javascript - Select Hexagonal Face in OctahedronGeometry THREE.js -

i have geodesic sphere - created using three.octahedrongeometry - group triangular faces hexagonal faces, can selected. i'm @ loss how approach problem or if it's feasible. insight appreciated.

here's example:

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 each face has unique vertices         explodemodifier = new three.explodemodifier()         explodemodifier.modify(geometry)          geodesicmesh = new three.mesh(geometry , material)         geodesicfaces = geometry.faces            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 not possible can try voronoi diagram close hexagon:spherical voronoi tessellation java 7: need fix winding vertices around faces.
