PBG of gyroid structure

Dear all,

I am trying to model the photonic bandgap of a gyroid (Ia3d) structure 
using MPB. I was wondering if this was possible using MPB given the 
surface is continuous and not discrete and would appreciwate any help in 
setting up the unit cell.

Or is MEEP more suited to this. I have written a code that can import 
any arbitrary geometry (2D/3D) into MEEP.

Many thanks,
Vinod


PS>  The gyroid surface divides space into two separate, continuous 
networks.

Each network consists of 3-fold connectors.
      NETWORK ONE
              1/8, 1/8, 1/8
              connected to ->     -1/8, 1/8, 3/8
                              1/8, 3/8, -1/8
                              3/8, -1/8, 1/8
              Translations of 1/2,1/2,1/2 + periodic translations 
generates 8 connectors per unit cell.
     NETWORK TWO
              3/8, 3/8, 3/8
              connected to ->
                              3/8, 1/8, 5/8
                              5/8, 3/8, 1/8
                              1/8, 5/8, 3/8
              Translations of 1/2, 1/2, 1/2 + periodic translations 
generates 8 connectors per unit cell.
