gtsam::OrientedPlane3 Class Reference

Represents an infinite plane in 3D, which is composed of a planar normal and its perpendicular distance to the origin. Currently it provides a transform of the plane, and a norm 1 differencing of two planes. Refer to Trevor12iros for more math details. More...

Vector3 gtsam::OrientedPlane3::errorVector	(	const OrientedPlane3 &	other,
		OptionalJacobian< 3, 3 >	H1 = boost::none,
		OptionalJacobian< 3, 3 >	H2 = boost::none
	)		const

Computes the error between the two planes, with derivatives. This uses Unit3::errorVector, as opposed to the other .error() in this class, which uses Unit3::localCoordinates. This one has correct derivatives. NOTE(hayk): The derivatives are zero when normals are exactly orthogonal.
