What is Points3D-Points3D is a software tool to handle the registration/alignment of pointcloud scans generated by 3D LiDAR laserscanners.It is also a pointcloud modeling tool, meaning pointclouds will be segmented into surfaces and meshed (triangulated) with a fast triangulation technique. This modeling allows to filter the pointclouds for relevant key surfaces and discard non interesting data. Triangulation may reduce data tremdously with many benefits: easier 3D navigation, cutting cumbersome
