基本上我制作了一个带有动画的 .x 文件模型类，每个模型类都有一个指向效果文件类的指针，所以我制作了一堆不同的模型，我让它们都使用一个单一的效果，例如发光，所以在DrawSubset()每个模型的渲染功能中都是Begin()为了End()效果。问题是我 90% 的 .fx 文件（我尝试在 FX 作曲家和 Rendermonkey 中制作，我尝试加载样本，甚至是简单的样本）它们没有加载并且它说效果是空的，如果有东西设法加载，它会使所有几何图形变灰或切掉它的一部分。这基本上是我的代码（哦，d3d设备指针设置正确，别担心，问题不是那里）：

}

在模型类中它呈现在这里：

this->Effect->Set();

    this->Effect->cPasses = 0;

    if( SUCCEEDED( Effect->anEffect->Begin(&this->Effect->cPasses, 0) ) ){

        for (DWORD i = 0; i < this->Effect->cPasses; i++)
     {
      Effect->anEffect->BeginPass(i);

      pDrawMesh->DrawSubset(iMaterial);

      Effect->anEffect->EndPass();
     }
      Effect->anEffect->End();
     }

我根据我在 .fx 文件中看到的内容在 cPasses 上尝试了不同的值，但这并没有真正的区别。没有 .fx 文件，我的 .x 文件可以完美地呈现纹理和动画……我从没想过 .fx 文件太难了，这就像 DirectX 迄今为止最令人困惑的部分！

好的，看看“EdgeFuzz.fx” *请发布文件给大家看看着色器使用以下顶点输入。

/* data from application vertex buffer */
  struct appdata {
     float3 Position    : POSITION;
     float4 UV      : TEXCOORD0;
     float4 Normal  : NORMAL;
     float4 Tangent : TANGENT0;
     float4 Binormal    : BINORMAL0;
};

我在您的代码中没有看到与上述语义相匹配的顶点缓冲区？即您将需要创建一个顶点缓冲区，匹配信息顶点（语义：POSITION），纹理坐标：语义：TEXCOORD0，法线（用于照明，语义：NORMAL），（凹凸贴图的切线和副法线）

然后必须用上述结构中的网格几何体填充顶点缓冲区（您需要创建一个 c++ 结构以匹配上述 hlsl 结构）

还是您可能从帖子中排除了更多代码？我希望这对您有所帮助，因为当您调用技术（Main）（在“EdgeFuzz.fx”着色器中定义）时，该顶点着色器将获取该几何信息，并做这件事
