  [in] FLOAT      fTessLevel,
  [in] LPD3DXMESH pMesh
);

Parameters

fTessLevel [in]

Type: FLOAT

Tessellation level. This is the number of vertices introduced between existing vertices. The range of this float parameter is 0 < fTessLevel <= 32.

pMesh [in]

Type: LPD3DXMESH

Resulting tessellated mesh. See ID3DXMesh.

Return value

Type: HRESULT

If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be one of the following: D3DERR_INVALIDCALL, E_OUTOFMEMORY.
