In this article, we’ll be implementing a program to demonstrate 2D scaling of a triangle in computer graphics using C.
Scaling can be defined as a process of changing or altering the size of an object. It can be used to increase or decrease the size of the respective object. Below is the program:
program:
#include<stdio.h> #include<conio.h> #include<graphics.h> void main(){ int x,y,x1,y1,x2,y2; int scl_fctr_x,scl_fctr_y; int gd=DETECT,gm; initgraph(&gd,&gm,"C:\\TURBOC3\\BGI"); printf("\t\t\t********** Scaling ***********\n"); printf("\n\t\t\t Please enter first coordinate of Triangle = "); scanf("%d %d",&x,&y); printf("\n\t\t\t Please enter second coordinate of Triangle = "); scanf("%d %d",&x1,&y1); printf("\n\t\t\t Please enter third coordinate of Triangle = "); scanf("%d %d",&x2,&y2); line(x,y,x1,y1); line(x1,y1,x2,y2); line(x2,y2,x,y); printf("\n\t\t\t Now Enter Scaling factor x and y = "); scanf("%d %d",&scl_fctr_x,&scl_fctr_y); x = x* scl_fctr_x; x1 = x1* scl_fctr_x; x2 = x2* scl_fctr_x; y = y* scl_fctr_y; y1 = y1* scl_fctr_y; y2= y2 * scl_fctr_y ; line(x,y,x1,y1); line(x1,y1,x2,y2); line(x2,y2,x,y); getch(); closegraph(); }
Output:
