[ As suggested by The Grand Marshal of Libraries (tm), I'm moving a thread from the HOpenGL list to this one, widening its scope a bit. ] The currently proposal for the Graphics hierarchy looks like this (IIRC): Graphics UI Drawing Format I propose changing "Drawing" to "Rendering", because this a more common term in computer graphics. But I'm no native speaker, so I'd like to hear some comments on this. Another problem is that in "real world" APIs the above subcategeories are often mixed up a bit. Have a look at the following APIs resp. Haskell libraries: Clean ObjectIO Direct3D FRAN FranTk Fudgets Functional Metapost GIFWriter GLUT GTK+ Haven HGL Inventor MOTIF OpenGL Pan TclHaskell Win32 X toolkit intrinsics Xaw Xlib Xmu Where should we put them in the new hierarchy? Do we need more/other subcategories?
