• limonada Directx.dll version numbering...

  Here at work I had DX SDK summer 2004 installed. And I got a problem with something, so I figured I would try to upgrade to August 2005 to see if that would solve it. But now when I am going to add the DLL files, I started to wonder a bit...take a look at this picture: http://noteme.com/dll.jpg Look at the Microsoft.Directx.dll lines there. Both of them. It says the same version number. Does that mean that there has been NO changes in it the l ...Show All

• Krishna Paripurnam 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 Ah, that helped, thanks. I onl ...Show All

• marla Coping from a render target to a lockable texture

  I've built a GPU based particle system under Windows which works with the exception of one important part. I need to be able to build a bounding sphere off the particle positions. To do this I wrote a shader that samples nearby texels and finds the min/max and writes to a lower resolution texture (right now, the texture gets 4x smaller each pass) until the final size is < 2x2 texels. The idea would then be to copy that render target to ...Show All

• James Su Where did device in direct3D go?

  I'm trying to do some of the real simple DirectX tutorials and when I try to enter the line: Private Dev As Microsoft.DirectX.Direct3d.Device = Nothing or it's equivalent for the C# version I get the error that Device is undefined.

• Unjedai Vsync and timer problems

  It seems that using a PresentInterval of one in windowed mode causes my application to miss frames periodically. About 1/10th of a second every couple of seconds. This doesn't happen in full screen mode. Now what's really weird is that if I hibernate my computer with the program running, when it comes back the windowed mode doesn't vsync at all. I get about 30 FPS with lots of tearing, and Present() taking lots of time (sometimes 40 ...Show All

  I'm trying to do alphablended sprites (not color keyed sprites), but it doesn't seems to works.

• Ronald Wilson HLSL pixel shader: possible to not set output color?

  Is it possible to somehow not set the output color in a HLSL pixel shader without getting an error message It is possible with a CG shader. The effect is a transparent surface at pixels where the output color is not set/computed. Nico Thanks for your suggestion. Maybe I will try that some time. At the moment I just render one object, so I simply set the output color to the background color. ...Show All
