I am trying to separate land, tree and building in an e57 file(originally LAZ file, transformed through CloudCompare).
And I have two questions regarding it.
1 I opened the e57 file directly in Rhino.
I exploded the model to separate the points.
But the points look much larger after the explosion.
I am not sure if it is the right way to do this?
Before the explosion
2 After the points picking and separation, I want to turn the land points into a mesh.
I used the patch function by following the tutorial.
Because there are a lot of points, I set the patch as following image
Why you do not estimate pointcloud normals and mesh it using Poisson surface reconstruction in CloudCompare? Poisson will create closed mesh, so output Distance Field to crop correctly.
Using Pointcloud normals and Poisson surface reconstruction in CloudCompare is much easier and have a better effect than doing it in Rhino!
Thank you for this!!
I still meet the problem of splitting mesh in Rhino. I cannot separate the tree part from the land and building part. Could you help with this?
Also in Cloudcompare use SOR filter, to discretize cloud into components, it would split the cloud into this landscape part and separate small elements.
For rhino, there is Volvox and other plugins, it is mainly , loading, cropping, section, distance functions. However, Volvox has command-line interface where you can call cloudcompare.
