TUGAS Grafika Komputer

Gambar apa sih diatas??

Kalau kaliann lihat hanya sekilas, kalian pastinya tidak mengerti..
Tetapi jika kalian lihat dengan seksama, itu merupakan gambar 3D yaitu " KUBUS BERGAMBAR "

Jikakalian tertarik dengan cara pembuatannya, berikut ini adalah kodingnya.. :D

IT'S CODING TIME !!! :D :D
