MeshLab is an open source program for editing 3D triangle mesh files in various formats. It is used in 3D scanning and virtual reality applications.

MeshLab is a open source desktop program for editing 3-D triangle mesh files in various formats used in 3-D scanning and virtual reality. It was originally developed as a didactical experiment at the University of Pisa and is actively maintained at the Visual Computing Lab of the Italian National Research Council.

Windows, Linux, and Mac OS X versions are available at the MeshLab official site.

Its capabilities include importing and exporting 3-D triangular mesh files in various formats, mesh visualization, and mesh editing functions such as cleaning, painting, remeshing, selecting and deleting parts of the mesh, and colorization.
