详细描述

把 CPU RGBA8 Texture 上传为默认堆资源，并提供每材质使用的 SRV。

构造及析构函数说明

DX12TextureManager()

DX12TextureManager::DX12TextureManager ( DX12Render * render )

explicit

成员函数说明

Bind()

void DX12TextureManager::Bind

(

)

const

绑定唯一的 CBV/SRV/UAV Shader-visible 堆。

GetGPUDescriptor()

D3D12_GPU_DESCRIPTOR_HANDLE DX12TextureManager::GetGPUDescriptor

(

ResourceRef< BaseTexture >

texture

)

const

返回指定纹理的 GPU SRV；未知资源引用返回零描述符句柄。

Init()

void DX12TextureManager::Init

(

)

上传 ResourceManager 中的全部纹理并创建稳定 SRV 索引。
