问题 I've installed .net 4.0 as well as XNA 4.0 . A while ago I used Microsoft.DirectX to play some music and now when I try to redo the work, I can't find the reference. Did the new changes on the platform modify or moved something in the references? 回答1: Visual Studio 2010: right click on project Menu select "Add reference..." select tab "Browse" select directory "C:\windows\assembly\ GAC\Microsoft.DirectX.AudioVideoPlayback The DLL to reference is in that folder. You will need to download and

问题 I have some code to draw some text: var textFormat = new SharpDX.DirectWrite.TextFormat(fontFactory, "Arial", SharpDX.DirectWrite.FontWeight.Bold, SharpDX.DirectWrite.FontStyle.Normal, SharpDX.DirectWrite.FontStretch.Condensed, 16.0f); renderTarget.DrawText("AC", textFormat, textRect, textBrush, DrawTextOptions.NoSnap); The text is drawn starting at the top-left of the target rectangle. Is there any way to right-justify the text? 回答1: The fourth entry for the google search "right justify text

问题 I am running Visual Studio 2012 on my Windows 7 machine. When I run the SimpleDirect2dApplication found here : http://technet.microsoft.com/en-us/subscriptions/dd940321%28v=vs.85%29.aspx hr = CoCreateInstance( CLSID_WICImagingFactory, NULL, CLSCTX_INPROC_SERVER, IID_PPV_ARGS(&m_pWICFactory) ); the CoCreateInstance fails with a "Class Not Registered" and the ptr to the factory is 0. Any help would be appreciated. 回答1: According to an answer in a Microsoft's forum a breaking change in the

问题 I am working on a extension to a game which only opens a HDC for addon developers to draw on. However, I have exhausted GDI+/Direct2D drawing possibilities that is fast enough for what I want to accomplish - image effects(Additive, Blend, Multiply Blend etc). I am well aware that Direct2D offers a effects toolkit however, that requires a platform update (for Windows 7) and that is not ideal at all. Hence I am left with only Direct3D. MSDN/Google Search offers lots of ways to do D2D -> D3D,

问题 If already have a DirectX texture in hand, what is the fast(low CPU utilization) way to get a RGB24 buffer in main RAM from it (skip the A)? Strictly the format is DXGI_FORMAT_B8G8R8A8_UNORM , does this mean ARGB? I'm using https://github.com/bmharper/WindowsDesktopDuplicationSample to capture Windows desktop and the result is to be converted into RGB24 lossless format in main RAM. The existing code copy GPU texture to CPU texture then use memcpy to copy each line of the RGBA32 data to main

问题 I am trying to debug a HLSL shader in VS2012 using NSight, but it can't start. When I click on "Start Graphics Debugging", it seems like it starts the app for a moment, and then closes it (output windows from NSight shows several "shader loaded"/"shader unloaded" lines). Windows Event log doesn't show anything (except "NVIDIA Network Service" failing to start, but if I understood well, this is something related to updates). On the other hand, if I start GPU Perfomannce analysis, then it runs

问题 I need to draw million cubes. Cubes has the same vertex array, but may have different scale/position/rotation. Important: they may change their position dynamically, after vertex buffer creation. Some of them should be connected by the line. So I also need to draw lines. Currently I deal with the instancing using constant buffer: VertexShader.hlsl struct VS_INPUT { float4 pos: POSITION; float4 colour: COLOUR; uint InstanceID: SV_InstanceID; } cbuffer ConstantBuffer : register(b0) { float4x4
