MeshLab: open-source system for processing and editing large 3D triangular meshes from scanning

What it supplies: MeshLab is an open-source, portable and extensible system for processing and editing unstructured large 3D triangular meshes. It targets models from 3D scanning, with tools for editing, cleaning, healing, inspecting, rendering and converting meshes. It is mostly based on the open-source C++ library VCGlib. Useful for: - Clean, heal, inspect and convert scanned 3D meshes interactively. - Experiment interactively with VCGlib algorithms that can also run as a standalone automated pipeline. First action: - Download the latest release for Windows, macOS or Linux from the Releases tab, or try a nightly build from the latest GitHub Actions artifacts. - To build from source, use the build and deploy scripts and the src folder instructions. - Report repeatable bugs through GitHub issues and ask general questions on StackOverflow. Prerequisites and limits: This README gives no system requirements or version number in its own text; build requirements are in the src folder instructions. It says main holds the last release and devel holds features for the next one. - Nightly builds are artifacts of a workflow, not the last release. - Old, unsupported plug-ins are no longer included or built. - The README is an overview; build requirements are in other files. The README states the MeshLab source is released under the GPL licence, with details in LICENSE.txt. It asks users to cite the references it lists. Meshes you process carry their own rights. Written from the README text only. Statements are as the README gives them; nothing was installed or run and no mesh was processed. Based on README text only; the build scripts, src README and LICENSE file were not read. No install or run was made.
