directx

问题 I am using Visual Studio 2017 and I'm required to use DirectX9.0 for a school project. I have a solution with 3 projects. One is a static library (.lib), one is an application (.exe) and one is a unit test project: KB01_Game.exe imports KB01_Engine.lib like so: KB01_Game properties KB01_Engine.lib contains the d3dx9 references like so (I have also tried reversing the order of these DXSDK references, with no success): KB01_Engine properties The files in KB01_Engine include the directx 9

问题 I'm trying to call this native Windows method using JNA: HRESULT WINAPI DirectSoundCreate(LPGUID lpGuid, LPDIRECTSOUND* ppDS, LPUNKNOWN pUnkOuter ); But I'm really struggling with understanding what I should use as parameters on the Java side of things. With JNA you're supposed to create Java classes matching the native C structs, and I have done so succesfully with other parts of the WinAPI. From what I've (I think) understood so far the LPDIRECTSOUND is a typedef to a "Long pointer to a

问题 In our C# WPF we use a 3rd party (unmanaged) library that display a map. We use the System.Windows.Interop.D3DImage class. The 3rd party library uses Direct3D for the the IntPtr32 surface location property. When i open a remote desktop from another computer and trying to view the WPF Client, we see the map. Once the WPF UI Client is up, and I minimize the RDP session or close the RDP i will get exception: Direct3D device is lost From my experience with video streaming applications, When a

问题 I've been trying various things for a year. I am a at beginner's level in python. Did the first two questions in Project Euler. I have tried a few methods to try and simulate keys in games I play. I can easily do this with autohotkey and macro keyboards/mouse. However, I would like to accomplish this through Python or C. My guess is that win32 api is ignored in video games and I need to simulate key presses through Direct X. Thank you in advance. Here is my latest attempt... it failed. I do

问题 I am quite desperate to achieve desired alpha blending results in DirectX. I am try to draw texture, and on it a color triangle strip. Despite all my attempts it seems that color of the strip is affected by the color of the texture drawn before. Even if I set D3DRS_ALPHABLENDENABLE to FALSE, I still see the color affected. Here is how the image suppose to looks like (Rendered with openGL) And here is what I get with directX rendering: As you can see, the second image purple strip has yellow

问题 I need to create a transparent bitmap using Direct2D and draw, by using my device context, on it. ID2D1DeviceContext1* d2dContext = ...
