Post by un2jay »

hello,

I'm trying to fill in gaps in a point cloud data. is there a tool i can use in Cloud Compare to do this?
Here is an example of how the hole looks like.

You can use same polyline to trim new pointscloud generated by sampling poission mesh
If you need more control of hole (gap) closing , Blender can help a lot
please check attached bin CC file

Meshing by simple Delaunay (best fitting plane) is possible too
(meshing, sampling ,segmenting then merging into original pointscloud)
