Member Function Documentation

◆ computeMainAxis()

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

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

The principal component vectors are established internally.

◆ getCenterOfMass()

Vector3 ml::MainAxisPCA::getCenterOfMass ( ) const

Returns the center of mass of the object, which is the mean of all 3d points.

◆ getExtension()

void ml::MainAxisPCA::getExtension	(	float &	longestExtent,
		float &	midExtent,
		float &	shortestExtent
	)		const

Returns the three extents of the object aligned bounding box, largest first.

◆ getLargestExtension()

float ml::MainAxisPCA::getLargestExtension ( ) const

Returns the largest extend of the object aligned bounding box.

◆ getLargestMainAxis()

Vector3 ml::MainAxisPCA::getLargestMainAxis ( ) const

Returns a copy of the largest main axis.

◆ getMainAxis()

void ml::MainAxisPCA::getMainAxis	(	Vector3 &	longestAxis,
		Vector3 &	midAxis,
		Vector3 &	shortestAxis
	)		const

Returns the main axes (normalized). The axes are sorted by extent, largest first.

◆ getMidPoint()

Vector3 ml::MainAxisPCA::getMidPoint ( ) const

Returns the middle point of the object aligned bounding box.
