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 is intended to give you 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. 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.

工具

这些工具已经可用:

• 导入点云: 将会从一个文本文件导入点云的三维点坐标集
• 导出点云: 将会导出点云的三维点坐标集到一个文本文件
• Transform: transforms a point cloud.
• Convert: converts to points.
• 多边型选择：计划中
• Merge: merge several point clouds into one.

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。

限制

目前，点云工作台没有自动处理导入点集的逻辑。 但是通过链接到点云处理库（FreeCAD的Windows版本已经具备该能力），你可以使用 python 命令去进一步处理你的数据，参考讨论 这里 和 这里 (德语子论坛). 另外一个有趣的讨论：这里 (英语帮助论坛).
