Membuat LineStrip

 

Syntax :

//header file

#include <stdlib.h>

#include <gl/glut.h>

//fungsi untuk menggambar garis

void drawPoliline(){

     glClear(GL_COLOR_BUFFER_BIT);

     glLineWidth(10);

     glBegin(GL_LINE_STRIP); //menggambar sekelompok vertex yang saling terhubung

           glColor3f(1,0,0);

           glVertex2d(-120, -80);

           glColor3f(0,1,0);

           glVertex2d(120, 80);

           glColor3f(0,0,1);

           glVertex2d(120, -80);

           glColor3f(0, 1, 1);

           glVertex2d(-120, 80);

     glEnd();

     glFlush();

}

//fungsi callback

void renderScene(void){

           drawPoliline();

}

//fungsi main

void main(int argc, char **argv){

     glutInit(&argc, argv);

     glutInitDisplayMode(GLUT_DEPTH | GLUT_SINGLE | GLUT_RGBA );

     glutInitWindowPosition(100,100); //posisi window

     glutInitWindowSize(320, 240);  //ukuran window

     glutCreateWindow("POINTS : RACHMAT SANTOSO && INDRA MAULANA");

           gluOrtho2D( -320.0, 320.0, -240.0, 240.0);

     glutDisplayFunc(renderScene); //callback function

     glutMainLoop(); //looping fungsi main
