- Rename texture/dtor.md to destructor.md per template spec - Remove duplicate non-hyphenated fence docs (getnativehandle.md, issignaled.md, getcompletedvalue.md) - Fix template field issues: - swap-chain, command-queue: 类型 now uses 'class (abstract)' - sampler: 头文件 now uses full path 'XCEngine/RHI/RHISampler.h' - types: 类型 fixed from 'structs' to 'struct' - enums: 类型 fixed from 'enums' to 'enum class' - Fix include paths in command-queue and pipeline-layout code examples - Create missing constructor/destructor docs for 11 classes: buffer, texture, shader, device, command-list, command-queue, fence, sampler, swap-chain, pipeline-state, pipeline-layout - Update class overview pages to include constructor/destructor entries

# RHIDevice
|
||
|
||
**命名空间**: `XCEngine::RHI`
|
||
|
||
**类型**: `class` (abstract)
|
||
|
||
**头文件**: `XCEngine/RHI/RHIDevice.h`
|
||
|
||
**描述**: RHI 渲染设备抽象接口，代表一个图形设备实例。
|
||
|
||
## 概述
|
||
|
||
`RHIDevice` 是 RHI 模块的核心接口之一，负责创建和管理所有 GPU 资源。每个 RHI 后端（D3D12、OpenGL 等）都需要实现此接口。

## 使用示例
|
||
|
||
```cpp
|
||
// 创建 D3D12 设备
|
||
RHI::RHIDevice* device = RHI::RHIFactory::CreateRHIDevice(RHI::RHIType::D3D12);
|
||
|
||
// 配置设备描述
|
||
RHI::RHIDeviceDesc desc;
|
||
desc.windowHandle = hwnd;
|
||
desc.width = 1280;
|
||
desc.height = 720;
|
||
desc.appName = L"MyApp";
|
||
desc.enableDebugLayer = true;
|
||
|
||
// 初始化设备
|
||
if (device->Initialize(desc)) {
|
||
const RHI::RHICapabilities& caps = device->GetCapabilities();
|
||
if (caps.bSupportsRayTracing) {
|
||
// 设备支持光线追踪
|
||
}
|
||
|
||
const RHI::RHIDeviceInfo& info = device->GetDeviceInfo();
|
||
printf("GPU: %ls\n", info.renderer.c_str());
|
||
|
||
// 创建资源
|
||
RHI::BufferDesc bufferDesc;
|
||
bufferDesc.size = 1024;
|
||
bufferDesc.bufferType = (uint32_t)RHI::BufferType::Vertex;
|
||
RHI::RHIBuffer* buffer = device->CreateBuffer(bufferDesc);
|
||
|
||
device->Shutdown();
|
||
}
|
||
|
||
delete device;
|
||
```
