gan kalo code geometry yang gerak ada ga gan?
ane mnt donk source code+ langkah - langkahnya donk

gan ane juga minta code stimulasi leading ama take off pesawat terbang ada ga gan??
ane bagi donk ...

1 lagy gan ini w ada tugas grafkom lep
ane ambil judul Animasi Pengenalan Bangun Ruang
ada source code ma langkah - langkahnya ga?
thanks
