SYNOPSIS
Computer Graphics is one of the major facets in the computer industry. With the help of graphics package many applications like gaming, paint brush, entertainment, movies and other innovative applications can be run. The designed HAWK-EYE is to show how the LBW(leg before the wicket)can be simulated using the Computer graphics. The HAWK-EYE is interfaced with the MOUSE. We are using the different BUTTONS for working of the HAWK-EYE. The HAWKEYE can JUDGE the ball pitched inside the yellow zone or not. This HAWK-EYE is a simple and very basic demonstration of the application of computer graphics. Therefore, Therefore, as a whole, this is a simple s imple and useful demonstration for developing the interest in the graphics field of computers.

INTRODUCTION 1.1 OVERVIEW The Computer Graphics is one of the most effective and commonly used methods to communicate the processed information to the user. It displays the information in the form of graphics objects such as pictures, charts, graphs a nd diagram instead of simple text. In computer graphics, pictures or graphics objects are presented as a collection of discrete picture elements called pixels . The pixel is the smallest addressable screen element Comput Computer er graphi graphics cs today today is largel largely y intera interacti ctive: ve: The user user control controlss the content contentss structure, and appearance of objects and their displayed images by using input devices, such as a keyboard, mouse, or touch-sensitive panel on the screen Computer graphics concerns with the pictorial synthesis of real or imaginary objects from their computer based models, where as the the related field of image processing treats the converse process ,the analysis of scenes ,or the reconstruction of models of 2D or 3D objects from their pictures. The image processing can be classified as •
Image enhancement.
•
Pattern detection and recognition
•
Scene analysis and computer vision. The The imag imagee enhan enhance ceme ment nt deal dealss with with the the impr improve oveme ment nt in the the imag imagee quali quality ty by
eliminating noise or by increasing image contrast. Pattern detection and recognition deals with the detection and clarification of standard patterns and findin finding g deviati deviations ons from from these these patter patterns ns .The .The optica opticall charac character ter recogn recogniti ition on (OCR) (OCR) technology is an practical example for pattern detection & recognition. Scene analysis deals with the recognition and reconstruction of 3D 3 D model of scene from several 2D images.

1.2 ADVANTAGES OF INTERACTIVE GRAPHICS
It provide a tool for producing pictures not only of concrete, ”real-world” objects but also of abstract ,synthesis of objects. •
It as an ability to show moving pictures, and thus it is possible to produce animations.
•
With the use of interactive graphics we can control the movement of an object. The interactive graphics provides tool called motion dynamics. With this tool user can move and tumble objects with respect to stationary observer, or he can make object stationary and the viewer moving around them.
•
Interactive graphics provides facility called update dynamics.
•
With the recent development of digital signal processing (DSP) and audio synthesis chip chip the intera interacti ctive ve graphics graphics can now
provid providee audio audio feed back along along with the
graphical feed backs to make the simulated environment even more realistic
1.3 AREAS OF APPLICATION OF COMPUTER GRAPHICS
•
User interfaces
•
Plotting of graphs and charts
•
Office automation and Desktop publishing
•
Computer aided Drafting and designs
•
Process control
•
Cartography
OPENGL PROGRAMMING LANGUAGE : As a software interface for graphics hardware, OpenGL's main purpose is to render two- and three-dimensional objects into a frame buffer. These objects are described as sequences of vertices (which define geometric geo metric objects) or pixels (which define images). OpenGL performs several processing steps on this data to convert it to pixels to form the final desired image in the frame buffer.

2D TRANSFORMATIONS [Translation] Step 1: Initialize and draw the input object. Step 2: Accept the necessary input data (such as distance distance parameter, rotation angle, point of reference, shear parameters, scaling parameter) required for step 3 Step 3: To perform Translation:
x’ = x + dx
&
y’ = y + dy

USER DEFINED FUNCTIONS : This project is completed by using some of the Primary functions,first we finished with the ground dimensions using glBegin(GL_LINES)of width 5.0units ,next we did the patches on ground usin glColor[34]{f}(); then we drew pitch of dimensions 150units width,350units long.Which is done with the help of GL_POLYGON.. The screase on pitch is drawn using GL_LINES on appropriate length of the pitch and using same functions we did with STUMPS but of different width line. As we finished with stumps,next bails on the stumps is drawn by using glLineWidth() function,using same function screase on the pitch is drawn. Next we used Stroke manner of displaying STRINGS using set of polygons. Then we constructed fences using solid parellelogram,using GL_POLYGON and they are filled with blue and yellow color alternative

fashion. Then by using primitive function glutSolidSphere(GLdouble radius,GLint slices,GLint stacks);we finished with the ball. Next we placed the ball(i.e solid spehre) in appropriate position on the pitch,then we used translate() function and swapbuffers(); function in order to get movement of ball,this is achieved in project by LEFTCLICK of MOUSE button,the interaction is achieved by glutMouseFunc(mouse); in our project.as we press the MIDDLE_BUTTON we can observe the hault of the ball and again pressing the RIGHT_BUTTON we can easily judge the whether batsman is OUT or NOT!! We have used the function Sprint() to print the message the display using bitmap characters. Spindisplay() function is used move the ball before it pitches. Spindisplayy() function is used move the th e ball after it pitches.

4.CONCLUSION This This proj projec ectt was was impl impleme ement nted ed usin using g Open OpenGL GL.. This This proj projec ectt provi provide dess us the the information about various features of a hawk eye. This project also helps us to analyze how we can use the different standard functions for creating the animated objects and can be used for making a gaming package. This package is very useful for the users since it provides the basic information about various OpenGL functions used for hawk eye. This product has been demonstrated to fulfill the requirements. requirements. The functionality of all the modules and the module level integration is found to be satisfactory.
