# RHIPipelineLayout
|
||
|
||
**命名空间**: `XCEngine::RHI`
|
||
|
||
**类型**: `class` (abstract)
|
||
|
||
**头文件**: `XCEngine/RHI/RHIPipelineLayout.h`
|
||
|
||
**描述**: GPU 渲染管线布局抽象接口，用于定义着色器资源的绑定布局。
|
||
|
||
## 概述
|
||
|
||
`RHIPipelineLayout` 是 RHI（Rendering Hardware Interface）模块的核心类之一，负责描述GPU渲染管线中着色器资源的绑定布局。它定义了管线中使用的常量缓冲区、纹理采样器和无序访问视图的数量和配置。作为抽象基类，`RHIPipelineLayout` 需要由具体的图形API实现（如 D3D12、OpenGL）提供具体实现。

|
||
| 方法 | 描述 |
|
||
|------|------|
|
||
| [`Initialize`](initialize.md) | 初始化管线布局 |
|
||
| [`Shutdown`](shutdown.md) | 关闭并释放资源 |
|
||
| [`GetNativeHandle`](get-native-handle.md) | 获取原生句柄 |
|
||
|
||
## 使用示例
|
||
|
||
```cpp
|
||
#include "RHI/RHIPipelineLayout.h"
|
||
#include "RHI/RHIDevice.h"
|
||
|
||
// 创建设备后创建管线布局
|
||
RHIPipelineLayoutDesc layoutDesc;
|
||
layoutDesc.constantBufferCount = 2;
|
||
layoutDesc.textureCount = 4;
|
||
layoutDesc.samplerCount = 2;
|
||
layoutDesc.uavCount = 1;
|
||
|
||
RHIPipelineLayout* pipelineLayout = device->CreatePipelineLayout(layoutDesc);
|
||
if (pipelineLayout->Initialize(layoutDesc)) {
|
||
// 管线布局初始化成功
|
||
void* nativeHandle = pipelineLayout->GetNativeHandle();
|
||
|
||
// 使用原生句柄进行绑定...
|
||
|
||
pipelineLayout->Shutdown();
|
||
}
|
||
delete pipelineLayout;
|
||
```
