three.js edge split modifier

This library has been deprecated. It was added to three.js examples, and will only be maintained there.

This package is a geometry modifier for three.js

This modifier takes a geometry as input, and outputs an indexed BufferGeometry with faces split at sharp edges.

Example

We take a flat shaded model:

Using the classic smooth shading doesn't give us the type of result we expect (the sharp edges are smoothed, while they shouldn't):

Using the edge split modifier, we split the faces sharp edges to achieve a better smooth shading:

Browser dependencies

If you want to use this package in a browser, you will need to import three.js along its BufferGeometryUtils example JS file.
