Membuat Monas menggunakan Opengl

Asslamualaikum para mahasiswa yang selalu dikejar deadline tugas. kali ini, riska mau berbagi sorce code membuat objek monumen nasional atau biasanya kita nyebutnya monas. Disini riska pake opengl dan ngejalaninnya di microsoft visual studio 2010,langsung aja di coba,semoga bermanfaat.
Ini contoh outputnya :

Source code

#include <GL/glut.h>

typedef struct

{

int x,y;

}point2D_t;

typedef struct

{

float r,g,b;

}color_t;

void setColor(color_t col)

{

glColor3f(col.r, col.g, col.b);

}

void drawPolygon(point2D_t pnt[],int n)

{

int i;

glBegin(GL_LINE_LOOP);

for (i=0; i<n; i++)

{

glVertex2i(pnt[i].x,pnt[i].y);

}

glEnd();

}

void fillpolygon(point2D_t pnt[],int n,color_t color)

{

int i;

setColor(color);
