Detailed Description

Core particle set.

The particles have the same radius.

Constructor & Destructor Documentation

ParticleSet::ParticleSet ( const double & r )

explicit

Create an empty set of particles.

Parameters

Parameters

r	Radius.
p	First particle.

Member Function Documentation

Append()

void ParticleSet::Append

(

const Vector &

p

)

Add a new particle to the set.

Parameters

p

Point.

At()

Sphere ParticleSet::At

(

int

k

)

const

Get the k-th particle.

Parameters

k

Index.

GetBox()

Box ParticleSet::GetBox

GetCircle()

GetSphere()

Sphere ParticleSet::GetSphere

(

)

const

Computes the bounding circle of the centers of the particles.

The exact embedding circle can be computed as:

ParticleSet particles;
Circle2 c=particles.GetCircle().Extended(particles.Radius());

Intersect() [1/2]

bool ParticleSet::Intersect

(

const Box &

box

)

const

Check the intersection between the cluster and a box.

Parameters

box

The box.

Intersect() [2/2]

bool ParticleSet::Intersect

(

const Sphere &

sphere

)

const

Check the intersection between the cluster and a circle.

Parameters

sphere

The sphere.
