I am trying to apply a texture onto my 3d cube but it is not showing up correctly. I believe that it might some what be working because the cube is all brown which is almost the same complexion as the texture. And I did not originally make the cube brown. These are the steps I've done to add the texture
I first declared 2 new varibles
ID3D10EffectShaderResourceVariable* pTextureSR;
ID3D10ShaderResourceView* textureSRV;
I also added a variable and a struct to my shader .fx file
Texture2D tex2D;
SamplerState linearSampler
{
Filter = MIN_MAG_MIP_LINEAR;
AddressU = Wrap;
AddressV = Wrap;
};
I then grabbed the image from my local hard drive from within the .cpp file. I believe this was successful, I checked all varibles for errors, everything has a memory address. Plus I pulled resources before and never had a problem.
D3DX10CreateShaderResourceViewFromFile(mpD3DDevice,L"crate.jpg",NULL,NULL,&textureSRV,NULL);
I grabbed the tex2d varible from my fx file and placed into my resource varible
pTextureSR = modelObject.pEffect->GetVariableByName("tex2D")->AsShaderResource();
And added the resource to the varible
pTextureSR->SetResource(textureSRV);
I also added the extra property to my vertex layout
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}
};
as well as my struct
struct VertexPos
{
D3DXVECTOR3 pos;
D3DXVECTOR4 color;
D3DXVECTOR3 normal;
D3DXVECTOR2 texCoord;
};
Then I created a new pixel shader that adds the texture to it. Below is the code in its entirety
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() ) );
}
}
Below is my CPU code. It maybe a little sloppy. But I am just adding code anywhere cause I am just experimenting and playing around. You should find most of the texture code at the bottom createObject

And here is my cube coordinates. I actually only added coordinates to one side. And that is the front side. To double check I flipped the cube in all directions just to make sure i didnt accidentally place the text on the incorrect side
