A point cloud is a collection of points in 3D space. A point cloud is generally produced by scanning the surface of a solid object.

Introduction

The Points Workbench offers specific tools for working with point clouds. The workbench is still in development.

A point cloud is a collection of points in 3D space. A point cloud is generally produced by scanning the surface of a solid object. The cloud of points can then be used for many purposes including building a mesh for the object, reconstructing the surfaces and solid volumes, reverse engineering, as well as for visualization and quality inspection.

Tools

  • Merge point clouds: Creates a point cloud by combining the points of two or more point clouds.
