在D3D12中,我怎样画方形？以下代码只能绘制第一个三角形.

为什么D3D12中没有D3D12_PRIMITIVE_TOPOLOGY_TYPE_TRIANGLELIST？TRIANGLELIST有什么选择吗？或者有没有办法直接画广场？

            D3D12_GRAPHICS_PIPELINE_STATE_DESC psoDesc = {};
            psoDesc.InputLayout = { inputElementDescs, _countof(inputElementDescs) };
            psoDesc.pRootSignature = g_rootSignature.Get();
            psoDesc.VS = CD3DX12_SHADER_BYTECODE(vertexShader.Get());
            psoDesc.PS = CD3DX12_SHADER_BYTECODE(pixelShader.Get());
            psoDesc.RasterizerState = CD3DX12_RASTERIZER_DESC(D3D12_DEFAULT);
            psoDesc.BlendState = CD3DX12_BLEND_DESC(D3D12_DEFAULT);
            psoDesc.DepthStencilState.DepthEnable = FALSE;
            psoDesc.DepthStencilState.StencilEnable = FALSE;
            psoDesc.SampleMask = UINT_MAX;
            psoDesc.PrimitiveTopologyType = D3D12_PRIMITIVE_TOPOLOGY_TYPE_TRIANGLE;
            psoDesc.NumRenderTargets = 1;
            psoDesc.RTVFormats[0] = DXGI_FORMAT_R8G8B8A8_UNORM;
            psoDesc.SampleDesc.Count = 1;
            if (SUCCEEDED(g_pd3dDevice->CreateGraphicsPipelineState(&psoDesc, IID_PPV_ARGS(&g_pipelineState))))
            {
