Meshdiff enables client-side visual STL model comparisons directly in your browser

A new web application called Meshdiff allows designers and engineers to compare different versions of 3D models in STL format directly within a web browser without server-side processing. The tool renders models side-by-side with visual difference highlighting, helping users identify geometric changes between revisions. This client-side approach offers privacy benefits for proprietary designs while eliminating the need to upload sensitive CAD files to external servers. The open-source project demonstrates the capabilities of modern browser technologies in handling complex 3D computations typically requiring desktop applications.
