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 of parts.

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

All Points Workbench tools can be accessed from the Points menu. Some tools are also available in the Points tools toolbar.

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