Point cloud
From Wikipedia, the free encyclopedia
In computer science, a point cloud is a set of three-dimensional points describing the outlines or surface features of an object, such as that produced by a 3D digitizer.
In manufacturing, a point cloud usually refers to set of densely sampled or high-definition dimensional measurements of a manufactured part's surface so as to enable comparison of the actual manufactured or fabricated part to a (usually faceted or vectorized) "computer-aided design" / "computer-aided manufacturing" (CAD/CAM) model.
