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. Then the cloud of points can 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.

* [[Points_Structure|Structured point cloud]]: Creates a sorted point cloud from the points of an existing point cloud.
It is also possible to use the tools from the [[Image:Workbench_Draft.svg|24px]] [[Draft Workbench|Draft Workbench]] to connect the points using Draft objects such as [[Image:Draft_Line.svg|24px]] [[Draft Line|Lines]] and [[Image:Draft_BSpline.svg|24px]] [[Draft BSpline|Splines]]. Using the [[Image:Snap_Endpoint.svg|24px]] [[Draft Endpoint|Endpoint]] snapping method will ensure that the tools snap to the imported points.

At the moment the workbench has no automatic routines to deal with the imported points, but the user can use [[Python]] scripting to programmatically process the data.

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.
