the remaining 14 cases can be solved without dividing the line into segments. Dimensional computer-synthesized imagery, redefining the original. This book introduces students to the core concepts of computer graphics with full integration of OpenGL and an emphasis on application-based programming.
