Karena menggunakan software Pelles C, maka obyek yang dibuat murni dibuat dengan coding program. Semua pengaturan yang berhubungan dengan obyek baik itu warna, ukuran serta posisi obyek berikut pergerakkan obyek tersebut diatur didalam coding program. Untuk memulai Pelles C (klik untuk yang mengunduh) langkahnya adalah sebagai berikut :
1. Klik start - All Programs - Pelles C for Windows - Pelles C IDE
2. Pilih File - New - Project
3. Pilih wizard yang sesuai - masukkan nama - OK
4. Kemudian next, lalu Finish
5. Double Click pada main.c
6. Maka akan muncul project area untuk menuliskan coding.
7. Coding dituliskan didalam komentar //lakukan penggambaran disini.
8. Jadi, kita mulai membuat coding di blok //lakukan penggambaran disini.
9. Selebihnya merupakan struktur yang sudah tersedia dan tidak perlu diubah - ubah.
berikut codingnya.

glMatrixMode( GL_PROJECTION );
glLoadIdentity();
gluPerspective( 60.0f, 640.0f/480.0f, 0.1f, 1000.0f );
Dan pada saat program di execute maka menghasilkan output
semoga bermanfaat
