TUGAS GRAFKOM Q 2

Friday 7 December 2012

membuat LAMPU HIDUP MATI, di tengah ruangan .
keterangan : 
pakek openGL microsoft visual c++ 2010 express.
lampu hidup mati bisa di control dengan meng klik tombol di keyboard

  • tombol R : nyala warna putih.
  • tombol G : nyala warna hijau.
  • tombol B : nyala warna  kuning.
  • tombol 0 : mati .
  • trus klo dilik kanan mouse. ruangan akan berputar ke kanan.
  • kalo di klik kiri . ruangan akan berputar ke atas.
