按索引删除面孔-three.js

Question

我得到了一个基于不同面的几何形状的网格。

我想在运行时从该几何图形中删除一个面。

可以使用three.js吗？

let mesh = new THREE.Mesh(
  geometry,
  textures
);
mesh.name = "map"
scene.add(mesh)

// runtime function should e.g. remove face with index 15
faceToDelete = {
  distance: 1000,
  face: Tb {a: 10756, b: 10758, c: 10757, normal: n, vertexNormals: 
  Array(3)},
  faceIndex: 15,
  object: ra {name: "map", type: "Mesh"},
  point: n {x: 87.01836565006928, y: 50, z: -245.99743779172834},
  uv: C {x: 0.3701836565006929, y: 0.9799871889586418},
} // (copied from console)

delete faceToDelete // does not seems to work without producing deep errors

有没有一种方法可以实现我想要的？
