Meshdiff: A Browser-Based 3D Model Comparison Utility

Meshdiff is a specialized tool designed to visually analyze the differences between two iterations of a 3D model.

This utility operates entirely client-side, meaning your files are processed locally within the browser. No data is uploaded to a server. To function, the application requires JavaScript to be enabled.

Supported File Formats

The tool is compatible with the following 3D standards:

• STL (Stereolithography)
• 3MF (3D Manufacturing Format)
• OBJ (Wavefront Object)

Technical Overview

Feature	Detail
Processing	Local / Client-side
Dependency	JavaScript
Primary Goal	Visual 3D Diffing

The logic of the comparison can be represented by the following mathematical concept: $\Delta \text{Mesh} = \text{Version}_B - \text{Version}_A$

Workflow Process

Usage Checklist

• Enable JavaScript in browser settings.
• Prepare two versions of a 3D file.
• Load files into the interface.

Example Implementation Logic

While the tool is a full application, the conceptual logic for handling the files looks like this:

function compareModels(modelA, modelB) {
  if (!window.JavaScriptEnabled) return "Error";
  return visualDiff(modelA, modelB);
}
