# D3D12Device::Initialize

```cpp
bool Initialize(const RHIDeviceDesc& desc) override;
```

初始化 D3D12 设备，建立与图形适配器的连接。

**参数：**
- `desc` - 设备描述符，包含适配器索引、调试选项等配置

**返回：** 成功返回 `true`，失败返回 `false`

**复杂度：** O(1)

**示例：**

```cpp
RHIDeviceDesc desc;
desc.adapterIndex = 0;
desc.enableDebugLayer = true;

D3D12Device* device = new D3D12Device();
if (device->Initialize(desc)) {
    ID3D12Device* nativeDevice = device->GetDevice();
} else {
    delete device;
}
```
