Cara membuat gambar Bintang Berwarna di Microsoft Visual C++

     Setelah sebelumnya saya memposting Sintak gambar TV di Microsoft Visual C++, kali ini saya akan memposting bagaimana Cara membuat gambar Bintang Berwarna di Microsoft Visual C++. Aplikasi yang saya gunakan adalah Microsoft Visual C++ 2010 Express tapi bisa juga digunakan untuk Microsoft Visual C++ 2008. Untuk melihat bagaimana screenshoot ataupun sintaksnya silahkan lihat dibawah ini:

#include <stdlib.h>

#include <stdio.h>

#include <GL/glut.h>

{

float x;

float y;

};

typedef struct color_t

float g;

float b;

};

{

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

}
