怎么改变物体坐标

如何改变物体坐标
原来我是使用这种方法来转换一个物体的位置的

但是我发现camera移动的时候这个物体就没有移动，那怎么做才能只改变它的物体坐标呢？

C/C++ code

void CALLBACK OnFrameRender( IDirect3DDevice9* pd3dDevice, double fTime, float fElapsedTime, void* pUserContext ){    HRESULT hr;        pd3dDevice->Clear( 0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, D3DCOLOR_XRGB( 0,255,255 ), 1.0f, 0 );        pd3dDevice->SetRenderState(D3DRS_LIGHTING, false);         if (SUCCEEDED(pd3dDevice->BeginScene()))        {            model.Render(pd3dDevice);            pd3dDevice->SetTransform(D3DTS_WORLD, &m) ;            room.Render(pd3dDevice);//*****************************************************            D3DXMATRIX world = *MyCamera.GetWorldMatrix() ;            pd3dDevice->SetTransform(D3DTS_WORLD, &world) ;            // Set view matrix            D3DXMATRIX view  = *MyCamera.GetViewMatrix() ;            pd3dDevice->SetTransform(D3DTS_VIEW, &view) ;            // Set projection matrix            D3DXMATRIX proj  = *MyCamera.GetProjMatrix() ;            pd3dDevice->SetTransform(D3DTS_PROJECTION, &proj) ;//*****************************************************            pd3dDevice->EndScene();        }}void CALLBACK OnFrameMove( double fTime, float fElapsedTime, void* pUserContext ){    MyCamera.FrameMove( fElapsedTime );    D3DXMatrixRotationY( &m, 45 );    }
