Yes of course. There has been a long ongoing discussion about how best to implement Hyperdoc and Axiom Graphics on Windows because of this issue. X11 is required because both HyperDoc and Axiom Graphics call X11 library functions directly when creating windows and drawing to the screen. > Axiom was also sold on Windows if I am not completely wrong. You are correct. > How did NAG produce graphics there? NAG integrated two new packages for Axiom on Windows - one called OpenInventor (for graphics) and the other Techexplorer (a latex-cable browser to replace Hyperdoc). Both of these packages were proprietary at the time Axiom was made open source but now they are (more or less) open. OpenInventor is now called 'Coin3d'.

Axiom Graphics is a separate program written in "C" that does all of the interaction with X11. AXIOMsys (which is the program that runs the code at which you are looking) sends commands to Axiom Graphics via a session socket. > But I really really wonder, why X is a must for draw and/or > write.
