Point Cloud

A point cloud is a unorganised set of points, that usually represent the surface of an object.

Every point in a point cloud has a set of coordinates as well as possible other metadata like colour, normal vector, scan precision, and recording timestamp.

Uses

When laser scanning, point clouds are directly created by the scanner, whereas in photogrammetry the point cloud is a result of one of the computation steps.

Photogrammetry software, as well as other software can reconstruct a mesh from a point cloud.
