We had an arcade/redemption game running on Win98, but hardware which can run it has finally gone obsolete. The game used a number of scaling effects, some through the 3D path, and played some tricks moving things in and out of video memory. If I was to undertake porting it to run on Windows 7, how much trouble would it likely be? Wou...

Any idea how to do it? I am drawing a rectangle that is supposed to be a half-transparent window. I managed to do the transparency by drawing a half-transparent texture, but I also want to blur whatever is under the window. Normally (eg. using GDI) I would create a bitmap of the area, blur it and paint it as the background of my window...
I have developed a custom DirectX UI library equipped with everything from buttons to a gridview. I need a screen-layout editor of some sort. It just takes too long to do it by hand, whether through a config file or hard-coding. I could spend a month or two developing a DirectX editing utility, but I don't have a month or two to spen...

When using the function: D3DXSaveTextureToFile and passing in D3DXIFF_BMP to create a bmp I've noticed that the values seem to be estimated rather than given specifically. Correct me if I'm wrong but a floating point texture can store any float in any given texel which would put it outside the range of a BMP which is stuck between rgb(2...
Hey guys, I need to set a specific pixel in a texture to a custom color, for doing that I made a Bitmap and I always set the pixel in the bitmap, then I recreate the texture from the bitmap. Doing that is very time consuming, is there any way to modify the pixel directly in the texture? ...
So I'm trying to implement some Direct3D post-processing, and I'm having issues rendering to textures. Basically, my program looks like this: // Render scene to "scene_texture" (an HDR texture)... ... device->SetRenderTarget(0, brightpass_surface); device->SetTexture(0, scene_texture); // Render "scene_texture" to "brightpass_texture...

I'm learning DirectX from a book about game programming, and it uses the following method for a game loop: long int start = GetTickCount(); while(true) GameRun(); void GameRun() { if(GetTickCount() - start >= 30) //do stuff } This makes start equal whatever the time is (I'm guessing get tick count gives the number o...

I'm just learning about Flex and I'm loving it. Unfortunatly I still have to make the decision on which RIA technology to use and its dependent on, among other things, from the following case: How can we wrap a java applet around a Flex application?
