M3C2 Distance Direction

[uasghar]

Hey Daniel,

I was wondering what is the direction of the M3C2 distances. I mean are they absolute distances, i.e. sqrt(dx^2 + dy^2 + dz^2)? Can they be split into x, y, and z components?

I used multiscale calculation mode and the orientation for the normals was set to +Z (See attached picture)

I'm actually using it for change detection and want to know the movement in horizontal as well as vertical plane.

Regards,

Umair.

M3C2 outputs signed distances. And they are calculated along the direction of the normal (for each point). The '+Z' option is just to help CC orients the normals (here they will all roughly point upward). If you want purely vertical normals / displacement, then you have to select the 'vertical' option as calculation mode.

And no, you can't split the distance along X, Y and Z in this plugin.
