CloudCompare forum

When I applied Poisson Surface Reconstruction, the surface are created even where there is no point. The black area shows point clouds. Why are surfaces created even where there is no point cloud? Why the surface converges to a rounded shape? Could you recommend an article or where should I get the ...

I am sorry that my question wasn’t clear. Using Cloud Compare, I calculated the normals from my cloud points. I used this options in the calculations “(edit>normals>compute>Loacalsurface=Plane,Octree radius=auto,Orientation=+Z)”. I am looking for the theories used in the calculations of normals in t...

I calculated normals from my cloud points (edit>normals>compute>Loacalsurface=Plane,Octree radius=auto,Orientation=+Z)
Could you tell me how to calculate normals within the selected radius ?
What papers shoul I read?

Thank you for answering my question. I tried Poisson Reconstruction plugin as you said(1.compute +Z normals 2.plugin/poissonRecon (Leave everything at default.)), but the surface was not created correctly(the picture is attached below). I want to create only a cross section along the point cloud.(I ...

I am now working to generate a surface from a set of points (cloud data) (the shape of the clustered points is attached below). When I tried using `edit/mesh/Delaunay2.5D`, I can select maximum edge size but cannot select minimum size of the mesh. The distances between my cloud points are very small...
