Asymptote is a powerful descriptive vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications. License: GNU General Public License (GPL) Changes: The speed and functionality of the graphical user interface has been greatly improved, with a zoom feature and full transparency support under MS Windows. The intersections routine was fixed. The 2D and 3D graph routines were improved. Degenerate 3D reference vectors are now handled. A marker dot routine was added. A history(int n=1) function can be used to return the interactive history. Locale bugs were fixed. A string[] split function was added. Installation, uninstallation, and diagnostics under MS Windows were improved. The output(s,update=true) function was fixed.
