Download MeshLab – Free 3D Mesh Processing and Editing Software

MeshLab is a free, open-source 3D mesh processing system developed by the ISTI-CNR research center in Italy. It is designed for processing, editing, cleaning, healing, inspecting, rendering, and converting 3D triangular meshes — making it an essential tool for researchers, engineers, archaeologists, and 3D artists working with scanned or generated point cloud data.

MeshLab supports an extensive range of 3D file formats including OBJ, STL, PLY, OFF, COLLADA, and many more. Its rich library of filters covers everything from mesh simplification and noise removal to surface reconstruction, texture mapping, and curvature analysis. The application also handles large point clouds from photogrammetry and 3D scanner outputs with ease.

MeshLab is the tool of choice for post-processing 3D scan data, preparing models for 3D printing, and scientific visualization. It is trusted by universities, research institutions, and 3D professionals worldwide.

Key Features

• Supports OBJ, STL, PLY, OFF, COLLADA, and dozens of other 3D mesh formats
• Mesh cleaning filters to remove duplicate vertices, non-manifold edges, and noise
• Surface reconstruction from point clouds using Poisson and Ball Pivoting algorithms
• Mesh simplification and decimation to reduce polygon count while preserving shape
• Texture mapping, UV unwrapping, and color per-vertex painting tools
• Measurement and analysis tools: curvature, distances, section cuts, and bounding box
• Scripting support via Python and MeshLab XML filter scripts for batch processing
