OPENGL HELLO WORLD !
- Halo man teman, dipostingan ini saya akan membagikan sedikit pengetahuan tentang OpenGL. OpenGL adalah Spesifikasi standar yang mendefinisikan sebuah lintas bahasa dan platform API untuk mengembangkan aplikasi 2D maupun 3D. Kali ini saya akan membagikan syntax tulisan Hello World menggunakan OpenGL dan bahasa C++.
