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.

Can Meshlab determine whether a point is inside a mesh

Meshlab uses vcglib c++ library at its core. I was wondering if Meshlab can check if a point is inside a 3D mesh (polyhedron). I found an article which explains a possible way to determine an internal face. However, the proposed method colors…

MeshLab Quadric Edge Collapse Decimation preserving textures in JavaScript, PHP or Python?

There is a filter in MeshLab that I normally use to decimate (or simplify) 3D models that were 'photogrammetised'; to a lower number of faces (so that they can be viewed faster on mobile client devices). The filter used is the Quadric Edge Collapse…
