#includeThis code example creates a Direct3D device with software vertex processing and a windowed display mode. It then clears the screen with a blue color and renders a scene before presenting it to the screen. The library used in this example is Direct3D 9.#pragma comment (lib, "d3d9.lib") int main() { LPDIRECT3D9 pD3D = NULL; LPDIRECT3DDEVICE9 pd3dDevice = NULL; pD3D = Direct3DCreate9(D3D_SDK_VERSION); // Specify device presentation parameters D3DPRESENT_PARAMETERS d3dpp; ZeroMemory(&d3dpp, sizeof(d3dpp)); d3dpp.Windowed = TRUE; d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD; d3dpp.BackBufferFormat = D3DFMT_UNKNOWN; // Create the Direct3D device HRESULT hr = pD3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &pd3dDevice); if (FAILED(hr)) { MessageBox(hWnd, "Failed to create Direct3D device!", "Error", MB_OK | MB_ICONERROR); return 0; } // Use the Direct3D device for rendering pd3dDevice->Clear(0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, D3DCOLOR_XRGB(0, 0, 255), 1.0f, 0); pd3dDevice->BeginScene(); // Render scene pd3dDevice->EndScene(); pd3dDevice->Present(NULL, NULL, NULL, NULL); // Clean up pd3dDevice->Release(); pD3D->Release(); return 0; }
