PCL filter order

I'm using two filters on my pointcloud: CropBox to restrict points to a region and VoxelGrid to downsample the point cloud. Is it faster to run these in some particular order?

In almost all cases, it will be faster to run CropBox first, because it is very fast and can potentially eliminate a lot of points. How large the advantage is depends on your data: If you have a huge point cloud and a small target volume, so that CropBox removes 90% of points, the advantage will be greater than if CropBox only removes 10% of points.

That being said, VoxelGrid is quite fast too, so I suspect in most cases it wouldn't hurt too much to run VoxelGrid first (but there should almost never be an advantage to this).
