1. Compute Normals:
Filters > Normals, Curvatures and Orientation > Compute Normals for Point Sets

2. Optimise your point cloud (optional)
Reduce the density of the point cloud by choosing
Filters > Point Set > Point Cloud Simplification

3. Convert the optimised point cloud to a mesh
Filters > Remeshing, Simplification and Reconstruction > Surface Reconstruction: Ball Pivoting
