[DX11] Render a simple ID3D11Texture2D

[DX11] Render a simple ID3D11Texture2D
I am trying set up a deferred shading class.
But i am not able to bin the Texture2D to the shader.
First i create a Renter Target and then i render the Color.
Second i set the Backbuffer as RT and i try to render the ColorTexture to the screen.
Here is the code:
void Mesh::InitShaderResourceView()
D3D11_TEXTURE2D_DESC texD
memset(&texDesc,0,sizeof(D3D11_TEXTURE2D_DESC));
texDesc.Width
texDesc.Height
texDesc.Format
= DXGI_FORMAT_R8G8B8A8_UNORM;
texDesc.MipLevels = 1;
texDesc.ArraySize = 1;
texDesc.SampleDesc.Count = 1;
texDesc.Usage = D3D11_USAGE_IMMUTABLE;
texDesc.BindFlags
= D3D11_BIND_SHADER_RESOURCE;
D3D11_RENDER_TARGET_VIEW_DESC renderTargetViewD
renderTargetViewDesc.Format = texDesc.F
renderTargetViewDesc.ViewDimension = D3D11_RTV_DIMENSION_TEXTURE2D;
renderTargetViewDesc.Texture2D.MipSlice = 0;
RAWGraphic.GetDevice()-&CreateTexture2D( &texDesc, 0, &NormalTex ) ;
RAWLog.FunctionResult(&GetBuffer&,RAWGraphic.GetSwapChain()-&GetBuffer( 0, __uuidof( ID3D11Texture2D ), ( LPVOID* )&NormalTex ));
RAWLog.FunctionResult(&CreateRenderTargetView&,RAWGraphic-&CreateRenderTargetView( NormalTex, &renderTargetViewDesc, &pRenderTargetView));
D3D11_SHADER_RESOURCE_VIEW_DESC srv_
memset(&srv_desc,0,sizeof(D3D11_SHADER_RESOURCE_VIEW_DESC));
srv_desc.Format=texDesc.F
srv_desc.ViewDimension=D3D11_SRV_DIMENSION_TEXTURE2D;
srv_desc.Texture2D.MipLevels=texDesc.MipL
RAWGraphic.GetDevice()-&CreateShaderResourceView(NormalTex,&srv_desc,&SRV);
D3D11_SAMPLER_DESC samplerD
samplerDesc.Filter = D3D11_FILTER_MIN_MAG_MIP_LINEAR;
samplerDesc.AddressU = D3D11_TEXTURE_ADDRESS_WRAP;
samplerDesc.AddressV = D3D11_TEXTURE_ADDRESS_WRAP;
samplerDesc.AddressW = D3D11_TEXTURE_ADDRESS_WRAP;
samplerDesc.MipLODBias = 0.0f;
samplerDesc.MaxAnisotropy = 1;
parisonFunc = D3D11_COMPARISON_ALWAYS;
samplerDesc.BorderColor[0] = 0;
samplerDesc.BorderColor[1] = 0;
samplerDesc.BorderColor[2] = 0;
samplerDesc.BorderColor[3] = 0;
samplerDesc.MinLOD = 0;
samplerDesc.MaxLOD = D3D11_FLOAT32_MAX;
// Create the texture sampler state.
RAWGraphic.GetDevice()-&CreateSamplerState(&samplerDesc, &sampler);
RAWGraphic.GetContext()-&OMSetRenderTargets( 1, &pRenderTargetView, NULL );
float col[4] = {0.0f, 1.0f, 0.0f, 1.0f};
RAWGraphic.GetContext()-&ClearRenderTargetView(pRenderTargetView, col);
RAWGraphic.GetContext()-&VSSetShader( m_sColor.VS, NULL, 0);
RAWGraphic.GetContext()-&PSSetShader( m_sColor.PS, NULL, 0);
RAWGraphic.GetContext()-&VSSetConstantBuffers( 0, 1, &MatrixBuffer);
RAWGraphic.GetContext()-&PSSetShaderResources( 0, 1,&TextureSRV);
RAWGraphic.GetContext()-&PSSetSamplers( 0, 1, &pSamplerLinear);
RenderBuffer();
void Mesh::Draw()
DeferredShading();
float col[4] = {1.0f, 1.0f, 1.0f, 1.0f};
RAWGraphic.GetContext()-&ClearRenderTargetView(RAWGraphic.GetRTV(), col);
RAWGraphic.GetContext()-&VSSetShader( m_sTexture.VS, NULL, 0);
RAWGraphic.GetContext()-&PSSetShader( m_sTexture.PS, NULL, 0);
RAWGraphic.GetContext()-&VSSetConstantBuffers( 0, 1, &MatrixBuffer);
RAWGraphic.GetContext()-&PSSetShaderResources( 0, 1,&SRV);
RAWGraphic.GetContext()-&PSSetSamplers( 0, 1, &sampler);
RenderBuffer();
Re: [DX11] Render a simple ID3D11Texture2D
I am new, is there no way to format the text.
So it looks horrible :S
