Low Poly Mesh from LIDAR point cloud
Posted: Sun Jul 19, 2020 11:50 am
Hello there,
I've downloaded some LIDAR pointclouds from earth surface for my latest project. Resolution of those scans is 1 point/meter. The total size of those pointclouds is about 3.5/3 km.
Now I need meshes from those pointclouds, to export as .fbx, the parts I do need high res from are about 1.5/0.6 km area in the middle. The rest outside of that only needs lower polys/resolution. (depicted in attacked picture, inside orange needs high resolution mesh, outside lower)
I tried creating meshes using the "Delauney 2.5D (XY)" function. but could only make higher resolution meshes. The fbx would then be 2GB.
Is there a way to create lower resolution triangulation meshes than points in the cloud? E.G.: 200 meter triangle sides or the likes?
Thanks already!
