Detailed Description

Off-lattice Eden growth.

Constructor & Destructor Documentation

EdenGrowth() [1/4]

EdenGrowth::EdenGrowth ( const double & r = 1.0 )

explicit

Create an Eden growth structure.

Set initial circle as empty, and list of particles as empty.

Parameters

r	Radius of particles.

EdenGrowth() [2/4]

EdenGrowth::EdenGrowth ( const Vector & c, const double & r )

explicit

Create an Eden growth structure.

Parameters

c	Initial particle position.
r	Radius of particles.

EdenGrowth() [3/4]

EdenGrowth::EdenGrowth ( const QVector< Vector > & p, const double & r )

explicit

Create an Eden growth structure.

Parameters

p	Set of seed points.
r	Radius of particles.

EdenGrowth() [4/4]

EdenGrowth::EdenGrowth ( const ParticleSet & particles )

explicit

Create an Eden growth structure.

Parameters

particles

Set of particles.

Member Function Documentation

AddCell()

void EdenGrowth::AddCell

(

const Vector &

c

)

Add a new particle to the cluster.

If the particle intersects the cluster, it automatically dies and is not added to the cluster.

Otherwise, it is added as a living particle.

GrowthSites()

int EdenGrowth::GrowthSites ( const Vector & q, Vector * sites ) const

protectedvirtual

Find candidate growth directions from a particle.

This function has an O(n) complexity.

Parameters

q	Position of the candidate particle.
sites	Array of returned growth positions.

Returns

the number of candidate growth directions.

Step() [1/2]

void EdenGrowth::Step ( )

virtual

Add a new particle to the cluster.

Select a random particle in the existing cluster, and compute candidate growth directions. Repeat random selection until a valid particle is found. Then select a randomly generated growth direction and update the cluster.

This function has an O(n) complexity.

Step() [2/2]

void EdenGrowth::Step ( int n )

virtual

Perform several growth steps.

Parameters

n	Number of growth steps.
