CONCLUSION
 INTRODUCTION

The representation manipulation of pictorial data by a computer.

The various technologies used to create and manipulate such
pictorial data.

The sub-field of Computer Science which studies methods for
digitally synthesizing and manipulating visual content.
 DESCRIPTION

Dynamic sorting provides the ability to change the sorting
direction in the report.

This sorting works on randomize the circles according to their
radius.

Circles that needs to be sorted in ascending order.
 ABSTRACT

The term computer graphics includes almost everything on
computers that is not text or sound. Today nearly all computers
use some graphics and users expects to control their computer
through icons and pictures rather than just by typing. Computer
graphics is the field of visual computing, where one utilizes
computers both to generate visual images synthetically and to
visual and special information sampled from the real world.
 HEADERFILES


“stdio.h”: This is the header file that includes the functions like
printf(), scanf() for read and write operations. It also includes the
file handling like open(), close(), etc.
“stdlib.h”: This is used to get some standard libraries.

“GL/glut.h”: This is to include the graphics built in OpenGL
function and utilities to build and implement our customized
graphics packages.

“string.h”: This is the header file that include the strings like
bitmap charcter() to read strings.

“math.h” : The math.h header defines various mathematical
functions and one macro. All the functions available in this
library take double as an argument and return double as the result.
 IMPLEMENTATION

void initialise(void)

In this function the swapping flag along with global variables that
holds the values of X coordinates during swapping are initialised
to zero. It also initializes the array of circles that is obtained from
the randomly generated sequence and place them at equal
intervals.

void bitmap_output(int x, int y, char *string, void *font)

This function is used to print the text on the visualizer window.

void int_str(int rad, char r[]);

This function does the conversion of integer value to string value,
so that it can be passed as parameter to the bitmap output
function.

void circle_draw(circle c);

This function draws the circle as per the passed circle structure
variable, which consist of the circle centre coordinates along with
the radius.

void swap_circles(circle *cc1,circle *cc2)

This function basically swaps the two key circles

void sort()

This function basically does the sorting process.

void display_text(void)

This function is going to display the text on the visualizer
window based on the sorting flag.

void display(void):-This function basically draws the circle.

void main_menu(int value):-This function basically calls the
display function based on the value passed as argument and also
based on sorting circle.

void reshape(int w , int h):-This function is used to reshape the
window with the new width and height which is passes as
parameter. This function is triggered whenever the current
window is reshaped.

void init(void)

This function uses three gl functions to initialize the current
window (i,e) glClearColor(),glMatrixMode(),gluOrtho2D() to set
the window background color and to define the 2D orthographic
projection matrix.

void main(int argc,char**agrv)

This is the function from where the execution of the program
begins. In this function we have certain “gl” functions used to
initialize the basic glut window with desired properties
 SNAPSHOTS
 NEEDSANDADVANTAGES

Arrange Data in a Systematic Representation.

Better Visualization and Understanding of Data.

Advantages of Analyzing Big Data by Sorting in Excel.

Reduce Huge Time Consumption in Research Surveys.

Advantages of No Requirement for Additional Storage by Sorting
Data in Excel.
 CONCLUSION

The development of mini project has given us a good exposure to
openGL by which we have learnt some of the techniques which
helps in the development of animation and gaming. Hence it is
helpful for us to even take this field as our career too and develop
some other features in openGL and provide as token of
contribution to the graphics world.

Understanding, analysis and design of sorting algorithms.
