Abstract

Penempatan posisi kamera secara manual membutuhkan proses dan perhitungan yang berulang-ulang untuk sebuah adegan, tentu saja hal ini akan membutuhkan banyak waktu dan biaya. Oleh karena itu dibuat sebuah sistem penempatan posisi kamera secara otomatis dalam lingkungan virtual yang sesuai dengan kaidah sinematografi. Sistem akan menangani pengaturan kamera untuk mendapat sudut, jarak dan ketinggian  yang cocok untuk setiap adegan. Penelitian ini akan menggunakan simulasi permainan komputer dengan beberapa aksi dengan dua macam gaya penempatan posisi kamera yaitu kamera statis dan kamera dinamis. Metode yang digunakan adalah logika fuzzy dengan metode mamdani. Terdapat 3 tahapan yang dilakukan yaitu tahap masukan dari pengguna berupa kombinasi penekanan tombol untuk melakukan sebuah aksi. Tahap kedua adalah sistem inferensi fuzzy yang akan mengolah input menjadi output. Tahap terakhir adalah perekaman aksi berdasarkan posisi kamera yang telah ditentukan. Selain itu dalam simulasi permainan ini akan dipasang modul event selector  untuk validasi aksi dan modul state director untuk operator transisi kamera virtual. Uji coba dilakukan dengan cara merekam 7 macam aksi dan akan divalidasi berdasarkan profiling dan responden.  Dari uji coba didapatkan nilai 3.66 untuk kamera statis dan 4.08 untuk kamera dinamis. Hal ini menunjukkan bahwa sistem yang dibangun mampu melakukan penempatan posisi kamera sesuai kaidah sinematografi.
