Firework

Installation

Pour ce projet, vous devez avoir sur votre machine :

• Une distribution d'OpenGL 4.5
• La bibliothèque glew
• La bibliothèque GLUT
• La bibliothèque glfw3
• Un compilateur C++

Lancement

./linux.sh
./firework

Introduction

Le projet Firework a pour but de modéliser en 3D un feu d'artifice ainsi que le canon par lequel ceux-ci sont lancé. Pour cela, nous utilisons l'API OpenGL.
