Membuat Human 3D dengan Java 3D

Wednesday, May 18, 2016
Halo guys, kali ini saya mau share project kuliah saya dulu waktu semester tiga. Saya kepikiran daripada dibekam terus dilaptop mending di share aja, siapa tau berguna hehe. Disini saya membuat bentuk/kerangka human 3 dimensi. Bentuknya masih kasar banget, belum ada modelling, texture dan lainnya. Cuma berbentuk polosan saja, yakni sejumlah objek – objek yang digabungkan sehingga menyerupai bentuk human tiga dimensi.

Oke langsung ke TKP gan.
