CloudCompare, the open source 3D point cloud and mesh processing software, is used to perform analytics on the standardized sample. Statistical tools require points instead of a mesh; hence 1 million random, interpolated points are sampled from the mesh surface, yielding a point density of 100 points per mm2.

On the other hand, the management of the information processed is more convenient using specific and efficient software. Examples of programmes for data elaboration and management are PolyWorks® and Geomagic® — replacing Rapidform® XOS—, although MeshLab®(Cignoni et al. 2008) is also widely used as a free application with acceptable effectiveness. Among free software, CloudCompare® (Daniel Girardeau-Montaut n.d.) is complementary to the applications mentioned above as an analysis tool for point cloud data from TLS and photogrammetry; for instance, it allows for estimating the deviation between point-based and mesh-based objects. FugroViewer® (Fugro 2012) is another application to visualise point clouds and compare records (Liu et al. 2018), likewise it handles geospatial datasets. Hu and Yuan (Hu and Yuan 2016) used it to transform points into images.
