The problem: calling IDXGIOutput1::DuplicateOutput method returns DXGI_ERROR_UNSUPPORTED when you run an application using discrete graphics controller on a machine with switchable graphics. This ...

So I've recently picked up graphics programming and I wanted to compute a cubic Bézier curve. I found this excellent answer on quadratic Bézier but I don't know how to convert this to a cubic Bézie...

I want to do projects to make my resume more appealing to game companies. So I am going to start buying books. But I don't know rather to read DirectX 9 or 10 api books to start off with. DirectX10...

If you subdivide a cylinder into an 8-sided prism, calculating vertex normals based on their position ("smooth shading"), it looks pretty good. If you subdivide a cone into an 8-sided pyramid, cal...

I need to draw a list of shapes and I am using Direct2D. I get the list of shapes from a file. The list is sorted and the order of the elements inside the file represents the order these shapes wil...

I'm trying to use the following instructions to build some code that uses XAudio2 and runs on Windows 7: http://msdn.microsoft.com/en-us/library/windows/desktop/ee663275%28v=vs.85%29.aspx As sugg...

Background: I've developing in Visual Studio 2013 and targeting .Net 4.5, running on Windows 7. I've been trying to get DirectX to run in a WPF context and was referred to SharpDX, and to a sample ...

So the UWP Composition support has been out for a while I am looking for a way to do real-time blurring of elements (live blur as they move or load, not static snapshot). So far I have been looking...

My application is capturing desktop screen(screen sharing) and send to other device. Currently application captures screen with following method - using GDI (Bitblt) - using DirectX(getFrontB...

Pretty self explanatory. Microsoft had DirectShow for DirectX 9, but using DirectShow with DX11 is a COM nightmare beyond words. Is there a standard for video rendering I haven't heard of, or perha...

I have a simple question of which I was unable to find solid facts about GPUs behaviour in case of 3 vertexes having the same varying output from vertex shader. Does the GPU notice that case or do...

I'm in the process of learning C++ and DirectX, and I'm noticing a lot of duplication in trying to keep structs in my HLSL shaders and C++ code in sync. I'd like to share the structs, since both la...

I am doing desktop screen capture and wanted the output to be a video file. Currently I have codes getting from here to output png images. I modified the code a bit to change the output to JPEG fil...

If I understand correctly, scissor test is per fragment operation, but I was wondering if it's possible to put the test before fragment shader so that fragments outside scissor box don't need to be...

I've been looking all over the internet for this. I'd like to know if there is any Node.js packages/bindigs/libraries that allow you to make an application that draws on the screen without no...

So, Im using D3D in a windowed application. I inited D3D with the following parameters: windowed: true; backbufferformat: D3DFMT_X8R8G8B8; presentinterval: D3DPRESENT_INTERVAL_ONE; swapeffect: DI...

I'm trying to do vertical synced renders so that exactly one render is done per vertical sync, without skipping or repeating any frames. I would need this to work under Windows 7 and (in the future...

Is there any simple way that I can know some codes are executed in GPU rather than CPU?

I would like to capture the contents of my front or back buffer using DirectX 11 into an array of bytes which I can then use as a texture or as a source for creating a file. I have a swap chain set...

This is a bit of an edge case but I am developing a game which uses multiple monitors. For reasons outside the scope of this question, I am using a 'multi-device method' rather than swap chains. My...

I have the data of a spline curve Degree Knots Control points Fit points And I need to draw this curve by using Direct2D. At the moment I am using the ID2D1GeometrySink interface to draw geomet...

I want to develop universal windows apps using C++/DirectX/XAML. But it seems like there's no way to escape Microsoft's C++/CLI language. I've already browsed through the code that isnthere by defa...

I'm working on a C++ DirectX 2D game and I need keyboard and mouse input. Wikipedia says: Microsoft recommends that new applications make use of the Windows message loop for keyboard and mouse i...

I've looked at many posts here regarding PeekMessage and WM_MOUSEMOVE, but so far I have not found anything that relates to performance. Long story short; I'm doing PC game development and yesterd...

Is is possible to run a Java3D application on Nvidia 3D Vision hardware? I've got an existing Java3D application that can run in stereoscopic 3D. In the past, I've always run the application on Qu...
