I''m a newbie at C++ in Direct3D, and this is probably a really stpuid question, but is there some way built into direct3D to automaticaly subdivide faces (like device->Subdivide) or do you have to code subdivision functions your self?

It depends what you mean by "subdivide" - do you mean add more polygons to a mesh to increase its level of tesselation ?

If so, then you could take a look at:

- for offline/load time:
D3DXTessellateNPatches()

- for realtime:
N-patches, higher order surfaces (where supported in hardware!)
