# D3D12Common::GetGPUDescriptorHandle
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
inline D3D12_GPU_DESCRIPTOR_HANDLE GetGPUDescriptorHandle(
|
||
|
|
D3D12_GPU_DESCRIPTOR_HANDLE baseHandle,
|
||
|
|
UINT offsetInDescriptors,
|
||
|
|
UINT descriptorSize
|
||
|
|
)
|
||

**参数：**
|
||
|
|
- `baseHandle` - 基础描述符句柄
|
||
|
|
- `offsetInDescriptors` - 描述符偏移数量
|
||
|
|
- `descriptorSize` - 单个描述符大小（字节）
|
||
|
|
|
||
|
|
**返回：** 偏移后的 GPU 描述符句柄
|
||
|
|
|
||
|

**线程安全：** ✅（纯函数）
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
D3D12_GPU_DESCRIPTOR_HANDLE srvHandle = GetGPUDescriptorHandle(
|
||
|
|
heapStartHandle,
|
||
|
|
5, // 第6个描述符
|
||
|
|
srvDescriptorSize
|
||

|
||
|
|
```
