projek membuat pensil dengan openGL dalam bentuk 3D. full sourcode bisa langsung terapkan dan lihat hasilnya. dalam projek ini kita akan membuat pensil berwarna biru dengan layar berwarna hijau, adapun hasil dari sourcode ini adalah sebagai berikut :
langkah-langkagh untuk membuatnya adalah sebagai berikut.

semoga bermanfaat dan membantu teman-teman untuk menyelesaikan tugasnya.
langkah-langkagh untuk membuatnya adalah sebagai berikut.
- download terlebih dahulu openGL disini : View openGL
- setting codeblock dengan openGL caranya dapat dilihat disini: view
- buka codeblock dan buat projek baru caranya dapat dilihat disini : view
- copy semua sourcode yang tersedia di blog ini.
adapun sourcode yang tersedia adalah sebagai berikut ini :
