I understand your problem. You are trying to figure this out by disassembling and reverse engineering microsofts binaries, literally trying to read every functions in implementations and everything by letter to letter in excamples. You should actually use a different approach to this problem, and …

The ICD, supplied by the graphics card manufacturer, are being called by opengl32.dll, which is basically a generic mcd. This is simply terminologically flawed. MCD (Mini Client Driver) is just another driver model for OpenGL implementation on Windows. Which was easier to forge than ICD, but less …

Ctrl+F "In the current implementation of the DDK". microsofts opengl32.dll is not an implementation of the opengl api opengl32.dll is a component made by microsoft which sole purpose is to detect the opengl driver of your video card based on registry keys. then it loads the file, passes the …

The code for opengl32.dll is very clear that the call to GetSurfaceFromDC must succeed for the code path leading to DrvCreateDirectDrawContext to be called. Logically since no public drivers expose the entry point, and the fact that if GetSurfaceFromDC succeeded then the entry point has to exist …

Without a more up to date ICD DDK I don't think you're going to get any definitive answers though I'm afraid. It's very unfortunate that OpenGL driver databases like gpuinfo.org never seem to register the functions exported by ICD in their reports. :( Given that you've not found a public driver …

Hi hornet1990 , happy to encounter you again here. %-) The logs you found are the OpenGL32.dll calling GetProcAddress for the function, but not finding it (returned NULL) so all that confirms is that the ICD on those machines didn't export it. This occurs in a function that loops trying to get the …

Well, this one might be quite obscure, but let's try, why not. Many people know that OpenGL in Windows has always used DirectDraw (and previously DCI) to manage video memory. But far fewer know that WGL could also create contexts based on such surfaces, implying IDirectDrawSurface::GetDC() to …

Windows 95 didn't have one until MS released the OPENGL95.EXE addon, but I think it is the 1.1 API, similar to the software renderer in NT 4. You're right, I checked the original release and it doesn't have an implementation although OSR2 does (the 1.1 implementation). It's actually much more …

Video: NT 3.50 and 3.x don't support OpenGL and 3.51 doesn't support OpenGL 1.2, so SDL would use WINDIB which means GDI. This is not entirely true - OpenGL 1.0 appeared in Windows 3.5 "Daytona", then extensions were added in 3.51 "NewShell", and version 1.1 became available in 4.0 "Cairo". …

This sound was added to Doom2D Forever 20 years ago to indicate the highest level of damage to the player. It is recorded in 11025 Hz 8-bit mono and seems to be interpolated, suggesting it was recorded directly from the game itself. Unfortunately, none of us remember the exact origin anymore. But …
