RUMAH GUNA OPEN GL

Malam ni kepala penin2 x taw nak wat cam ne.. ni sume gara-gara rumah idaman kalbu aku x siap lagi.. adoi la.
Ape-ape pun aku stil gak nak sharing gal pasal umah ni.. ni coding nye.. guna Visual C++. Mak... tolong.. da fenin.. Open GL ni aku belajar mase kelas asas grafik.. besh gak..tapi penin lagi.. da nak abeh kelas baru la paham cikit.. 2 baru cikit je.. yang banyak x taw la cam ne final ni..
contoh aturcara nya:

// testing rumah izzuera
#include <GL/glut.h>
void rumah( void)
{
    //rumah saya

ni lak hasil nye..huhu.. cun x?? cam ni la..budak baru nelajar bab open GL..
