After you have obtained a context object, you can access the encapsulated objects.
To obtain a pointer to an IDirect3DDevice7 interface, use the ID3DXContext::GetD3DDevice method:
m_pd3dDevice = g_pd3dx->GetD3DDevice(); if (m_pd3dDevice == NULL) return E_FAIL;
To obtain a pointer to an IDirect3D7 interface, use the ID3DXContext::GetD3D method:
m_pd3d = g_pd3dx->GetD3D(); if (m_pd3d == NULL) return E_FAIL;
To obtain a pointer to an IDirectDraw7 interface, use the ID3DXContext::GetDD method:
m_pdd = g_pd3dx->GetDD(); if (m_pdd == NULL) return E_FAIL;
These retrieved interfaces can then be used by your application. For example, the following code uses the retrieved pointer to an IDirect3DDevice7 interface, m_pd3dDevice, to enable dithering, specular effects, lighting, and z-buffer usage.
hr = m_pd3dDevice->SetRenderState(D3DRENDERSTATE_DITHERENABLE, TRUE); hr = m_pd3dDevice->SetRenderState(D3DRENDERSTATE_SPECULARENABLE, TRUE); hr = m_pd3dDevice->SetRenderState(D3DRENDERSTATE_LIGHTING, TRUE); hr = m_pd3dDevice->SetRenderState(D3DRENDERSTATE_ZENABLE, TRUE);
