I don't see a documented interface for this, but you can find the patch object produced by the show method and then get the faces and vertices from the patch object. Just be aware that digging into the internals of a visualization like this might not work exactly the same way in a future release.

H = spiralRectangular;
show(H)
p = findobj(gca,'type','patch')
p(2)

ans = 

  Patch with properties:

    FaceColor: [0.8745 0.7255 0.2275]
    FaceAlpha: 1
    EdgeColor: 'none'
    LineStyle: '-'
        Faces: [30×3 double]
     Vertices: [32×3 double]
