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.

目前,点云工作台没有自动处理导入点集的逻辑。

Points workbench icon

簡介

点集工作台是用于 點雲 的一系列特定工具. 它仍在开发中.

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.

工具

这些工具已经可用:

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.

Notes

当然你也可以使用 FreeCAD 的底图工作台并使用底图元件来连接点集。 使用 snap 模式“端点”会保证连接到点集上。
