membuat animasi mobil 3D dengan OpenGL codeBlock C++
projek openGl banyak di blog tapi kebanyakan sulit dicoba sendiri. berikut ini saya beri satu full sourcode membuat animasi dengan openGL terutama untuk membuat game sederhana beserta tutorial cara penggunakan codeblock sampai bisa menggunakan openGL.
adapun hasil akhir dari projek kali ini adalah sebagai berikut

hasil akhir ketika dicompile dan di jalankan maka akan menghasilkan tampilan seperti dibawah ini.
semua instruksinya sudah tedapat di layar kalian masing-masing:
adapun hasil akhir dari projek kali ini adalah sebagai berikut
projek ini membuat mobil dengan beberapa fitur dalam animasinya seperti :
- putar arah y
- putar arah x
- putar arah z
- tingkatkan ukuran mobil dalam arah x
- tingkatkan ukuran mobil dalam arah y
- tingkatkan ukuran mobil dalam arah z
- tampilan atas kamera
- tampilan samping kamera
- gerakan mobil kearah depan
- gerakan mobil kearah belakang
- tombol keluar dari animasi
Adapun langkah -langkah dalam membuatnya adalah sebagai berikut :
- Download OpenGL terlebih dahulu disini : download
- Setting codeblock dengan opengl. kalau belum tau caranya dapat dilihat disini "cara setting OpenGl ke codeblock"
- Buka editor codeblock cara memulai projeknya dapat dilihat disini : view
- Copy kode dibawah ini kemudian jalankan.

hasil akhir ketika dicompile dan di jalankan maka akan menghasilkan tampilan seperti dibawah ini.
semua instruksinya sudah tedapat di layar kalian masing-masing:
- Y = putar arah y
- X = putar arah x
- Z = putar arah z
- A = tingkatkan ukuran mobil dalam arah x
- S = tingkatkan ukuran mobil dalam arah y
- tingkatkan ukuran mobil dalam arah z
- U = tampilan atas kamera
- F = tampilan samping kamera
- tombol arah kiri = gerakan mobil kearah depan
- tombol arah kanan = gerakan mobil kearah belakang
- Esc = tombol keluar dari animasi
- spasi = masukan layar utama dari layar awal
