%description
MeshLab is an open source, portable, and extensible system for the processing
and editing of unstructured large 3D triangular meshes. The source is
released under the GPL license. The system is aimed to help the processing
of the typical not-so-small unstructured models arising in 3D scanning,
providing a set of tools for editing, cleaning, healing, inspecting,
rendering and converting this kind of meshes.
