Inclination from vertical

[cukiii1312]

Hi,

I have a building and would like to visualize its wall, but with an inclination from the vertical plane. I’m looking for a visualization similar to the one in the attached photo.

Can anyone help me achieve this using CloudCompare or any other open-source software?

Thanks in advance!

So for the second images, you have several choices:
- either it's more the planarity and you can just create a vertical plane (with 'Edit > Plane > Create' for instance), and then computed the distance between the point cloud and this plane (ideally the 'Point-to-primitive distances' - see https://www.cloudcompare.org/doc/wiki/i ... e_Distance)
- or it's also a visualization of how vertical each part of the wall is, and then you'll have to compute the point normals first, and then convert the normals to 'Dip & Dip direction' (see https://www.cloudcompare.org/doc/wiki/i ... ection_SFs). The dip values will give you in degrees the angle to the vertical direction. See https://www.cloudcompare.org/doc/wiki/i ... ection_SFs

And for the first visualization, if you have the 'dip' scalar field, you can project the points as a raster (with the 'Rasterize' tool) and even extract contour lines based on this scalar field. Don't hesitate to share the cloud with me if you need more directions (admin@cloudcompare.org)

But you won't be able to generate the arrows with CloudCompare.

Tnx,

I do it on the first method because I needed just verticality with just wall, not with the normals.
