Nvidia 3d Video using DirectX11 and SlimDX in C#

问题 Good day, I am trying to display a real-time stereo video using nvidia 3DVision and two IP cameras. I am totally new to DirectX, but have tried to work through some tutorials and other questions on this and other sites. For now, I am displaying two static bitmaps for left and right eyes. These will be replaced by bitmaps from my cameras once I have got this part of my program working. This question NV_STEREO_IMAGE_SIGNATURE and DirectX 10/11 (nVidia 3D Vision) has helped me quite a bit, but I

SlimDX Device.Reset crashes with a “D3DERR_INVALIDCALL: Invalid call (-2005530516)” error

We recently upgraded from VS 2005 to VS 2008 (Windows XP). We use SlimDx in one of our projects. All was working ok after the upgrade, except my Recover function, which gets called on devicelost/device reset which crashes with D3DERR_INVALIDCALL: Invalid call (-2005530516) I use Ctrl - Alt - Del and then Escape to simulate device lost. void Recover() { try { if (res.Code == D3DERR_DEVICENOTRESET) { res = m_device.Reset(m_presentParams); //Crashes on this. if (res.IsSuccess) { m_deviceLost = false; } } } catch(Exception e) {} } Is this something to do with VS 2008 , as it used to work nicely

SlimDX/DirectX9/C# - How to access pixel-data in a Texture

This is my first question ever on StackOverflow, hurray! I can honestly say I use StackOverflow on daily basis for both my work and personal programming mysteries. 99,9% of the time I actually find the answer I need on here too, which is great! My current problem actually stumped me a little as I can't seem to find anything which actually works. I've already read several posts on GameDev.net and found other resources around the net but can't sort it out. I am in the process of porting a small 2D engine I wrote for XNA to SlimDX (just DirectX9 at the moment), which has been a good move as I

SlimDX: Joystick.Poll() succeeds on disconnected gamepad

问题 I've got a curious problem with SlimDX: we've seen this on Windows 7, and haven't yet tested other versions: I'm using a bundle of cheap USB gamepads (no serial number), and sometimes one physical gamepad ends up providing the input to more than one Joystick object. The scenario is: Plug in gamepad 1 to hub slot 1. Pad appears in DirectInput.GetDevices as GUID f17b2d30. Create Joystick object for pad. Plug in gamepad 2 to hub slot 2. Pad appears in DirectInput.GetDevices as GUID 5187d2d0.

How to rotate, scale, and translate a matrix all at once in C#?

问题 Okay, this is something that should be a simple matrix question, but my understanding of matrices is somewhat limited. Here's the scenario: I have a 1px by 1px sprite that I want to scale by some amount x and y (different amounts on each side), and then I want to rotate that sprite by some angle, and then I want to be able to precisely position the whole thing (from the top left or the center, makes no difference to me). So far my code is vaguely close, but it tends to be off by some random

NV_STEREO_IMAGE_SIGNATURE and DirectX 10/11 (nVidia 3D Vision)

I'm trying to use SlimDX and DirectX10 or 11 to control the stereoization process on the nVidia 3D Vision Kit. Thanks to this question I've been able to make it work in DirectX 9. However, due to some missing methods I've been unable to make it work under DirectX 10 or 11. The algorithm goes like this: Render left eye image Render right eye image Create a texture able to contain them both PLUS an extra row (so the texture size would be 2 * width, height + 1) Write this NV_STEREO_IMAGE_SIGNATURE value Render this texture on the screen My test code skips the first two steps, as I already have a
