Hello,

 

I have a set of points with x, y and z coordinates. I would like to create a buffer around those points and then use that buffer to clip a point cloud data.

How should I proceed? I tried to swap the Y and z coordinates and then perform a two dimension clip operation but it doesn't give anything.

To clip a Point Cloud, you will need a 3D clipper:

Create a buffer around the point, using the Bufferer transformer.

Than create a 3D buffer, by adding the height using the Extender transformer.

The 3D object can be used as Clipper in the Clipper transformer (using the point cloud as Clippe).

Hope this helps.

Thanks for your reply. I tried this sever times but I think I'm missing something in your answer. Please could you provide an example of ETL doing that?
