Translation Transformation

This Code Is One Of The Most Simplified Codes For Translation Transformation In C++

Functions Used:

1. getmaxx(); = is used for getting maximum value of the x co ordinate of the output screen.
2. getmaxy(); = is used for getting maximum value of the y co ordinate of the output screen.

Code:

#include<iostream.h>

#include<conio.h>

#include<graphics.h>

void main()

{

clrscr();

int gd=DETECT,gm,maxx,maxy,midx,midy,x1,y1,x,y,tx,ty;

initgraph(&gd,&gm,"C:\\Turboc3\\BGI");

maxx=getmaxx();

maxy=getmaxy();

midx=maxx/2;

midy=maxy/2;

setcolor(WHITE);

line(midx,0,midx,maxy);

line(0,midy,maxx,midy);

cout<<"enter x co-ordinates of the edges: ";

cin>>x1;

cout<<"enter y co-ordinates of the edges: ";

cin>>y1;

x=midx+x1;

y=midy-y1;

line(midx,midy,x,midy);

line(x,midy,x,y);

line(x,y,midx,y);

line(midx,y,midx,midy);

cout<<"Enter Translation factors:\ntx:";

cin>>tx;

cout<<"ty:";

cin>>ty;

setcolor(RED);

midx=midx+tx;

midy=midy-ty;

x=midx+x1;

y=midy-y1;

line(midx,midy,x,midy);

line(x,midy,x,y);

line(x,y,midx,y);

line(midx,y,midx,midy);

getch();

}

Output:
