FTexture2DRHIRef TextureTargetRHI的销毁，都是直接调用SafeRelease()将自己置空

TextureTargetRHI.SafeRelease();

D3D11下VertexShader用法

const D3D11_INPUT_ELEMENT_DESC inputLayout[3] = {
    { "POSITION", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 0, D3D11_INPUT_PER_VERTEX_DATA, 0 },
    { "NORMAL", 0, DXGI_FORMAT_R32G32B32_FLOAT, 1, 0, D3D11_INPUT_PER_VERTEX_DATA, 0 },
    { "TEXCOORD", 0, DXGI_FORMAT_R32G32_FLOAT, 2, 0, D3D11_INPUT_PER_VERTEX_DATA, 0 }
};
ComPtr<ID3DBlob> vsBlob;
HR(CreateShaderFromFile(L"HLSL\\Triangle_VS.cso", L"HLSL\\Triangle_VS.hlsl", "VS", "vs_5_0", vsBlob.ReleaseAndGetAddressOf()));
HR(deviceContext->CreateVertexShader(vsBlob->GetBufferPointer(), vsBlob->GetBufferSize(), nullptr, vertexShader.GetAddressOf()));  // 创建顶点着色器 ComPtr<ID3D11VertexShader> vertexShader
HR(deviceContext->CreateInputLayout(inputLayout, ARRAYSIZE(inputLayout),vsBlob->GetBufferPointer(), vsBlob->GetBufferSize(), vertexLayout.GetAddressOf())); // 创建并绑定顶点布局  //ComPtr<ID3D11InputLayout> vertexLayout

// 设置图元类型，设定输入布局
deviceContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST);
deviceContext->IASetInputLayout(vertexLayout.Get());
// 将顶点着色器绑定到渲染管线
deviceContext->VSSetShader(vertexShader.Get(), nullptr, 0);

PixelShader

D3D11下PixelShader用法

// 创建像素着色器
ComPtr<ID3DBlob> psBlob;
HR(CreateShaderFromFile(L"HLSL\\Triangle_PS.cso", L"HLSL\\Triangle_PS.hlsl", "PS", "ps_5_0", psBlob.ReleaseAndGetAddressOf()));
HR(deviceContext->CreatePixelShader(psBlob->GetBufferPointer(), psBlob->GetBufferSize(), nullptr, pixelShader.GetAddressOf())); // ComPtr<ID3D11PixelShader> pixelShader

// 将着色器绑定到渲染管线
deviceContext->PSSetShader(pixelShader.Get(), nullptr, 0);

ComputeShader

D3D11下ComputeShader用法

ComPtr<ID3DBlob> blob;
HR(CreateShaderFromFile(L"HLSL\\TextureMul_R32G32B32A32_CS.cso", L"HLSL\\TextureMul_R32G32B32A32_CS.hlsl", "CS", "cs_5_0", blob.GetAddressOf()));
HR(m_pd3dDevice->CreateComputeShader(blob->GetBufferPointer(), blob->GetBufferSize(), nullptr, computeShader.GetAddressOf()));// ComPtr<ID3D11ComputeShader> computeShader;

m_pd3dImmediateContext->CSSetShader(computeShader.Get(), nullptr, 0);

VertexDeclaration

从VertexFactory --》VertexDeclaration

class FD3D11VertexDeclaration : public FRHIVertexDeclaration
{
public:
    /** Elements of the vertex declaration. */
    FD3D11VertexElements VertexElements; // typedef TArray<D3D11_INPUT_ELEMENT_DESC,TFixedAllocator<MaxVertexElementCount> > FD3D11VertexElements;   // MaxVertexElementCount为16

    uint16 StreamStrides[MaxVertexElementCount];  // 

    /** Initialization constructor. */
    explicit FD3D11VertexDeclaration(const FD3D11VertexElements& InElements, const uint16* InStrides)
        : VertexElements(InElements)
    {
        FMemory::Memcpy(StreamStrides, InStrides, sizeof(StreamStrides));
    }
};

注1：FD3D11VertexElements VertexElements用于创建输入布局

注2：uint16 StreamStrides[MaxVertexElementCount]是各顶点缓冲区的Stride偏移，会透传给FBoundShaderStateInput BoundShaderState的StreamStrides成员变量

 

D3D11多顶点缓冲区输入

在输入装配阶段中提供了16个输入槽（Slot），这意味着我们最多可以同时绑定16个顶点缓冲区作为输入。

现在假定着色器需要使用的顶点结构为：

索引	顶点位置	顶点法向量	顶点UV
0	P1	N1	T0
1	P2	N2	T1
2	P3	N3	T2

示意图：
