[ros-users] Rotation Method to follow

[Tully Foote]

Prasad,
In general we have made the choice to use full 3D representations of points
and poses even when using 2d algorithms.  This allows 2d and 3d algorithms
to be able to interact without a translation layer.  If you're refering to
the position of an object in the world the standard representation is to use
a geometry_msgs/PoseStamped   To be able to manipulate these in Eigen or kdl
see the tf_conversions package. bullet support is built into the tf package
leveraging the bullet package.
