• Igor Lemsky what is faster? managed/unmanaged

  I'm a student and just started wih DircetX. And I just wonder, what is better to start with. MY friends says , that managed DircetX is much slowler, but unmanaged is harder to use... I can use C++,c# or VB, so what is better to programming games As managed DX is layered over unmanaged DX it needs more CPU cycles. But this is only a small amount. If your GPU is the limiting factor you will see no difference be ...Show All

• TTruax Windowed Vsync Issues

  Hi, I've had my engine up and running at around 350FPS in windowed mode without vsync. When I enable vsync in windowed mode, and get my 75Hz, I expected it to be perfectly smooth. This is not the case, as every second or two the Present() function takes far too long to return (around 25 ms) - even though the rendering + mechanics part of the app takes less than 3ms. Has anyone else encountered such a problem, and have you solved it ...Show All

• Rama Raman Saving a Volume Texture to a File

  I have some trouble saving a volume texture. The D3DXSaveVolumeToFile Function only saves one level of my 32 layer volume texture (total size: 256x256x32). I tried jpg, png and bmp format. The same happens when I use the D3DXSaveTextureToFile function. Can somebody help Thx. Thanks, will try that. But at least the png format should support layered images. The info of the saved png file supports that: it say de ...Show All

• Azath DirectX AppWizard for Visual Studio 2005

  There is no AppWizard for Visual Studio 2005 in DirectX 9 SDK installation (only for earler version of Visual Studio). Can I download wizard for VS 2005 separately (without all DirectX SDK) or edit avialable wizard for using this in VS 2005 There has not been a DirectApp wizard in the DirectX SDK for at least 1 year now. Instead go to the sample browser application that comes with the SDK, find the EmptyPro ...Show All

• gk41 Problem with texconv and dxtx

  I've written a VB program that creates textures and uses texconv.exe or dxtx.exe to convert from bitmaps to .dds format. It works fine on my main computer. But both utilities fail on my old computer, giving a DirectX error message.   When I try to run dxtx the error message says: "Could not initialize Direct3D.

• hobscrk777 IntelliSense with October DirectX SDK

  Hi. I'm still using Visual C++ 6.0 (still the best imo) and I've just installed the October DirectX SDK and for some reason the IntelliSense doesn't work with ANYTHING from DirectX. Can anyone suggest how I can get it working Thanks in advance. I don't know about the first question, but I have read ( although I haven't personally used it myself ) that the mechanism(s) for adding directories (lib/include/etc.. ...Show All

• Yenan client/server cord system

  I was trying to think of a good way to update clients on other player positions, so I came up with this but not sure how to make it work right right now im sending packets to the server that contain x,y,z info that I get from the camera's EyeLocation, then send the x,y,z from the cameras lookAtPoint but right now the movment looks real chopy so my thought was to use the velocity and the LookAtPoint to update player cords, not sure how to do i ...Show All

• Stigern Forms.Keys vs DirectInput

  I know its probably just me, but is there any reason that OnKeyDown can only process one key down at a time I should add that I am used to using DirectInput for this kind of thing, but I see that it's being recommended not to use it any more, so I tried using OnKeyDown, but when I hold down 2 keys at once, only one gets processed even though my code looks like: if (e.KeyCode = Keys.W) moveforward(); if (e.KeyCode = Keys.A) moveleft(); ...Show All

• Aleydis Help me port a few lines of OpenGL-code to DirectX?

  Hi, Check out these lines of OpenGL-code: Thanks a lot, both. I'm still having trouble working this out...

What is happing now, is that the rotation around the Z and X axis seems to be mirrored, and translation along Y is negated... About inverting Z or the WORLD matrix - is that to make the z-translation part be -z and le ...Show All

• icelock Performance problem with Texture.FromBitmap

  I reduced program boot time (when running from within the IDE) from 12 seconds to less than 1 second by re-writing Texture.FromBitmap using unsafe code.  For me it was easy because I'm only using 32 bit textures and 32 bit bitmaps.  It would be nice to see this function optimized in future releases of the SDK.  BTW, Texture.FromStream has the same problem. -Jeremy I'm having the same problem.
