GDI OpenGL composition
-
Hi, I'm trying to mix Device Contexts and OpenGL but not the usual way. I don't want to draw with GDI on top of an OpenGL scene. What I wanna do, is apply an HDC bitmap as a texture on an OpenGL polygon. I know that this is generally a bad idea, but if you know anything about how is that possible, you would be very helpful. I'm coding on C/C++ on Win32. A DirectX 8/9 solution would also be appreciated.

Finally found the solution myself. If anyone else is interested in that, the process is simple. You create a bitmap from the DC (there are many websites that describe this), and then you apply that BITMAP object as a texture, the way you'd apply any other bitmap texture.
