Primitif Drawing Kereta Api 1 Dimensi

Grafika komputer adalah cara membuat gambar atau grafik dengan menggunakan komputer. Dalam grafika komputer seseorang dianjurkan mempunyai daya imajinasi yang cukup lumayan karena grafika komputer terdiri dari koordinat titik - titik yang nantinya akan dihubungkan satu sama lainnya.

Pada pembahasan kali ini kita akan membahas tentang pembuatan kereta api 1 dimensi menggunakan visual C++, berikut langkah - langkahnya beserta source code sederhana yang dapat dikembangkan lebih lanjut. Sebelum membuatnya kita harus menambahkan openGL dapat di download di sini.

buka program file -> microsoft visual studio -> VCC -> include -> masukkan glut.h
buka program file -> microsoft visual studio -> VCC -> Lib-> masukkan glut32.lib
C: windows -> system -> masukkan glut32.dll
C: windows -> system32 -> masukkan glut32.dll

ini adalah contoh source code kereta api 1 dimensi
