WireFrame-Modus aktivieren?

[sdffds]

D3D11_RASTERIZER_DESC RSWireFrameDesc;
	RSWireFrameDesc.FillMode = D3D11_FILL_WIREFRAME;
	g_pd3dDevice->CreateRasterizerState(&RSWireFrameDesc, &pRSWireFrame);

g_pImmediateContext->RSSetState(pRSWireFrame);

Warum aktiviert das nicht den Wireframemodus?

so funzt es:

D3D11_RASTERIZER_DESC descRast;
    ZeroMemory( &descRast, sizeof(descRast) );
    descRast.CullMode = D3D11_CULL_NONE;
    descRast.FillMode = D3D11_FILL_WIREFRAME;
	V_RETURN( g_pd3dDevice->CreateRasterizerState( &descRast, &pRSWireFrame ) );
