tf2::ATTRIBUTE_ALIGNED16 ( class )

The QuadWord class is base class for Vector3 and Quaternion. Some issues under PS3 Linux with IBM 2.1 SDK, gcc compiler prevent from using aligned quadword.

tf2::Vector3 can be used to represent 3D points and vectors. It has an un-used w component to suit 16-byte alignment when tf2::Vector3 is stored in containers. This extra component can be used by derived classes (Quaternion?) or by user Ideally, this class should be replaced by a platform optimized TF2SIMD version that keeps the data in registers

template<typename A , typename B >

B tf2::toMsg ( const A & a )

Function that converts from one type to a ROS message type. It has to be implemented by each data type in tf2_* (except ROS messages) as it is used in the "convert" function.

Parameters

a	an object of whatever type

Returns: the conversion as a ROS message

void tf2::transformMsgToTF2	(	const geometry_msgs::Transform &	msg,
		tf2::Transform &	tf2
	)

convert Transform msg to Transform
