    • 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 Details

    • 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 FloatBuffer toBuffer()
      Access the buffer containing all the Vector3f values in this set. No further add() is allowed.
      Returns:
      a new buffer, flipped
