Compare three scans

[TheLonelyMountain]

Hi there,

Is there any way that I can compare the differences between three scans of the same object? I have taken scans of fingerprints and wish to know how much, or how little, the differences are between the scans. Is this possible?

Thanks

Well, you can compare the scans two by two at least... And if the same cloud holds the distances (scalar fields - make sure to rename it after each comparison so that it's not overwritten), then you can even compute the difference between the two (with the 'SF Arithmetic' tool)... if that makes any sense ;)

Hi Daniel,

Thank you for getting back to me. Yeah that makes sense. Just to save time, can you tell me how to rename the scalar field for each comparison?

I will let you know how the investigation goes.

Thanks
