Projact OpenGL # Membuat Boneka Sawah 3D Codeblock OpenGL

Seperti yang kita ketahui openGl adalah pemrograman untuk membuat gambar verktor biasanya untuk membuat sebuah game, desain rumah bahkan yang lainnya. namun perbedaannya dalam openGL kita membuat sebuah animasi dari dalamnya alias dari benar-benar nol.
   sedangkan aplikasi yang sudah dibuat sedemikian mudah itu membuat tidak benar-benar dari nol karena semua titik sudah banyak diaplikasikan ke aplikasinya tinggal pakai saja. sedangkan openGl tidak dia membuat semuanya dari benar-benar dasar.

pada kesempatan ini saya akan belajar membuat sebuah boneka sawah dari benar-benar nol. adapun langkah-langkah yang harus digunakan adalah sebagai berikut:

1. pastikan Codeblock kalian sudah terseting OpenGL yah.. untuk caranya dapat di cek disini
2. buat projek baru di codeblock caranya ada disini
3. kemudian copykan sourcode dibawah ini.

setelah semua sudah dikuti maka jalankan programnya dengan menekan F9. dan inilah dia hasilnya.
sangat indah dan menawan kan... keren kan.... demikian tutorialnya semoga bermanfaat. jangan lupa komennya dibawah yah kalau sudah mencoba dan bila ada pertanyaan.

berikut ini adalah efek dari keyboardnya:

• gunakan key up 
• keydown 
• keyleft 
• keyright

setelah program ini dibuat silahkan kalian coba sendiri di komputer kalian. semoga bermanfaat bagi yang mengerjakan tugas maupun yang sedang dalam masa belajar.
