Implementation of Particle.cpp file : First, we have to include the appropriate files :

#include "Particle.h"


The constructor and copy constructor :

///Default constructeur of Particle
Particle::Particle(){
	initialisationParticle();
}

///Copy constructor of Particle
/**	@param other : class to copy
*/
Particle::Particle(const Particle & other){
	copyParticle(other);
}


The destructor :

///Destructeur of Particle
Particle::~Particle(){
	
}


The equal operator :

///Definition of equal operator of Particle
/**	@param other : class to copy
 * 	@return copied class
*/

	copyParticle(other);
	return *this;
}


Random initialisation :

///Initialise randomly the Particle

	float boxHalfSize(1.0f), velocity(0.005f);
	p_position.setComposante(randfloat(-boxHalfSize, boxHalfSize), randfloat(-boxHalfSize, boxHalfSize), randfloat(-boxHalfSize, boxHalfSize));
	p_velocity.setComposante(randfloat(-velocity, velocity), randfloat(-velocity, velocity), randfloat(-velocity, velocity));
	p_acceleration.setComposante(0.0f, 0.0f, -9.81f);
}


Moving the Particle :

	p_velocity += p_acceleration*dt;
