  • adds non-stamped Eigen to Transform function
  • converts Eigen Matrix Vectors to and from geometry_msgs::Twist
  • adds to/from message for geometry_msgs::Pose and KDL::Frame

This PR is not ready for merge, but I figured I'd open it to get the discussion started. MoveIt! utilizes many different data type conversions in the old tf stack from eigen_conversions, kdl_conversions, and tf_conversions, and I'm attempting to convert everything to tf2.

Not all of the conversions from tf were present in geometry2, so I added those that I needed during the MoveIt migration. Caveats: I understand that the Twist type has representation issues, and that conversions are meant to be to/from Stamped types, but it seemed these conversions could still be useful.

That said, I am open to feedback on how to work with geometry2, so please let me know if I am off base in these additions.

Update comment to read Twist message, and Eigen Affine3d should read Eigen 6x1 Matrix

@tfoote Can you please take a look at this since it is necessary for the migration of MoveIt to tf2. Thanks.

The changes look good. The PR failure looks unrelated. I'll try retriggering it.

tf2 migration, resolves issue moveit#745
f4ebdc6 
- All type conversions now depend on geometry2 ROS packages, rather
  than geometry (see ros/geometry2#292 and
  ros/geometry2#294 for details of the new
  conversions)
- Removes all boost::shared_ptr<tf::TransformListener> from the API,
  and replaced them with std::shared_ptr<tf2_ros::Buffer>'s
- Piped tf2_ros::Buffer's everywhere where tf::TransformListeners were
  used
- Utilizes the new tf2 API in the tf::Transformer library to access
  the internal tf2::Buffer object used by RViz
  (see ros/geometry#163 for details of the
  new API)
- Removes the prepending of forward slashes ('/') for Transforms frames
  as this is deprecated in tf2

@tfoote @dirk-thomas Can you please consider these changes for cherry-picking to Kinetic?
MoveIt requires these changes for its melodic branch. However, we decided that this branch should also compile on Kinetic.

As I mentioned in moveit/moveit#902 (comment), the MoveIt maintainers need to discuss the decision to compile on both Melodic & Kinetic. There are several Melodic API changes that the MoveIt tf2 migration depends on:

geometry2: #292 & #294
ros/geometry#163
ros-visualization/rviz#1236

While I don't have a preference on what is backported (or not), I want to make sure we are all on the same page before making a decision.

I think all these changes target enabling of tf2. I think this is a valid goal not only for Melodic but also for Kinetic. Thus I ask you to consider backporting all of them. Instead of deprecating old functionality, it would suffice to add new functionality. I'm looking forward to your decision.

Since this is just additions or modifications to inline functions we can plan to backport this to kinetic.
