PointCloud PickBox and export to csv

Hi there,

I'm french, so, I hope, you'll excuse my english :-)

I'm trying to developp a module to select a region from a pointclound instance and export all the points in my selection to a csv file.

I found Code Region: PickBox wich use CreateMultiPlaneFilter to highlight points selected.

I've got 2 questions :

1. if i use the GetPoints function, does the function extracts points from my filter?
2. when I change the view range or the offset delimitation of my view, I can control the visibility of my cloud. Does the getPoints takes into account the points masked or not?

I hope I make myself understood...

1000 thx :-)
