threejs-csg (Experimental)
Constructive Solid Geometry for three.js, ES6 + BufferGeometry.
Note: I have stopped working on this for now and there are bugs, although it should work for simple shapes.
Developing
Run npm install then npm start

Usage
const box = new Mesh(new BoxBufferGeometry(0.2, 0.2, 1), material);
box.position.set(0.1, 0.1, 0);
const sphere = new Mesh(new SphereBufferGeometry(0.1), material);
sphere.position.set(0, 0, -0.3);
const sphereB = sphere.clone();
sphereB.position.set(0, 0, 0.3);
const csg = new CSG();
csg.subtract([box, sphere, sphereB]);
// csg.union([box, sphere, sphereB]);
// csg.intersect([box, sphere]);
const resultMesh = csg.toMesh();
TODO
- Only the material from the first mesh is used.
- Vertex colors are ignored.
- Make it faster!!
