*Texture3D*\
类型：D3D12\_TEX3D\_UAV

一个 [D3D12\_TEX3D\_UAV](/reference/graphics/d3d12/structs/d3d12_tex3d_uav_public) 结构，指定 3D 纹理中可访问的子资源。

## 备注

将无序访问视图描述传递给 [ID3D12Device::CreateUnorderedAccessView](/reference/graphics/d3d12/interfaces/id3d12device/methods/id3d12device_createunorderedaccessview_public) 以创建视图。

## 要求

**头文件：** d3d12\_xs.h 或 d3d12\_x.h\
**库：** d3d12\_xs.lib 或 d3d12\_x.lib\
**支持的平台**：XBOX Series 主机及 XBOX One 系列
