• kundalani MDX2 and Action Mapping?

  Can anyone direct me to documentation on using Action Mapping via MDX in the latest release of the DX9 SDK (Feb) Searching has proved mostly fruitless and DX8 samples of AM (using DIACTION, etc) are useless as it appears the entire structure has changed. I've looked through the SDK docs but they are simply a shell outline and only list classes and their members - there is little to nothing in the way of description and zero examples. Also, a ...Show All

• hypermegachi Windows Game Testing standards

  Hi, I'm looking for a set of standards to QA test a game against. Actual gameplay aside, we're interested in making sure the game performs admirably in the 'Plays well with Windows' category. To give a few examples: Alt-ENTER should switch from Full Screen to Windowed mode. Clicking the game in the taskbar should minimize or restore it. The game should regain focus properly when Alt-TAB is used. There are all kinds of little th ...Show All

• Sung M Kim rendering multiple video streams

  I'm developing an application which displays 4 (or even more, if possible) video streams simultaneously in real-time (30 fps per stream). I need a renderer that will take the raw YUV frames and display them to a Win32 window, scaling as required. Each stream is independent of the others, including running in separate threads. Currently, my app has an independent DirectDraw-based renderer for each stream (written by someone else), but performance ...Show All

• jcoburn SetClipPlane ????

  Hi, I'm trying to create a mirror. I got the render to texture thingy done. I'm first using the technique of calculation the "virtual camera" position behind the mirror, then render the scene from that position. I need to somehow "clip" the scene to the boundaries of the mirror, so i guess theres two ways to do it. One is to set the clip planes using device->SetClipPlane(...), but ... help ... help :) :)        ...Show All

• Nick Rawe D3DXOptimize Faces/Vertices

  Does anyone know how to use D3DXOptimizeFaces and D3DXOptimizeVertices I'm just a little bit confused as to what the SDK documentation means, and how the functions actually work. Do the functions modify the index buffer for me or do they expect me to reorder it myself using the remapping What's the format of the remapping If someone's got a code sample of these functions being used properly that would be great. Thanks, Phill ...Show All

• Lee18 DX sdk 2005 october and vs2005

  As far as I can tell, the october version of the sdk should have support for net 2.0 and as such is updated for vs2005. The question is then why the installer can still not recognize that you have vs2005 installed and thus let you add the visual studio integration. It seems that you need to install BOTH vs2003 and vs2005 to have this integration. If you do this then you (that means I) experience that the shader debugger when run from debug/direc ...Show All

• SreeReddy Anti Aliasing in Textures

  I am trying to use DirectX9 to draw into one texture and then use that texture in another scene. My problem is that any antialiasing that is done when drawing into the texture is lost when I draw the texture in the new scene. Here is some code that demonstrates the problem: void RenderScene(HWND hwnd) { RECT clientRect; GetClientRect(hwnd, &clientRect); if (s_pD3D == NULL) return; IDirect3DDevice9* pDevice = NULL; IDirect ...Show All

• Emadkb Dramatic memory leak in DrawText

  I've been banging my head against the wall for the last few days trying to track down the source of a rather big memory leak in my Direct3D-application. Turns out the culprit seems to be the DrawText function. Let me explain exactly what happens: I'm using a variable width truetype font (Times New Roman) created through D3DXCreateFont. I'm using this in various parts of my application, but the part where the problems are easiest to notice is ...Show All

• dotnetboy pixel shader computation: precision problem?

  Hi, I do the following computation in a pixel shader:   const float texel = 1.0 / 128.0; result = floor(In.texcoord.w / 16.0) / 64.0 + texel   In.texcoord.w containes an integer value between 0 and 299, stored as a float, interpolated over the triangle, where each vertex stores the same value, so in practice there shouldn't be any interpolation happening.  When I output result as a color, I notice distortions ...Show All
