@huanglilong I am not sure what you are asking me to do? Seems to me like it is the VTK maintainer's turn to investigate the problem, since it is likely...

@themightyoarfish I would want to avoid depending on a logging library if possible. Adding new dependencies is always a big pain (need to check the license, need to make sure...

> the use of EIGEN_ALIGN16 seems to be a very bad idea. In particular for cache efficiency and multithreading. How so? Because it may "waste" memory? Correct me if I...

`EIGEN_ALIGN16` was never meant to create a memory layout beneficial for multi-threading. Can you describe more, what you are working on? You use multi-threading to compute something, and store the...

My assessment of the situation: If we wanted to support external/system metslib, we would still have to keep the metslib shipped with PCL, because not many package managers offer it:...

It could make sense to use `pcl::search::Search` instead of `pcl::search::KdTree`, then other search methods such as organized search and octree would be possible. But I am not sure what to...

> I am a bit confused anyway why the `Registration` class has methods to set the search method, while that should be the `CorrespondenceEstimation`s job, shouldn't it? This might be...

@adconk You could try to create a custom build of PCL while removing boost-filesystem as a dependency. boost-filesystem is mainly used in the modules apps, io, outofcore, tools, and visualization....

Hi, I understand your point. The problem that PCL's io module depends on VTK (and thus entails a lot of dependencies on Debian/Ubuntu) also came up in perception_pcl (the ROS-PCL...

@jackjansen Sorry for the misunderstanding: PCL does have functions to load and save ply and obj files, which do not depend on VTK: `loadPolygonFilePLY`, `loadPolygonFileOBJ`, and `savePolygonFilePLY` for example depend...
