2D REFLECTION

2D REFLECTION

AIM:

                      To write a program to implement 2D transformation as reflection

          ALGORITHM:

·         Declare the header file

·         Declare the variables and values

·         Using the graphics function create an image to implement the 2D reflection

·         Print the output of 2D image reflection

·         Stop the program

                       

CODINGS:

#include<stdio.h>

#include<conio.h>

#include<graphics.h>

void main()

{

int a,a1,b,b1,c,c1,xt,ch;

int gd=DETECT,gm;

initgraph(&gd,&gm,"");

a=getmaxx();

a1=getmaxy();

b=a/2;

b1=a1/2;

line(b,0,b,a1);

line(0,b1,a,b1);

line(400,200,600,200);

line(400,200,400,100);

line(400,100,600,200);

printf("1.origin\n");

printf("2.x-axis\n");

printf("3.y-axis\n");

printf("4.exit\n");

do

printf("Enter your choice\n");

scanf("%d",&ch);

switch(ch)

{

case 1:

      c=400-b;c1=200-b1;

      line(b-c,b1-c1,b-c-200,b1-c1);

      line(b-c,b1-c1,b-c,b1-c1+100);

      line(b-c,b1-c1+100,b-c-200,b1-c1);

      break;

case 2:

      c=400-b;c1=200-b1;

      line(b+c,b1-c1,b+c+200,b1-c1);

      line(b+c,b1-c1,b+c,b1-c1+100);

      line(b+c,b1-c1+100,b+c+200,b1-c1);

      break;

case 3:

      c=400-b;c1=200-b1;

      line(b-c,b1+c1,b-c-200,b1+c1);

      line(b-c,b1+c1,b-c,b1+c1-100);

      line(b-c,b1+c1-100,b-c-200,b1+c1);

      break;

}         

}while(ch<4);

getch();

closegraph();

}

OUTPUT:

1.      origin

2.      x-axis

3.      y-axis

   

      Enter your choice:1

      Enter your choice:2

      Enter your choice:3

                                                                                                                                              

RESULT:

           

            Thus, the program has been successfully executed & output is verified.
