Membuat Animasi Kendaraan Beroda Empat 3D Dengan Java 3D
Halo guys, kali ini aku mau share project kuliah aku dulu. Masih di grafika komputer, aku menciptakan kerangka kendaraan beroda empat 3D dengan Java 3D dan ini tidak mengecewakan sulit. Sulitnya itu sebab kita harus menggambar manual mulai dari bentuk shape dan pola-polanya. Kalau di Java 3D kita dapat memakai Point3f. Dengan Point3f kita dapat menciptakan kerangka bentuk 3D dengan menyatukan titik-titik atau koordinat x, y, z, maka terbentuklah bidang geometrinya.
Kemudian untuk mengatur animasinya memakai kelas Alpha dan PositionInterpolator.
Oke meluncur ke TKP gan.
Sekian dan biar bermanfaat
