|
|
|
|||
|
|
**命名空间**: `XCEngine::RHI`
|
|||
|
|
|
|||
|
|
**类型**: `class` (abstract)
|
|||
|
|
|
|||
|
|
**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.description.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;
|
|||
|
