  1. Hi AlzPatz. I received your code, however I currently have no win8 dev environment therefore no chance to compile your code. The code and the shaders seem fine, but the devil is in the details as usual. To diagnose my problem I switched the cull mode to D3D11_CULL_NONE so the rasterizer would render everything that should be on screen. in native c++ it would look somethin like this: [source] D3D11_RASTERIZER_DESC rd; ZeroMemory(&rd, sizeof(rd)); rd.CullMode = D3D11_CULL_NONE; rd.FrontCounterClockwise = false; rd.FillMode = D3D11_FILL_SOLID; device->CreateRasterizerState(&rd, &rasterizerState); immediateContext->RSSetState(rasterizerState); [/source] Also try to disable the depthstencilbuffer as you don't need it anyway when you draw screen coordinates directly, by not setting in the OMSetRenderTargets call: [source] //Set the Render Context d3dContext->OMSetRenderTargets(1, renderTargetView.GetAddressOf(), nullptr) [/source] You should also have a look at the DX11 MSDN tutorial (especially No 2), if you have not already. [url="http://code.msdn.microsoft.com/Direct3D-Tutorial-Win32-829979ef?SRC=VSIDE"]http://code.msdn.mic...979ef?SRC=VSIDE[/url] I hoped I could be more helpful. Let me know if that brought you forward. C.
  2. I solved the issue for me, but you seem to use untransformed screen coordinates. The root cause with my code were the Projection and View matrices. While I stored the world matrix correctly: [Code]sChangesEveryFrame.mWorld = XMMatrixTranspose(XMLoadFloat4x4(&worldMatrix));[/Code] I did not do it with the other two: [CODE]sNeverChanges.mView = XMLoadFloat4x4(&ViewMatrix);[/CODE] and [CODE]sChangesOnResize.mProjection = XMLoadFloat4x4(&ProjectionMatrix);[/CODE] The shader has to use a transposed version of the matrices. AlzPatz - I will get in touch with you via PM.
  3. The problem you are describing sound like the exact same problem when I try to render a cube. Inspecting the problem with the Graphics Diagnosis Tool tells me that the Pixel Shader has not participate in the graphics pipeline process, in my case, without any obvious reason. I have double checked it, but it was loaded properly and set correctly in the device context. This leaves me clueless. Perhaps the additional diag info helps in your case as well, AlzPatz. (see attachment) And this is the corresponding source code Cube.cpp: [Code] #include "Cube.h" #include "GlobalDefines.h" #include "Direct3dUtils.h" struct SChangesEveryFrame{ XMMATRIX mWorld; }; Cube::Cube(void) :isInitialized(false), vertexBuffer(NULL), indexBuffer(NULL), cbChangesEveryFrame(NULL), vertexShaderFile(L"SimpleVertexShader"), pixelShaderFile(L"SimplePixelShader"), vertexShader(NULL), pixelShader(NULL), inputLayout(NULL) { } Cube::~Cube(void) { SAFE_RELEASE(inputLayout);
