Membuat Bangunan 3D dengan Java 3D

Halo guys, ini adalah project saya dulu waktu masih kuliah semester 4. Ceritanya dikasih tugas untuk membuat objek 3D menggunakan Java 3D. Ide langsung muncul dipikiran saya untuk membuat bangunan masjid berbentuk 3D. Sebenarnya sih tugasnya disuruh buat objek sederhana saja, tapi entah kenapa saya selalu ingin membuatnya lebih sulit dan berbeda dari yang lainnya… :v. Alhamdulillah berkat kerja keras sehari semalam selesai nih tugas.

Tapi yang bikin repot itu adalah ketika tugasnya disuruh tulis tangan semua source codenya. Bayangkan aja apa gag pegel tangan ini menulis source code sekitar 600an baris … :’v *sory TS curhat

Oke langsung saja, berhubung saya mau sharing source codenya daripada dibekam terus di laptop. Silahkan bagi agan-agan boleh untuk memodifikasi/mengutak-atik source codenya.
