In their own words
MeshLab
MeshLab is a free desktop system for processing and editing 3D triangular meshes, including unstructured models produced by 3D scanning. Its tools cover editing, cleaning, repair, inspection, rendering, texturing, and conversion. The site describes using it to process raw data from 3D digitization and prepare models for 3D printing. MeshLab supports PTX point-cloud and range-map files, and listed export formats include PLY, STL, OBJ, OFF, WRL, and DXF. It runs on Windows, macOS, and Linux and is distributed under the GPL 3.0 license. PyMeshLab provides a Python interface for loading and saving meshes and applying MeshLab filters; the VCG code can be used in a standalone, large-scale automated processing pipeline. The listed MeshLab 2025.07 release is dated September 9, 2025, and includes ARM64 support on Linux and macOS plus 3MF support. The site points usage questions to Stack Overflow and bug reports to GitHub, with video learning resources for basics, features, scanning workflows, and mesh cleaning.
Structure
Structure builds 3D scanning hardware and software for medical, clinical, and industrial applications. Its technology supports orthotic and prosthetic fitting, wound measurement, surgical planning, and patient monitoring. The Structure Sensor 3 attaches to compatible iPads and provides millimeter depth accuracy for body measurements. Developers can use the Structure SDK for raw depth frames, mesh extraction, foot measurement, and offline licensing; the SDK also supports apps in healthcare, industrial inspection, retail fit-tech, and augmented reality. Structure Capture exports STL, OBJ, and PLY CAD files directly from compatible iPhones and iPads, and includes a Scan Quality Indicator. The SDK detects foot landmarks such as metatarsals, heel point, and arch height. Capture works with specified TrueDepth-enabled iPhones and iPads running iOS 16 or iPadOS 16 or later, and Structure Sensor ST01, ST02, and ST03. A seven-day SDK trial costs nothing. Capture costs $19.99 a month or $199 a year; the Structure Sensor 3 costs $995, paid once. Commercial SDK distribution requires a contract and a quote.
