I am looking into the new combined OpenGL 3D rendering and SDL 2D
blitting capabilities… This functionality is made available through
the use of SDL_SetVideoMode with the SDL_OPENGLBLIT option.
I noticed in a few demos that any alpha information is say a surface
that is being blitted is lost when using the SDL_OPENGLBLIT mode. A
couple questions -
Currently is there anyway to make this work without going entirely to
OpenGL (i.e. glDrawPixels or glTexImage2D ) so that a 2D blitted SDL
surface “blends” with an OpenGL rendered scene?
If not, any chance at getting this added or at least a pointer to where
would be a good place to start???
Open to all suggestions…
