Mesh from point clouds in Meshlab

Question

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 ?

Answer 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.

• Surface Reconstruction: Screened Poisson 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.
