Select 八面体几何中的六角面 THREE.js

Question

我有一个测地线球体 - 它是使用 THREE.OctahedronGeometry 创建的 - 我想将三角形面分组为六边形面，以便可以选择它们。我不知道如何解决这个问题，或者它是否可行。任何见解将不胜感激。

举个例子：

createGeodesicSphere =->
        geometry = new THREE.OctahedronGeometry(200, 3)
        material = new THREE.MeshBasicMaterial({
            color        : 0xFFFFFF,
            shading      : THREE.FlatShading,
            side         : THREE.DoubleSide,
            vertexColors : THREE.FaceColors,
            overdraw     : true 
            })

        # Explode geometry so each face has unique vertices
        explodeModifier = new THREE.ExplodeModifier()
        explodeModifier.modify(geometry)

        geodesicMesh = new THREE.Mesh(geometry , material)
        geodesicFaces = geometry.faces  

        for i in [0..geodesicFaces.length-1]
            geodesicFaces[i].color.setRGB(Math.random(), Math.random(), Math.random())

        geodesicMesh.position.x = 0
        geodesicMesh.position.y = 0
        geodesicMesh.position.z = 0

        scene.add(geodesicMesh)

很可能这是不可能的，但您可以尝试非常接近六边形的 voronoi 图：Spherical Voronoi Tessellation with Java 7: need fix for winding vertices around faces。
