How can i simply split a pointcloud. 

And what is the question?

i want to split them 

One way to do this:

• HullAccumulator to generate polygons for the different parts.
• Counter to generate sub id for each polygon.
• Clipper to clip the pointcloud with the polygons. Merge count attribute to clipped polygons.
• FeatureWriter to write each splitted pointcloud.

im afraid im not on the level to be able to understand how to modify these Transformers, any tips?
