A basic example of simplifying meshes. Open the live demo.
This repository includes different ports of Sven Forstmann's C++ Fast Quadric Mesh Simplification. The table below shows the time to simplify the mni152_2009.mz3 mesh to 10% of its input size.
| Method | Files | Size (kb) | Speed (ms) |
|---|---|---|---|
| nii2mesh | nii2mesh.js | 213 | 650 |
| WASM C++ | a.js | 200 | 800 |
| mXrap | mesh-ta, quadric-mesh-simplification, wrapped_typed_array | 65 | 2100 |
| NiiVue | simplify | 15 | 2150 |
Neuroimaging meshes do not use UV mapping. For simplification of meshes with UV mapping, see this live demo.
You can serve a hot-reloadable web page that allows you to interactively modify the source code.

npm install
npm run dev- This project includes four ports of Sven Forstmann's C++ Fast Quadric Mesh Simplification: a direct web assembly compilation, the mXrap pure JavaScript, the NiiVue team pure JavaScript and the nii2mesh C code compiled as web assembly.
- This repository assumes mesh-based inputs. To convert voxels to meshes and simplify them, see this companion project.
