Thanks in advance. From the CloudCompare user guide, I know the cells have to be within the "convex hull" of the cloud to be filled, but I think they are- the holes are located in the middle of the cloud on a pretty uniform slope and do not represent any kind of outlying protrusion or I was hoping the interpolate function would be able to fill these holes.

Fill Holes Also, you can close holes manually in several ways by Blender and The closest cases I found was due to the need of filling holes after removing trees. Use a rather large step and select the 'minimum height' as projection type (so as to only keep the ground points). Interpolating the cells only inside the convex hull won't be a problem (the convex hull is unique - The closest cases I found was due to the need of filling holes after removing trees. with the Delaunay triangulation tool, or with the Rasterize tool once again, by using the 'Interpolate' mode for the 'fill empty celles' option). daniel Site Admin Posts: 7817 Joined: Wed Oct 13, 2010 7:34 am daniel Site Admin Posts: 7841 Joined: Wed Oct 13, 2010 7:34 am Location: Grenoble, France You can do this is many softwares, meshlab,cloudcompare etc. daniel Site Admin Posts: 7645 Joined: Wed Oct 13, 2010 7:34 am CloudCompare forum.
