Meshdiff makes two STL models argue in the browser
A client-side visual comparator turns the familiar code-review idea into a tool for inspecting changed 3D geometry.
Meshdiff compares two STL files visually in a browser, without sending the models to a server. For makers and reviewers, that turns a hard question—what changed in this print?—into a direct inspection task.
A diff for shape instead of lines
Meshdiff is a browser-based tool for visually comparing two STL versions on the client side. STL files describe meshes rather than source lines, so a conventional text diff can miss the change a designer or fabricator actually needs to see.
Local processing is part of the feature
Keeping the comparison in the browser is useful when a model is sensitive or simply too inconvenient to upload. The project’s concrete contribution is not another 3D viewer: it makes revision review native to the object being revised.
