I am developing a code that will be used for motion control and I am having a issue with the pow function. I am using VS2010 as IDE. Here is my issue: I have: double p = 100.0000; double d = 1000.0000; t1 = pow((p/(8.0000*d),1.00/4.000); When evaluating this last function, I don't get the better approximation as result. I am getting a 7 decimal digits correct, and the consequent digits are all trash. I am guessing that pow function only casts any input variable as float and proceds with calculation. Am I right? If so, is there any code I can get "inspired" with to reimplement pow for a better

I am creating a multi-monitor full screen DXGI/D3D application. I am enumerating through the available outputs and adapters in preparation of creating their swap chains. When creating my swap chain using DXGI's IDXGIFactory::CreateSwapChain method, I need to provide a swap chain description which includes a buffer description of type DXGI_MODE_DESC that details the width, height, refresh rate, etc. How can I find out what the output is currently set to (or how can I find out what the display mode of the output currently is)? I don't want to change the user's resolution or refresh rate when I

I have a wxWidgets application that has a number of child opengl windows. I'm using my own GL canvas class, not the wx one. The windows share their OpenGL context. I don't think the fact it is wxwidgets is really relevant here. The opengl windows are children of a windows that are siblings of one another, contained within a tab control. Kind of an MDI style interface, but it is not an MDI window.. Each one can be individually resized. All works lovely unless Aero is enabled and the DWM is active. Resizing any window (not even the opengl ones) causes all of the opengl windows to flicker

How do I create a cube map in D3D11 from 6 images? All the examples I've found use only one .dds. Specifically, how do I upload individual faces of the cube texture? It works like this: D3D11_TEXTURE2D_DESC texDesc; texDesc.Width = description.width; texDesc.Height = description.height; texDesc.MipLevels = 1; texDesc.ArraySize = 6; texDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM; texDesc.CPUAccessFlags = 0; texDesc.SampleDesc.Count = 1; texDesc.SampleDesc.Quality = 0; texDesc.Usage = D3D11_USAGE_DEFAULT; texDesc.BindFlags = D3D11_BIND_SHADER_RESOURCE; texDesc.CPUAccessFlags = 0; texDesc.MiscFlags

I've tried for many months to learn how IDirect3DVertexBuffer9 and IDirect3DIndexBuffer9 work. I've read multiple books, e-books and forums and I still can't get the hang of how they work. Can somebody help me understand how they work and how they link together? PS: I've tried searching through the related questions but nothing interested me. Thanks. IndexBuffers are used for memory & speed optimizations. A indexBuffer is a list of indices that index the vertices in the vertexBuffer. So say I'm going to render a Flat Quad on the screen with 2 triangles. Each triangle takes up 3 vertices, so to
