MeshCrunch — 3D Mesh Simplifier and LOD Generator

• 3D mesh simplification / polygon decimation: Reduce triangle count with quadric-error decimation while preserving the silhouette. Compare original and optimized side by side, with exact triangle and file-size savings.

• Level-of-detail (LOD) chain generation: Turn one high-poly asset into a full level-of-detail ladder in a single request, each level decimated from the original. Download individually or as one ZIP with a manifest.

• In-browser 3D model preview: Inspect a model with orbit controls, grid and wireframe, drawn by your own browser. No account required.

• 3D mesh inspection and QA reporting: Find what is wrong with a model — non-manifold edges, holes, winding, missing UVs — and whether it fits the platform you are shipping to. Exports a one-page QA report.

• Watertight surface reconstruction: Wrap a new closed surface around a model the decimator cannot fix — holes, self-intersections, loose triangles.

• Turntable GIF and MP4 export: Turn a model into a rotating GIF or MP4, with presets and a live preview. Rendered on your machine, so it costs no processing allowance.

• 3D format conversion: Convert between OBJ, STL, PLY, OFF and GLB. No account for your first conversion, and your original stays untouched.

• Backend-rendered asset thumbnails

MeshCrunch simplifies meshes and generates LOD chains, writing the result as OBJ, STL, GLB, PLY or OFF — so your games, web scenes, and XR apps load in a fraction of the time. It runs entirely in the browser and accepts multiple 3D file formats. Built for game, web, and XR pipelines.

How it works:

1. Upload once: Drag in your model — up to 50 MB per file free, and more on a paid plan. It goes straight to private storage and becomes a reusable asset in your library.

2. Optimize: Simplify it or generate an LOD chain from the same workspace. Processing runs on our servers, so a refresh never loses it.

3. Come back: Inspect the result, download it, and re-crunch the same source later with different settings. Files are kept 7 days on a free account. Without one they are deleted after 24 hours, unless you sign in — that claims them automatically.

Three ways to use it:

• Studio: The visual workspace. Upload once, inspect the model, choose an operation, compare the result against the original without the camera moving, and download it.

• REST API: The programmatic surface. Create a key, upload straight to storage, submit a job and poll it — from a script, a build step, or an asset pipeline that never opens a browser.

• MCP: The agent-facing surface. Connect an AI client such as Claude and ask it to optimize assets already in your account — it can price an operation, run it, and read the result.
