Very close indeed, asX3D() look like that on output:

<IndexedFaceSet coordIndex='0,1,2,-1,3,5,4,-1,6,8,7,-1,9,11,10'>
 <Coordinate point='-594.01205 -192.53033 401.48173,205.44846 ... />
</IndexedFaceSet>

However with X3D a Face could be something else than a triangle,
a square for example... so coordIndex could be something else than
only triplets
