3D TRANSLATION AND SCALING

 

3D TRANSLATION AND SCALING

          AIM:

                        To write a program implementing  3D transformation as Translation and Scaling.

         ALGORITHM:

·         Start a program

·         Declare the variables and use graphics functions

·         Create the image to implements a 3D transformation

·         First image to translation P=T.P and change a image 3D scaling P=S.P

·         Print the output of 3D image translation and scaling

·         Stop the program

CODINGS:

#include<stdio.h>

#include<conio.h>     

#include<stdlib.h>

#include<graphics.h>

void main()

{

int x,y,z;

int x1=100,y1=150,x2=200,y2=250;

int a1=10,b1=20,a2=30,b2=40;

int gdriver=DETECT,gmode,errorcode;

initgraph(&gdriver,&gmode,"");

bar3d(x1,y1,x2,y2,(x2-x1)/4,1);

printf("Enter the translation value x&y:");

scanf("%d%d",&x,&y);

x1=x1+x;

x2=x2+x;

y1=y1+y;

y2=y2+y;

bar3d(x1,y1,x2,y2,(x2-x1)/4,1);

getch();

cleardevice();

bar3d(a1,b1,a2,b2,(a2-a1)/4,1);

printf("\nEnter the scaling factor a:");

scanf("%d",&z);

a1=a1*z;

a2=a2*z;

b1=b1*z;

b2=b2*z;

bar3d(a1,b1,a2,b2,(a2-a1)/4,1);

getch();

}

OUTPUT:

Enter the translation values x & y:

100

            200

Enter the scaling factor a:5

RESULT:

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