Hello, I'm having some trouble getting a simple triangle to render. I've done this before (yesterday actually with a cube), but I must have lost it or something. Looking in PIX it looks like the vertices all get set to zero after the vertex shader stage. I don't understand why, but I'm a noob so I don't understand this stuff. I was hoping somebody might take a look at the code and see if they can't help me out, I'd really appreciate it. Thanks.

I've programmed a simple little app that renders a triangle to the screen. Whenever I maximize the screen or drag the resize bars the triangle squishes and stretches along with the window. I wrote a function that uses IDXGISwapChain::ResizeBuffers() to resize the swap chain's buffers in response to a WM_SIZE message but it doesn't seem to fix the distortion. Am I misunderstanding the purpose of IDXGISwapChain::ResizeBuffers()?

Here's my OnResize() function. I'm either doing something wrong, or ResizeBuffers doesn't do what I though it did. Sorry if this is a dumb question

[source lang="cpp"]HRESULT OnResize(LPARAM lParam){ g_pImmediateContext->OMSetRenderTargets(0, 0, 0); // Release any extraneous instances of swap chain's buffers. The render // target view typically holds references to swap chain's buffers. g_pRenderTargetView->Release(); UINT width = LOWORD(lParam); UINT height = HIWORD(lParam); // Resize swap chain's buffers. HRESULT hr = g_pSwapChain->ResizeBuffers(1, width, height, DXGI_FORMAT_R8G8B8A8_UNORM, 0);   if(FAILED(hr)) { MessageBox(NULL, "[ERROR] Failed to resize buffers.\nOnResize() in rederer.cpp", "ERROR", MB_ICONERROR | MB_OK); return hr; } // Get buffer and create render target view. ID3D11Texture2D* pBackBuffer = nullptr; hr = g_pSwapChain->GetBuffer(0, __uuidof(ID3D11Texture2D), (void**)&pBackBuffer); if(FAILED(hr)) { MessageBox(NULL, "[ERROR] Failed to get back buffer.\nOnResize() in renderer.cpp", "ERROR", MB_ICONERROR | MB_OK); return hr; } hr = g_pD3DDevice->CreateRenderTargetView(pBackBuffer, NULL, &g_pRenderTargetView); pBackBuffer->Release(); if(FAILED(hr)) { MessageBox(NULL, "[ERROR] Failed to create render target view." "\nOnResize() in renderer.cpp", "ERROR", MB_ICONERROR | MB_OK); return hr; } g_pImmediateContext->OMSetRenderTargets(1, &g_pRenderTargetView, NULL); // Set up viewport. D3D11_VIEWPORT vp; vp.Width = (float)width; vp.Height = (float)height; vp.MinDepth = 0.0f; vp.MaxDepth = 1.0f; vp.TopLeftX = 0; vp.TopLeftY = 0; g_pImmediateContext->RSSetViewports(1, &vp); return S_OK;}[/source]


And here's the little snippet inside of WndProc() where I call it.

[source lang="cpp"]case WM_SIZE:  if(g_pSwapChain)  {   OnResize(lParam);  }  return 0;[/source]


Thanks for the help.

Does anyone know how I can get rid of these macro redefinition warnings in Visual Studio 2012 Express?

Thanks .

What exactly should I set for BufferCount in the DXGI_SWAP_CHAIN_DESC structure if I want double buffering? The SDK documentation sets this value to 1. But wouldn't that only create one buffer? Shouldn't I set this field to 2 if I want a front buffer and a back buffer? The docs say "you typically include the front buffer in this value". That has me a little confused...

Hello to you all. I purchased the book "Introduction to Algorithms" because I'd like to get a better understanding of the sorts of algorithms and data structures that are used in game programming. The first thing that I noticed about the book is that it is HUGE. There's no way I could just sit down and read this thing from cover to cover, and even if I did I would hardly be able to retain all of that information.. I plan on going through all of the sorting algorithms since the book mentions that they are used by many of the other algorithms, and I am already familiar with linked-lists. What other algorithms and data structures are common in game programming?
