Trying to convert a scan of the inside of building from points to mesh
Posted: Mon Jan 27, 2025 10:34 am
Hi there,
first off: I am new with cloud compare, please bear with me.
I have a 3D scan of the inside of a rather large building. We used the Leica BLK360. I thought the built-in software could automatically transfer the point cloud into a mesh. Someone else did the scanning, I am unsure whether this person failed to do the exporting to a OBJ/STL or not.
Anyway, I am stuck with this point cloud for now. The output is supposed to be used for measurements for different artistic installations, planning basis for the artists etc.
What I did so far:
- calculate normals
- poisson reckon surface reconstruction
When exporting one or multiple (there are 23 individual meshes) and exporting them I can choose between: .bin .fbx. dxf .shp
When exporting to a .fbx files it seems like the output is "solid" but I need it to be hollow.
It feels like I am close but not entirely there. Is there an option to directly export to .stl or .obj? Why is my output solid? Will it be solid when exporting to one of those two formats? If yes: How do I make it hollow?
If you guys want to look at the file, its here: https://drive.google.com/file/d/1jbsUts ... sp=sharing
But be warned, its size is 2.48GB
Kind regards, I appreciate any help!
