Hello,
I am wondering if there is a possibility to intersect several point clouds. To be more precisely, I have point clouds acquired on different dates and by different methods (structure from motion and TLS). I registered them and cut out some areas I don't need for further calculations. Now if I add a new pointcloud and register it, I want to have the same boundaries as the others have. Is there any way I can do this in CC?
Thanks in advance,
Georg

Re: Intersect clouds
Not easily at least.
You could do something equivalent with the 'Edit > Crop' method (specifying always the same box for all clouds). But it will only work for a box-shaped area.
If you need to use a non regular polygon to segment the cloud you can also use the '-CROP_2D' option of the command line mode (see the wiki) to crop the cloud (in a single direction though). To help you define the polygon you can use the point list picking tool, then export the list of point as a text file.

Works well with -CROP2D...
Thank you very much!
