Full screen rendering on widescreen monitors
My situation is as follows. I make games that use fixed size backgrounds (say 800x600). When players go fullscreen in a widescreen monitor, I add black bars to the sides, to make sure the game doesn't look stretched. There are several ways to do this, though, and I wonder what's the best approach : 1) Find a resolution that closely mat...

Application crash without any kind of Exception
I have a multithreaded .Net C# application, it uses Direct3D 9/10 and XAudio2. (Direct3D is accessed by only one thread, same for XAudio2. Direct3D isn't the problem cause the error is manifest in either DX9 or DX10 mode without any change in its behaviour.) Sometimes (there are some areas that gives this problem randomly) this applicat...

How do I set up DirectX 9 so that backface culling is off, z-buffering is on, and gouraud shading works, for triangle meshes without normals data?
I've been having difficulty identifying the correct parameters for the PresentParameters and DirectX device, so that there can be both vertex-level gouraud shading and the use of a z buffer. Some triangle meshes work fine, others have background triangles appearing in front of triangles which are closer-to-camera. An example of this is ...

IDirect3DDevice9, setting how textures scale?
In Photoshop you can control how pictures are scaled up and down as 'image interpolation', it has different options like 'Bicubic', 'Bilinear', 'Nearest Neighbour' and such. I was wondering if I could do something similar in DirectX? Basically if I slap a texture on a quad and stretch the quad how can I control how the texture on the qu...
In DirectX 9, how to get zbuffer to work properly?
I've been unsuccessful at getting a simple cube geometry with shading turned on to display correctly. This is c# code, but the values are being passed through SlimDX directly to C++ code. pParams.BackBufferWidth = 0; pParams.BackBufferHeight = 0; pParams.BackBufferCount = 1; pParams.BackB...

Can I expose the necessary interface from my renderer to a C# app, without managed...
