Contoh Gambar Kreatif : Pemrograman Grafik "Televisi di Ruangan " Hasil Karya Siswa

Siswa memang dituntut untuk lebih kreatif mengasah segala kemampuannya. Salah satunya adalah kreatifitas siswa dalam membuat sebuah gambar dalam mata pelajaran Pemrograman Grafik.

Menggambar dalam pemrograman grafik tidak semudah kita menggambar di design grafik. Karena untuk menggambar di dalam pemrograman grafik, kita harus memahami konsep library dan penggunaanya. Objek yang kita buat bisa saja menggunakan library yang berbeda-beda. Tidak hanya itu, kita juga harus bisa menyesuaikan koordinat-koordinat x,y (untuk dua dimensi) atau x,y,z (untuk tiga dimensi).

Dalam penggambaran 2D (Dua Dimensi) ini siswa membuat  sebuah objek dimana televisi terletak di sebuah meja, di dalam ruangan. berikut screen shoot gambar hasil dari pemrograman menggunakan Visual Studio C++ 2008.
