问题
I need to reconstruct a surface mesh of a terrain from a dense point cloud.
Is it possible to generate polygonal meshes from point clouds in Meshlab v2016.12?
回答1:
Yes you can!. The process of generating a mesh from a point cloud is called surface reconstruction.
There are several surface reconstruction methods avaliable in meshlab.
Go to Filters -> Remeshing, simplification and Reconstruction
There you can select one of the many choices avaliable. To guide you a little:
Delanuay Triangulation is one of the simplest one and might fit your needs if your surface is not complex.
Screened Poisson Surface Reconstruction is state of the art and it's intended for reconstructing complex surfaces. You might need to tweek some parameters on the pop-up dialog in order to obtain the result you want.
