MeshLab (32-bit)

From MeshLab: MeshLab helps processing of the typical large unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering, and converting this kind of meshes. The system is heavily based on the VCG library developed at the Visual Computing Lab of ISTI - CNR, for all the core mesh processing tasks. Features include interactive selection and deletion of portion of the mesh, painting interface for selecting, smoothing and coloring meshes, import formats PLY, STL, OFF, OBJ, 3DS, COLLADA, PTX, V3D, PTS, APTS, XYZ, GTS, TRI, ASC, X3D, X3DV, VRML, and ALN, export formats PLY, STL, OFF, OBJ, 3DS, COLLADA, VRML, DXF, GTS, U3D, IDTF, and X3D, removal of duplicated, unreferenced vertices, null faces, and small isolated components, re-meshing filters, various Colorization or Inspection filters, interactive Mesh Painting, measuring tool, slicing tool, 3D Scanning tools, and large rendering (up to 16k x 16k) for high quality printing.
