MeshLab – Free, open-source, portable and extensible 3D geometry processor

MeshLab is a free, open-source, portable and extensible three-dimensional geometry (3D meshes) processing system that was developed by the ISTI-CNR research center from Italy, and first published in late 2005. It is mainly used to perform interactive processing and unstructured editing to three-dimensional triangular meshes on Windows, Linux and Mac OS X, and has become popular in many technical fields of 3D development & data handling.
