Cara Membuat objek Panah menggunakan Polygon di CodeBlocks

Tidak usah banyak basa basi gan, sedot aja langsung code di bawah ini hehehe

#include <windows.h>

#ifdef __APPLE__
#include <GLUT/glut.h>
#else
#include <GL/glut.h>
#endif

#include <stdlib.h>

void display()
{
glClear(GL_COLOR_BUFFER_BIT);
glPointSize(4);
glLineWidth(4);

glColor3f(1.0,0.0,0.0);

glBegin(GL_POLYGON);
glVertex2f(-1.8,0.7);
glVertex2f(0.0,0.7);
glVertex2f(0.7,0.7);
glVertex2f(0.7,-0.7);
glVertex2f(0.0,-0.7);
glVertex2f(-1.8,-0.7);
    glEnd();

glBegin(GL_POLYGON);
glVertex2f(0.7,1.2); //kiri
glVertex2f(1.9,0.0); //atas
glVertex2f(0.7,-1.2); //kanan atas

glEnd();

glFlush();
}

void myinit()
{
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluOrtho2D(-2.0,2.0,-2.0,2.0);
glMatrixMode(GL_MODELVIEW);
glClearColor(1.0,1.0,1.0,1.0);
glColor3f(0.0,0.0,1.0);
}

int main(int argc, char* argv[])
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(500,500);
//glutInitWindowPosition(100,100);
glutCreateWindow("Segitiga Warna");
glutDisplayFunc(display);
myinit();
glutMainLoop();

return 0;
}
