Select Hexagonal Face in OctahedronGeometry THREE.js

Question

I have a geodesic sphere - which was created using THREE.OctahedronGeometry - I would like to group triangular faces into hexagonal faces, so they can be selected. I'm at a loss about how to approach this problem or if it's even feasible. Any insight would be appreciated.

Here's an example: enter image description here

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)

Most likely its not possible but you can try a voronoi diagram which is very close to a hexagon:Spherical Voronoi Tessellation with Java 7: need fix for winding vertices around faces.

Thanks for the pointer. I'm going to look into this - I'll mark your answer correct if it pans out. – Foreign Object Mar 20 '15 at 21:57
@ForeignObject: I think a hexagon tiling would be not equal. – Micromega Mar 20 '15 at 22:00
I agree, I'm pretty sure it's not possible to cover a sphere in hexagons of equal size. – Foreign Object Mar 20 '15 at 22:02
@ForeignObject:If my answer is helpful please consider to accept it and/or upvote it! Thank you! – Micromega Mar 21 '15 at 14:47
Thanks, after doing more research your answer helped to point me in a better direction. – Foreign Object Mar 23 '15 at 18:55
