ada banyak rasa saat coding. ada keringat dan air mata dalam mencoding. keringat saat kau berusaha menyelami makna dalam setiap ilmu coding. dan air mata disaat tiada orang yang dapat membantumu, ketika program dalam keaadaan bugging. apapun rasa dalam mencoding. cobalah untuk mengerjakan sendiri. sampai kau bisa. dan benar-benar bisa.

Make a Simple 2D Robot in OpenGL

Halo, sobat coding :)

Mengenai mata kuliah Grafika Komputer, kita akan belajar bagaimana cara membuat gambar pada komputer. Berikut ini adalah sebuah contoh 2D sederhana yaitu membentuk robot. Dalam membuat sebuah gambar kita membutuhkan library OpenGL

Untuk materi pengenalan Grafika Komputer dan dasar-dasar OpenGL, dapat Anda unduh di Pengenalan sistem grafika dan dasar-dasar penggunaan OpenGL pada dasar - dasar OpenGL
