copy

public BoundingBox copy(BoundingBox copy)

fromVertices

public BoundingBox fromVertices(Vertex[] vertices)

Calculates a BoundingBox from Vertex Array. Only takes positions into account. The outter most vertices will be directly on the edge of the bounding box.

Parameters:

vertices - Vertex Array. Positions are required only

Returns:

this

fromVertices

public BoundingBox fromVertices(Vertex[] vertices,
                       float padding)

Calculates a BoundingBox from Vertex Array. Only takes positions into account. The outter most vertices will be directly on the edge of the bounding box. After this the padding will get added to all sides.

Parameters:

vertices - Vertex Array. Positions are required only

padding - Will get added to all sides (extends, after the calculation) should be 0 in most cases

Returns:

this

fromPoints

public BoundingBox fromPoints(List<Vector3f> vectors)

Calculates a BoundingBox from list of points (Vector3f s). The outter most points will be directly on the edge of the bounding box.

Specified by:

fromPoints in class BoundingObject

Parameters:

vectors - List of vectors to be contained by this boundingbox

Returns:

this

fromPoints

public BoundingBox fromPoints(List<Vector3f> vectors,
                     float padding)

Calculates a BoundingBox from list of points (Vector3f s). The outter most points will be directly on the edge of the bounding box. (not if padding is added!)

Parameters:

vectors - List of vectors to be contained by this boundingbox

padding - Will get added to all sides (extends, after the calculation) should be 0 in most cases

Returns:

this
