Hi Erik, Fred, Thank you Erik and Fred for pointing me to simgear/screen/extensions.[cxx|hxx]...
So it seems all the extensions _ARE_ supported in the default windows DLLS (OpenGL32.dll and GLU32.dll), just NOT exposed through the usual 'export' section, thus the addresses must be 'found/loaded'... If you know any pointers to more documentation on these OpenGL extensions, specifically why this particular 'load' method, that would be great... Anyway, I wrapped the whole thing in a sg_ext_funcs class, so that the address loading is done during instantiation, rather than having to remember to do an 'init' first. I have added this to Atlas's native WIN32 Map program, and had some success - see - http://geoffair.org/fg/atlas-07.htm#framebuf Although there are still some 'color' problems, these images are a _BIG_ improvement to those above them, from using render-in-window... and still a problem of the Release build, which seems to optimize away something very important... Any ideas on these ongoing problems would be much appreciated... But many thanks again...
