Copy depth buffer with non-lockable format (D24S8) to system memory with Direct3D9, Win 8.1

问题 EDIT: As ozeanix points out in the comments it is not possible to copy a D24S8 surface to system memory. Unfortunately you also cannot bind the surface (or rather its containing texture) to a pixel shader. I ended up going the reimplementation way, intercepting all D3D9 calls. If the graphics card supports it - all cards with DX10+ should do - it is sometimes possible to exchange the D24S8 format with FOURCC INTZ, which has the same memory layout, but can be bound to a pixel shader's texture

How do I render a fullscreen frame with a different resolution than my display?

问题 I am in the process of teaching myself DirectX development while going through all the tutorials on http://directxtutorial.com/. I have run into a problem that I believe is related to me having multiple monitors. My display is 1920 x 1080. When my code runs in its current state my primary monitor becomes black with the cursor in the middle. When I set my SCREEN defines at the top of my code to 1920 x 1080 my program runs fine and displays my sprite with the navy background. When I leave the

What is the Xbox360's D3DRS_VIEWPORTENABLE equivalent on WinXP D3D9?

问题 I am maintaining a multiplatform codebase for Xbox360 and WinXP. I am seeing an issue on the XP side that appears to be related to D3DRS_VIEWPORTENABLE on the Xbox360 version not having an equivalent on WinXP D3D9. This article had an interesting idea, but the only way to construct an identity matrix is to supply negative numbers to D3DVIEWPORT9::X and D3DVIEWPORT9::Height, but they are unsigned numbers. (I tried to put in negative numbers anyway, but nothing interesting happened.) So, how

How to enable VSYNC in D3D windowed app?

问题 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: DISCARD Each time OnPaint is called, I render the image to the backbuffer and present it to front. As far as I know (and so does MSDN say), once I set D3DPRESENT_INTERVAL_ONE , vsync will work. But in this case, the image is teared when dragging horizontally. (It seems there's a line across the image,

how to convert XMMATRIX to D3DMATRIX in DirectX 9?

问题 I learn DirectX (DirectX 9) from www.directxtutorial.com and using visual studio 2012 in windows 8. d3dx9 (d3dx) replace by other header like DirectXMath, therefore I replaced all that is needed, but there is a problem - convert XMMATRIX to D3DMATRIX. The problem code (The problem written - / problem! /): void render_frame(void) { // clear the window to a deep blue d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 0, 0), 1.0f, 0); d3ddev->BeginScene(); // begins the 3D scene // select
