纹理将不适用于我的3D立方体directX

我想将纹理应用到我的3D立方体，但它没有正确显示。我相信这可能是一些工作的原因，因为立方体全是棕色，与纹理几乎一样的肤色。我最初并没有将立方体变成棕色。这是我对我所做的添加纹理纹理将不适用于我的3D立方体directX

的步骤我先宣布2个新的变量下

ID3D10EffectShaderResourceVariable* pTextureSR; 
ID3D10ShaderResourceView* textureSRV;

我还添加了一个变量，一个struct到我的着色器.FX文件

Texture2D tex2D; 

SamplerState linearSampler 
{ 
    Filter = MIN_MAG_MIP_LINEAR; 
    AddressU = Wrap; 
    AddressV = Wrap; 
};

然后我从.cpp文件中的本地硬盘驱动器中抓取图像。我相信这是成功的，我检查了所有的错误，一切都有一个内存地址。另外我之前从事资源的工作并没有遇到任何问题。

D3DX10CreateShaderResourceViewFromFile(mpD3DDevice,L"crate.jpg",NULL,NULL,&textureSRV,NULL);

我一把抓起我的FX文件tex2d varible并放入我的资源varible

pTextureSR = modelObject.pEffect->GetVariableByName("tex2D")->AsShaderResource();

，并添加了资源的varible

pTextureSR->SetResource(textureSRV);

我还添加了额外的属性我的顶点布局

D3D10_INPUT_ELEMENT_DESC layout[] = { 
    {"POSITION",0,DXGI_FORMAT_R32G32B32_FLOAT, 0 , 0, D3D10_INPUT_PER_VERTEX_DATA, 0}, 
    {"COLOR",0,DXGI_FORMAT_R32G32B32A32_FLOAT, 0 , 12, D3D10_INPUT_PER_VERTEX_DATA, 0}, 
    {"NORMAL",0,DXGI_FORMAT_R32G32B32A32_FLOAT, 0 , 24, D3D10_INPUT_PER_VERTEX_DATA, 0}, 
    {"TEXCOORD",0, DXGI_FORMAT_R32G32_FLOAT, 0 , 36, D3D10_INPUT_PER_VERTEX_DATA, 0} 
};

以及我的结构

struct VertexPos 
{ 
    D3DXVECTOR3 pos; 
    D3DXVECTOR4 color; 
    D3DXVECTOR3 normal; 
    D3DXVECTOR2 texCoord; 
};

然后，我创建了一个新的像素着色器，增加了纹理。下面是它的全部

matrix Projection; 
matrix WorldMatrix; 
Texture2D tex2D; 

float3 lightSource; 
float4 lightColor = {0.5, 0.5, 0.5, 0.5}; 

// PS_INPUT - input variables to the pixel shader 
// This struct is created and fill in by the 
// vertex shader 
struct PS_INPUT 
{ 
    float4 Pos : SV_POSITION; 
    float4 Color : COLOR0; 
    float4 Normal : NORMAL; 
    float2 Tex : TEXCOORD; 
}; 

SamplerState linearSampler 
{ 
    Filter = MIN_MAG_MIP_LINEAR; 
    AddressU = Wrap; 
    AddressV = Wrap; 
}; 


//////////////////////////////////////////////// 
// Vertex Shader - Main Function 
/////////////////////////////////////////////// 
PS_INPUT VS(float4 Pos : POSITION, float4 Color : COLOR, float4 Normal : NORMAL, float2 Tex : TEXCOORD) 
{ 
    PS_INPUT psInput; 

    // Pass through both the position and the color 
    psInput.Pos = mul(Pos, Projection); 
    psInput.Normal = Normal; 
    psInput.Tex = Tex; 

    return psInput; 
} 

/////////////////////////////////////////////// 
// Pixel Shader 
/////////////////////////////////////////////// 
float4 PS(PS_INPUT psInput) : SV_Target 
{ 
    float4 finalColor = 0; 
    finalColor = saturate(dot(lightSource, psInput.Normal) * lightColor); 

    return finalColor; 
} 

float4 textured(PS_INPUT psInput) : SV_Target 
{ 
    return tex2D.Sample(linearSampler, psInput.Tex); 
} 



// Define the technique 
technique10 Render 
{ 
    pass P0 
    { 
     SetVertexShader(CompileShader(vs_4_0, VS())); 
     SetGeometryShader(NULL); 
     SetPixelShader(CompileShader(ps_4_0, textured())); 
    } 
}

好了，我在下面的代码

HRESULT *pHResult = NULL; 

D3DX10CreateShaderResourceViewFromFile(mpD3DDevice,L"crate.jpg",NULL,NULL,&textureSRV,pHResult);

我添加了一个HRESULT检查结果，它什么都没有返回。 pHResult 0x00000的地址无法评估表达式。不知道是否因为它没有正确加载crate.jpg或什么。该位置是正确的。我的crate.jpg与我的effect.fx文件位于同一位置。我以同样的方式加载了我的效果文件。 “effect.fx”

如果有人可以看看我的顶点，并确保我的UV坐标是正确的。那太好了。我对此有点怀疑。

好的，没关系，我在MSDN中读到，pHResult值通常返回NULL。所以我添加它像这样... pHResult = D3DX10CreateShaderResourceViewFromFile（mpD3DDevice，L“crate.bmp”，NULL，NULL，＆textureSRV，NULL）; 它作为S_OK返回。我对这个问题无能为力。 – numerical25 2010-05-30 02:16:16

这是一个相当冗长的问题......好吧......更可能是一条废弃的线路上结束的思路。下次减价以获得一些利益。 – Jamie 2010-05-30 03:03:23

我想通了。在我的顶点布局描述中，我的偏移是关闭的。我将颜色增加了12，因为它应该是16，因为rgba。无论如何，我纠正它，现在纹理出现，但不正确。我会针对该问题发布另一个消息。
