meshlab

TLDR

Start MeshLab GUI

$ meshlab

Open mesh file

$ meshlab [model.stl]

Convert mesh format

$ meshlabserver -i [input.obj] -o [output.stl]

Apply filter script

$ meshlabserver -i [input.ply] -o [output.ply] -s [filters.mlx]

Batch process files

SYNOPSIS

meshlab [files...]
meshlabserver -i input -o output [options]

MeshLab is an open-source system for processing and editing 3D triangular meshes. It provides tools for cleaning, healing, inspecting, rendering, and converting meshes.
meshlabserver is the command-line version for batch processing.

PARAMETERS

-l file

Log file.

-om mask

Output mask options.

SUPPORTED FORMATS

$ Input: STL, OBJ, PLY, OFF, 3DS, PTX, PTS
