C++ API

tf2

tf2 is the second generation of the tf library.

This library implements the interface defined by tf2::BufferCore.

There is also a Python wrapper with the same API that class this library using CPython bindings.

Code API

The main interface is through the tf2::BufferCore interface.

It uses the exceptions in exceptions.h and the Stamped datatype in transform_datatypes.h.

Conversion Interface

tf2 offers a templated conversion interface for external libraries to specify conversions between tf2-specific data types and user-defined data types. Various templated functions in tf2_ros use the conversion interface to apply transformations from the tf server to these custom datatypes.

The conversion interface is defined in tf2/convert.h.

Some packages that implement this interface:

• tf2_bullet

• tf2_eigen

• tf2_geometry_msgs

• tf2_kdl

• tf2_sensor_msgs

Some tutorials are available at https://docs.ros.org/.
