Hum, indeed, the 'Level' tool is not meant to perform such precise alignment (it's mostly aimed at creating a rough coordinate system, focusing on making the 3 points horizontal).

Maybe you would get better results with the 'Align' tool (point pair picking) if you are able to pick 3 or 4 known ...

Does Global shift only work when importing text files, instead of importing PLY files ? I don't get prompted to global shift the points with PLY files.

As well, I think I may have saw a video on this in which you can create splines from the mesh which I assume you then import into a CAD program for ...

When using 3D scanners they scan at which the orientation of the object is, is it possible to get the object re-oriented at a 0,0,0 in X,Y,Z in cloud compare, this is helpful when reverse engineering, mirroring in CAD programs etc and would this tool be the level tool ?

The issue I have with the ...

Ah, so you are happy with some of the 'bubbles' :-D

In this case, it's tricky... Because the only information we have is how far the triangles are from the closest points. What you could do is sample a lot of points on the raw mesh, segment the resulting cloud with the scissors tool, and ...

Based on the math equation above if those two points existed at 0.400002 and 0.400007 then the offset would be -0.000005. :)

So with Poisson, you generally need to filter the result based on the 'Density' scalar field (see the last section of https://www.cloudcompare.org/doc/wiki/index.php/Poisson_Surface_Reconstruction_(plugin) ).

You can aslo play with the 'boundary' setting to change the behavior of Poisson where no ...

I'm computing the normal's for the mesh below using Triangulation setting. As well I'm using Poisson Surface Reconstruction although this is the results, why does the mesh look like it's a blob, are my Reconstruction settings too high or low ?

In more mathematical terms, if the 2 points are named P and Q :
dX = P.x - Q.x
dXY = sqrt((P.x - Q.x)^2 + (P.y - Q.y)^2)
distance = sqrt((P.x - Q.x)^2 + (P.y - Q.y)^2 + (P.z - Q.z)^2)

In the math sense if R.x = 0.400002 and Q.x = 0.400007 = -0.000005 based on dX = R.x - Q.x ?

Well, that's simply the shift between the points along the X, Y or Z dimension (left column) or in the XY, XZ and ZY planes (right column = 2D distances)


If I understand correctly based on the screen capture, deltaX is the shift between the points, meanwhile deltaXY is the distance between the ...

I'm trying to understand the distance between these two points. I understand the distance is 0.4 between points but the other values I do not understand ?
