Constructor Detail

VectorSet

public VectorSet(int numVectors)

Instantiate an empty set with the specified initial capacity and default load factor.

Parameters:

numVectors - the initial capacity of the hash table (>0)

Method Detail

add

public void add(Vector3f vector)

Add the value of the specified Vector3f to this set.

Parameters:

vector - the value to add (not null, unaffected)

contains

public boolean contains(Vector3f vector)

Test whether this set contains the value of the specified Vector3f.

Parameters:

vector - the value to find (not null, unaffected)

Returns:

true if found, otherwise false

mean

public Vector3f mean(Vector3f storeResult)

Calculate the sample mean for each axis over the Vector3f values in this set.

Parameters:

storeResult - (modified if not null)

Returns:

the sample mean for each axis (either storeResult or a new Vector3f)

numVectors

public int numVectors()

Calculate the number of Vector3f values in this set.

Returns:

the count (≥0)

toBuffer

public java.nio.FloatBuffer toBuffer()

Access the buffer containing all the Vector3f values in this set. No further add() is allowed.

Returns:

a new buffer, flipped
