DirectX 11 镶嵌着色器不工作

如何解决DirectX 11 镶嵌着色器不工作

我的镶嵌着色器有问题。它在我不使用 Hull Shader 或 Domain Shader 时呈现。只是普通的顶点和像素着色器工作正常。这是我的 VS 和 PS 着色器：

VOut VShader(float4 position : POSITION,float4 color : COLOR) 
{
VOut output;
output.position = mul(world,position);
output.color = color;
return output;  
}
float4 PShader(float4 position : SV_POSITION,float4 color : COLOR) : SV_TARGET
{
return color;
}

我正在使用正交投影将像素映射到它们的原始位置。这是有问题的着色器。其中输入 float3 个顶点和 float4 个颜色。

cbuffer cbPerFrame : register(b0) {
    matrix world; };

struct VS_CONTROL_POINT_INPUT {
    float3 vPosition        : POSITION; };

struct VS_CONTROL_POINT_OUTPUT {
    float3 vPosition        : POSITION; };

struct HS_CONSTANT_DATA_OUTPUT {
    float Edges[3]          : SV_TessFactor;
    float Inside            : SV_InsideTessFactor; };

struct HS_OUTPUT {
    float3 vPosition           : POSITION; };

HS_CONSTANT_DATA_OUTPUT ConstantHS(InputPatch<VS_CONTROL_POINT_OUTPUT,3> ip,uint PatchID : SV_PrimitiveID) {
    HS_CONSTANT_DATA_OUTPUT Output;
    Output.Edges[0] = Output.Edges[1] = Output.Edges[2] = 4;
    Output.Inside = 4;
    return Output; }

   [domain("tri")]
   [partitioning("integer")]
   [outputtopology("triangle_cw")]
   [outputcontrolpoints(3)]
   [patchconstantfunc("ConstantHS")]

HS_OUTPUT HShader(InputPatch<VS_CONTROL_POINT_OUTPUT,3> p,uint i : SV_OutputControlPointID,uint PatchID : SV_PrimitiveID)

 {
        HS_OUTPUT Output;
        Output.vPosition = p[i].vPosition;
        return Output;
 }

struct DS_OUTPUT {
    float4 vPosition        : SV_POSITION; };

[domain("tri")]
 DS_OUTPUT DShader(HS_CONSTANT_DATA_OUTPUT input,float3 UVW : SV_DomainLocation,const OutputPatch<HS_OUTPUT,3> quad) {
        DS_OUTPUT Output;
        float3 finalPos = UVW.x * quad[0].vPosition + UVW.y * quad[1].vPosition + UVW.z * quad[2].vPosition;
        Output.vPosition = mul(world,float4(finalPos,1));
        return Output; }

VS_CONTROL_POINT_OUTPUT VShader(VS_CONTROL_POINT_INPUT Input) {
    VS_CONTROL_POINT_OUTPUT Output;
    Output.vPosition = Input.vPosition;
    return Output; }

float4 PShader(DS_OUTPUT Input) : SV_TARGET {
    return float4(1,1); }

我的着色器初始化。代码：

D3DCompileFromFile(L"shader.hlsl",NULL,"VShader","vs_5_0",&VS,&ERR);
D3DCompileFromFile(L"shader.hlsl","PShader","ps_5_0",&PS,&ERR); 
D3DCompileFromFile(L"shader.hlsl","HShader","hs_5_0",&HS,"DShader","ds_5_0",&DS,&ERR);

dev->CreateVertexShader(VS->GetBufferPointer(),VS->GetBufferSize(),&pVS);
dev->CreatePixelShader(PS->GetBufferPointer(),PS->GetBufferSize(),&pPS);
dev->CreateHullShader(HS->GetBufferPointer(),HS->GetBufferSize(),&pHS);
dev->CreateDomainShader(DS->GetBufferPointer(),DS->GetBufferSize(),&pDS);

devcon->VSSetShader(pVS,0);
devcon->HSSetShader(pHS,0);
devcon->DSSetShader(pDS,0);
devcon->PSSetShader(pPS,0);

输入描述符：

D3D11_INPUT_ELEMENT_DESC ied[] =
{
    {"POSITION",DXGI_FORMAT_R32G32B32_FLOAT,D3D11_INPUT_PER_VERTEX_DATA,0},{"COLOR",DXGI_FORMAT_R32G32B32A32_FLOAT,12,};

dev->CreateInputLayout(ied,2,VS->GetBufferPointer(),&pLayout);
devcon->IASetInputLayout(pLayout);

光栅化器：

D3D11_RASTERIZER_DESC RasterDesc = {};
RasterDesc.FillMode = D3D11_FILL_SOLID;
RasterDesc.CullMode = D3D11_CULL_NONE;
RasterDesc.DepthClipEnable = TRUE;
ID3D11RasterizerState* WireFrame=NULL;

dev->CreateRasterizerState(&RasterDesc,&WireFrame);
devcon->RSSetState(WireFrame);

输入顶点：

OurVertices = (VERTEX*)malloc(PointCount * sizeof(VERTEX));
for (int i = 0; i < PointCount; i++)
{
    OurVertices[i] = { RandOm() * i,RandOm() * i,RandOm(),{abs(RandOm()),abs(RandOm()),1.0f} };
}

CBuffer：

ID3D11Buffer* g_pConstantBuffer11 = NULL;
cbuff.world = XMMatrixOrthographicOffCenterLH(SceneY - (ViewPortWidth / 2) * SceneZoom,SceneY + (ViewPortWidth / 2) * SceneZoom,SceneX - (ViewPortHeight / 2) * SceneZoom,SceneX + (ViewPortHeight / 2) * SceneZoom,-10000.0f,10000.0f);

D3D11_BUFFER_DESC cbDesc;
cbDesc.ByteWidth = sizeof(CBUFFER);
cbDesc.Usage = D3D11_USAGE_DYNAMIC;
cbDesc.BindFlags = D3D11_BIND_CONSTANT_BUFFER;
cbDesc.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE;
cbDesc.MiscFlags = 0;
cbDesc.StructureByteStride = 0;
   
D3D11_SUBRESOURCE_DATA InitData;
InitData.pSysMem = &cbuff;
InitData.SysMemPitch = 0;
InitData.SysMemSlicePitch = 0;

dev->CreateBuffer(&cbDesc,&InitData,&g_pConstantBuffer11);

devcon->VSSetConstantBuffers(0,1,&g_pConstantBuffer11);

渲染时：

devcon->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_3_CONTROL_POINT_PATCHLIST); 

所有可能的异常都在此代码中处理。只是为了干净的代码，它们被删除。并且在 Init 和 Render 阶段没有警告或异常。 我什至无法调试它，因为没有任何东西被吸引到输出中。另外，有什么方法可以查看着色器的输出值吗？
