| I'm trying to use opengl multisampling in an FxPlug and I keep hitting deadends.
a) GL_EXT_framebuffer_multisample isn't yet implemented (at least on my hw)
b) I've set up a pbuffer with a multisample pixel format (GL_SAMPLE_BUFFERS = 1 and GL_SAMPLES = 4, and enabling GL_MULTISAMPLE) but no antialiassing is being done . http://lists.apple.com/archives/mac-opengl/2005/Oct/msg00074.html suggests multisample pbuffers aren't supported and suggests solution c) - which does work in an app, but cannot be used in an FxPlug.
c) I cannot use a hidden window with an NSOpenGLView (created with multisample pixel format) as the shared context passed to the FxPlug is a CGLContextObj which it seems can't be used with the windowing system.
It surely must be possible somehow? Any help to get me on the right path is appreciated!
Thanks Gary
