Constructor Details

BrightestStarsSimple

public BrightestStarsSimple(int maxPart)

Constructor using fields

Parameters:

maxPart - Number of objects in the densest node of this level

Method Details

sample

public boolean sample(List<IParticleRecord> inputStars,
 OctreeNode octant,
 float percentage)

Description copied from interface: IAggregationAlgorithm

Creates the sub-sample from the given input stars. All these stars should be in the box defined by the center and the sizes.

Specified by:

sample in interface IAggregationAlgorithm

Parameters:

inputStars - The actual stars that are inside the octant.

octant - The octant that characterizes the box with its center, size and depth well set.

percentage - The percentage of objects to be included in the octant.

Returns:

True if we are in a leaf.

getMaxPart

public int getMaxPart()

Description copied from interface: IAggregationAlgorithm

Specified by:

getMaxPart in interface IAggregationAlgorithm

Returns:

maximum number of particles in a node

getDiscarded

public int getDiscarded()

Description copied from interface: IAggregationAlgorithm

Returns the number of discarded stars by this algorithm so far.

Specified by:

getDiscarded in interface IAggregationAlgorithm

Returns:

The number of stars discarded.

getMaxDepth

public int getMaxDepth()

Description copied from interface: IAggregationAlgorithm

Returns the max depth setting.

Specified by:

getMaxDepth in interface IAggregationAlgorithm

Returns:

The max depth
