[ros-users] ANN, template, caching

[Radu Bogdan Rusu]

Dear Stephane,

There are no plans to change ANN. We might however move completely to FLANN. Note that PCL has interfaces to both.

That being said, Marius (Muja - the author of FLANN) and I -- at least -- would be happy to talk to you offline about 
the kind of changes you're interested in.

Cheers,
Radu.
