Freeware Descriptions:
Asymptote is a powerful descriptive vector graphics language that provides a natural coordinate-based framework for technical drawing. Labels and equations are typeset with LaTeX, for high-quality PostScript output.
Here is complete features (taken from authors site):
A major advantage of Asymptote over other graphics packages is that it is a programming language, as opposed to just a graphics program.
Features:
- provides a portable standard for typesetting mathematical figures, just as TeX/LaTeX has become the standard for typesetting equations.
- inspired by MetaPost, with a much cleaner, powerful C++-like programming syntax and floating-point numerics;
- runs on all major platforms (UNIX, MacOS, Microsoft Windows).
- mathematically oriented (e.g. rotation of vectors by complex multiplication);
- LaTeX typesetting of labels (for document consistency);
- uses simplex method and deferred drawing to solve overall size constraint issues between fixed-sized objects (labels and arrowheads) and objects that should scale with figure size;
- fully generalizes MetaPost path construction algorithms to three-dimensions;
- compiles commands into virtual machine code for speed without sacrificing portability;
- high-level graphics commands are implemented in the Asymptote language itself, allowing them to be easily tailored to specific applications;
