点云(point cloud)是指透过3D扫瞄仪所取得之资料型式。扫描资料以点的型式记录
点云数据除了具有几何位置以外 点云也是逆向工程中通过仪器测量外表的点数据集合。在电脑动画领域, 皮克斯的玩具总动员3使用了点云技术
A point cloud is a set of data points in some coordinate system.In a three-dimensional coordinate system, these points are usually defined by X, Y, and Z coordinates, and often are intended to represent the external surface of an object.
Point clouds may be created by 3D scanners. These devices measure in an automatic way a large number of points on the surface of an object, and often output a point cloud as a data file. The point cloud represents the set of points that the device has measured.
As the result of a 3D scanning process point clouds are used for many purposes, including to create 3D CAD models for manufactured parts, metrology/quality inspection, and a multitude of visualization, animation, rendering and mass customization applications.2D/3D点云开发资料下载站。
