I have experienced the square tiling patterns on curved surfaces in the past when comparing various scanners, in my case I was able to determine that one sensors resolution combined with multiple passes/positions would cause local flat spots which were difficult to visualize on a single cloud/sensor...

One way to help the normal calculation would be to segment each room into individual clouds and then calculate the normals with preferred orientation of Barycenter which would have align normals towards the center of the room or out of it depending on + or - Barycenter choice.

I'll submit a fix today, just need to add closePolyLine(); to the escape key case Qt::Key_Escape: closePolyLine(); cancelButton->click(); return; This fixed the issue as far as I can tell. or just directly release the mouse inside the reset function void ccGraphicalSegmentationTool::reset() { if (m_...

Ah I was able to reproduce, first test I thought you meant to right click before esc.

I'll look into it.

I've tested with both clouds and meshes and am not able to reproduce, does this always happen with a specific cloud or mesh? If so can you share so we can track down the issue?

I'm not sure off the top of my head why there would be a missing dll for install but, out of curiosity can you try the 2.12 Alpha. (even though it is called alpha, it is pretty mature at this point).

//point to plane distance: d = (a0*x+a1*y+a2*z - a3) / sqrt(a0^2+a1^2+a2^2) **USED in Cloud Compare pointtoplanedist.JPG **USED in linked website main difference is (a0*x+a1*y+a2*z - a3) vs abs( (a0*x+a1*y+a2*z + a3) ) So it appears it is related to the sign of the const value pointtoplanedistExampl...

I would specifically use the point to primitive distance calculation rather than the point to mesh calculation (it should work totally fine, but on certain edge cases the mesh based calculations can have an incorrect sign). also with the point to primitive calculation you can choose whether or not t...
