Projek Mini OpenGL( Lift-Over-Bridge) dengan pemrograman C++ dan CodeBlock


     Projek ini adalah sebuah projek mini animasi game dengan OpenGL C++ yaitu membuah sebuah projek yang diberi nama Lift-Over-Bridge. didaam projek ini akan ada animasi merubah warna perahu sebanyak 7 perubahan yaitu red, green, brown, cyan , magenta, white dan grey. animasi akan jalan otomatis dengan menggunakan event maouse clik. adapun hasil akhir dari projek ini adalah sebagai berikut :


Adapun untuk menjalankan projek ini anda harus memiliki semua software yang dibutuhkan diantaranya :
  1. Open GL download disini :  View openGL
  2. CodeBlock setting dengan openGL caranya lihat disini: view
  3. buka codeblock dan buat projek baru caranya dapat dilihat disini : view
  4. copy semua sourcode yang tersedia di blog ini.
sourcode yang dapat digunakan ada dibawah ini. silahkan copy projek dibawah ke projek yang dilakukan di langkah-langkah diatas.
