DX11 D3D10CompileShader equivelent in D3D11

Recommended Posts

Hey guys,

I'm working on my wrappers for the various flavors of D3D. I have 10 and 10.1 working fine, and am about halfway through D3D11. But I've hit a snag with the shaders.

In D3D10, there is the function D3D10CompileShader. This function appears to have been removed from DX11 (i.e. there is no D3D11CompileShader function). How, then, would I compile shaders?

Oh, and don't say "D3DXCompileFrom*". Not interested. There is no D3DX in my code, it's not a dependency I need or want. I'm looking for core functions/interfaces only.

Thanks gang.

That's an HLSL function. Sorry, I guess I should have been more specific. I want to compile the shader in the C++ code, not in HLSL. e.g. this is my D3D 10.1 wrapper function. I want somthing similar for my D3D 11 wrapper.


HRESULT DX10_1Wrapper::CompileShader(String *Source, String *MainFunction, String *ShaderProfile, unsigned int Flags, ID3D10Blob **Shader, ID3D10Blob **Errors)
{
return D3D10CompileShader(Source->c_strA(), Source->Size(), nullptr, nullptr, nullptr, MainFunction->c_strA(), ShaderProfile->c_strA(), Flags, Shader, Errors);
}

Really? Hmmmmmm.

Okay, well, perhaps you could me a bit more of a clue. Because this:


HRESULT DX11Wrapper::CompileShader(String *Source, String *MainFunction, String *ShaderProfile, unsigned int Flags, ID3DBlob **Shader, ID3DBlob **Errors)
{
return D3DCompile(Source->c_strA(), Source->Size(), nullptr, nullptr, nullptr, MainFunction->c_strA(), ShaderProfile->c_strA(), Flags, Shader, Errors);
}


gives me

1>e:\engine\graphicsapiwrapper.cpp(1024): error C3861: 'D3DCompile': identifier not found

I've hunted through a bunch of the interface docs to see if they associated it with something (like the device, device context, all the shader interfaces, and so on), but I don't see it. And the search is just giving the same link to the HLSL page that Erik linked to.

Sorry for my being dense. I'm just not getting how to call that HLSL function in a C++ environment.

There's no HLSL function. It's declared in D3DCompiler.h, and you have to link to d3dcompiler.lib. It's implemented in a DLL (D3dcompiler_xx.dll) that gets installed with the redistributable, so if you're looking to avoid that you're out of luck.

      I am trying to add normal map to my project I have an example of a cube: 
      I have normal in my shader I think. Then I set shader resource view for texture (NOT BUMP)
                  device.ImmediateContext.PixelShader.SetShaderResource(0, textureView);             device.ImmediateContext.Draw(VerticesCount,0); What should I do to set my normal map or how it is done in dx11 generally example c++?

      Imagine that we have a vertex structure that looks like this:
      struct Vertex { XMFLOAT3 position; XMFLOAT4 color; }; The vertex shader looks like this:
      cbuffer MatrixBuffer { matrix world; matrix view; matrix projection; }; struct VertexInput { float4 position : POSITION; float4 color : COLOR; }; struct PixelInput { float4 position : SV_POSITION; float4 color : COLOR; }; PixelInput main(VertexInput input) { PixelInput output; input.position.w = 1.0f; output.position = mul(input.position, world); output.position = mul(output.position, view); output.position = mul(output.position, projection); output.color = input.color; return output; } And the pixel shader looks like this:
      struct PixelInput { float4 position : SV_POSITION; float4 color : COLOR; }; float4 main(PixelInput input) : SV_TARGET { return input.color; } Now let's create a quad consisting of 2 triangles and the vertices A, B, C and D:
      // Vertex A. vertices[0].position = XMFLOAT3(-1.0f, 1.0f, 0.0f); vertices[0].color = XMFLOAT4( 0.5f, 0.5f, 0.5f, 1.0f); // Vertex B. vertices[1].position = XMFLOAT3( 1.0f, 1.0f, 0.0f); vertices[1].color = XMFLOAT4( 0.5f, 0.5f, 0.5f, 1.0f); // Vertex C. vertices[2].position = XMFLOAT3(-1.0f, -1.0f, 0.0f); vertices[2].color = XMFLOAT4( 0.5f, 0.5f, 0.5f, 1.0f); // Vertex D. vertices[3].position = XMFLOAT3( 1.0f, -1.0f, 0.0f); vertices[3].color = XMFLOAT4( 0.5f, 0.5f, 0.5f, 1.0f); // 1st triangle. indices[0] = 0; // Vertex A. indices[1] = 3; // Vertex D. indices[2] = 2; // Vertex C. // 2nd triangle. indices[3] = 0; // Vertex A. indices[4] = 1; // Vertex B. indices[5] = 3; // Vertex D. This will result in a grey quad as shown in the image below. I've outlined the edges in red color to better illustrate the triangles:

      Now imagine that we’d want our quad to have a different color in vertex A:
      // Vertex A. vertices[0].position = XMFLOAT3(-1.0f, 1.0f, 0.0f); vertices[0].color = XMFLOAT4( 0.0f, 0.0f, 0.0f, 1.0f);
      That works as expected since there’s now an interpolation between the black color in vertex A and the grey color in vertices B, C and D. Let’s revert the previus changes and instead change the color of vertex C:
      // Vertex C. vertices[2].position = XMFLOAT3(-1.0f, -1.0f, 0.0f); vertices[2].color = XMFLOAT4( 0.0f, 0.0f, 0.0f, 1.0f);
      As you can see, the interpolation is only done half of the way across the first triangle and not across the entire quad. This is because there's no edge between vertex C and vertex B.
      Which brings us to my question:
      I want the interpolation to go across the entire quad and not only across the triangle. So regardless of which vertex we decide to change the color of, the color interpolation should always go across the entire quad. Is there any efficient way of achieving this without adding more vertices and triangles?
      An illustration of what I'm trying to achieve is shown in the image below:

      This is just a very brief explanation of the problems background in case that would make it easier for you to understand the problems roots and maybe help you with finding a better solution to the problem.
      I'm trying to texture a terrain mesh in DirectX11. It's working, but I'm a bit unsatisfied with the result. When changing the terrain texture of a single vertex, the interpolation with the other vertices results in a hexagon shape instead of a squared shape:

      As the red arrows illustrate, I'd like the texture to be interpolated all the way into the corners of the quads.

      Hello, I'm close to releasing my first game to Steam however, my game keeps failing the review process because it keeps crashing. The problem is that the game doesn't crash on my computer, on my laptop, on our family computer, on fathers laptop and i also gave 3 beta keys to people i know and they said the game hasn't crashed.
      Steam reports that the game doesn't crash on startup but few frames after a level has been started.
      What could cause something like this? I have no way of debugging this as the game works fine on every computer i have.
       
      Game is written in C++, using DirectX 11 and DXUT framework.

      I'm trying to get, basically, screenshot (each 1 second, without saving) of Direct3D11 application. Code works fine on my PC(Intel CPU, Radeon GPU) but crashes after few iterations on 2 others (Intel CPU + Intel integrated GPU, Intel CPU + Nvidia GPU).
      void extractBitmap(void* texture) { if (texture) { ID3D11Texture2D* d3dtex = (ID3D11Texture2D*)texture; ID3D11Texture2D* pNewTexture = NULL; D3D11_TEXTURE2D_DESC desc; d3dtex->GetDesc(&desc); desc.BindFlags = 0; desc.CPUAccessFlags = D3D11_CPU_ACCESS_READ | D3D11_CPU_ACCESS_WRITE; desc.Usage = D3D11_USAGE_STAGING; desc.Format = DXGI_FORMAT_R8G8B8A8_UNORM_SRGB; HRESULT hRes = D3D11Device->CreateTexture2D(&desc, NULL, &pNewTexture); if (FAILED(hRes)) { printCon(std::string("CreateTexture2D FAILED:" + format_error(hRes)).c_str()); if (hRes == DXGI_ERROR_DEVICE_REMOVED) printCon(std::string("DXGI_ERROR_DEVICE_REMOVED -- " + format_error(D3D11Device->GetDeviceRemovedReason())).c_str()); } else { if (pNewTexture) { D3D11DeviceContext->CopyResource(pNewTexture, d3dtex); // Wokring with texture pNewTexture->Release(); } } } return; } D3D11SwapChain->GetBuffer(0, __uuidof(ID3D11Texture2D), reinterpret_cast< void** >(&pBackBuffer)); extractBitmap(pBackBuffer); pBackBuffer->Release(); Crash log:
      CreateTexture2D FAILED:887a0005 DXGI_ERROR_DEVICE_REMOVED -- 887a0020 Once I comment out 
      D3D11DeviceContext->CopyResource(pNewTexture, d3dtex); 
      code works fine on all 3 PC's.

      Hi i'm new to this forum and was wondering if there are any good places to start learning directX 11. I bought Frank D Luna's book but it's really outdated and the projects won't even compile. I was excited to start learning from this book because it gives detailed explanations on the functions being used as well as the mathematics. Are there any tutorials / courses /books that are up to date which goes over the 3D math and functions in a detailed manner? Or where does anyone here learn directX 11? I've followed some tutorials from this website http://www.directxtutorial.com/LessonList.aspx?listid=11 which did a nice job but it doesn't explain what's happening with the math so I feel like I'm not actually learning, and it only goes up until color blending. Rasteriks tutorials doesn't go over the functions much at all or the math involved either. I'd really appreciate it if anyone can point me in the right direction, I feel really lost. Thank you
