Hi everyone ! I want to create a triangle mesh from a LIDAR pointcloud (around 10 million points) and i want the faces to be created only from the 3 nearest points of itself. Delaunay mesh don’t work for this case, is there a grasshopper module for this? Or another solution ?
The first photo shows the problem of Delaunay Mesh method with the overhanging rocks :
And the second shows how should it be (it’s the pointcloud visualized with cloudcompare)
Thanks, have a nice day !
Indeed, often, CloudCompare is used to turn point clouds into a mesh that you can import into Rhino.
To do this in Rhino or Grasshopper, take a look at the Cockroach plug-in or the older Volvox plug-in.
Yes CloudCompare can create meshes but at this precision it crashes because of the number of points in the cloud (i used plugins->poisson recon), and i need every points to be vertices. Rhino and GH do it but delaunay triangulation renders as first photo. So i’m looking for a command or a software that would take every points and compute triangulation with the three nearest points for creating the mesh.
It looks like you can define how many nearest points are being used in Cockroach - perhaps @Petras_Vestartas can provide more information.
