Constructor & Destructor Documentation

ml::MainAxisPCA::MainAxisPCA ( )

Constructor.

virtual ml::MainAxisPCA::~MainAxisPCA ( ) [virtual]

Destructor.

void ml::MainAxisPCA::computeMainAxis ( const std::vector< ml::Vector3 > & points )

Computes the main axes on behalf of the given point cloud.

The principal component vectors are established internally.

ml::Vector3 ml::MainAxisPCA::getBaryCenter ( )

Returns the barycenter (center of mass) of the object.

void ml::MainAxisPCA::getExtension	(	float &	xExt,
		float &	yExt,
		float &	zExt
	)

Returns the three extends of the object aligned bounding box.

float ml::MainAxisPCA::getLargestExtension ( )

Returns the largest extend of the object aligned bounding box.

float* ml::MainAxisPCA::getLargestMainAxis ( )

Returns a copy of the largest main axis.

void ml::MainAxisPCA::getMainAxis	(	ml::Vector3 &	xAxis,
		ml::Vector3 &	yAxis,
		ml::Vector3 &	zAxis
	)

Returns the main axes.

ml::Vector3 ml::MainAxisPCA::getMidPoint ( )

Returns the middle point of the object aligned bounding box.
