That's excellent news. I'll see if I can test our code with the new
release shortly. We've had performance issues in the past and had to
resort to offline map-building. It would be great if we could do that
online instead.

As you are probably aware of, we (Udo Frese's Realtime Vision Group here
in Bremen) use OctoMap to build a volumetric map in our visual SLAM
system developed as part of the SFB TR/8 A7 project. See [1] for a

Have you considered using Eigen2/3 for vector/matrix/quaternion math?
I would expect this to yield further performance improvements and it
would relieve you from maintaining your own matrix/quaternion library.
