Mesh not very detailed

[GI_LM_Student]

Hello,

I have scanned a part of a bridge. The following picture shows the pointcloud.

The mesh I wanted to create looks like this:

Can you tell me what I've done false in the settings?
Have you also had problems with meshing detailed pointclouds?

Thanks for your effort

Have you use the Delaunay 2.5D algorithm maybe?

I fear your clouds is definitely not '2.5D' (but more '3D') and you should use the Poisson Reconstruction plugin instead (see https://www.cloudcompare.org/doc/wiki/i ... n_(plugin))
