1-how to translate the point cloud by a known distance
2-why cc need 4 points to align two scans (another softwares need 3)
3- transformation in cc is rigid or not rigid??
4- what difference between regestration and align?

1 - see the 'Edit > Apply transformation' tool
2 - I believe you can use only 3 pairs. But it's not robust and can even give strange results in some degenerate cases
3 - rigid
4 - we just use 'registration' for the automatic alignment procedure (ICP) in order to differentiate it with the point pair based alignment procedure.

A rigid transformation preserves the entity shape (and scale - even though CC can change the scale if requested).
