Volume change calculation

[AbolDH]

Hello
I have two different point clouds from a similar stockpiles that thaken from different times.
Now i wanna calculate the volume change between these two as a pointcloud difference or mesh difference or dem difference.
How can i do that?
Please examine for a amateur user.

That's not easy, but I would use the '2.5D Volume calculation' tool between 2 clouds directly. See https://www.cloudcompare.org/doc/wiki/i ... .5D_Volume

Well, assuming the clouds are 2.5D...
