subsampling - keeping the sampled points

[JohnDoe]

Do you have something built in to essentially subtract two clouds, outside of doing a cloud to cloud distance calculation? Either as a physical tool or even as a function on the development side?

I have a cloud that I need to process. First step is to sub-sample that cloud, say by 1 inch spacing. What I would like is to be able to sub-sample the cloud and have 2 things result from the process: 1. A sub-sampled cloud containing the 1 inch desired spacing and 2. A cloud containing all points that were deleted or otherwise ignored from the original cloud when sub-sampling occurred.

Nope, you would indeed need to compute the distances and remove the points with a 0 distance...
