6The <b>pcl_surface</b> library deals with reconstructing the original
7surfaces from 3D scans. Depending on the task at hand, this can be for
8example the hull, a mesh representation or a smoothed/resampled surface with
9normals.
10
11Smoothing and resampling can be important if the cloud is noisy, or if it is
12composed of multiple scans that are not aligned perfectly. The complexity
13of the surface estimation can be adjusted, and normals can be estimated in
14the same step if needed.

18Meshing is a general way to create a surface out of points, and currently
19there are two algorithms provided: a very fast triangulation of the original
20points, and a slower meshing that does smoothing and hole filling as well.

24Creating a convex or concave hull is useful for example when there is a need
25for a simplified surface representation or when boundaries need to be
26extracted.
