PyX (vector Graphics Language)
PyX is a Python package for the creation of PostScript, PDF, and static SVG files. It combines an abstraction of the PostScript drawing model with a TeX/LaTeX interface. Complex tasks like 2d and 3d plots in publication-ready quality are built out of these primitives.https://pyx-project.org/ Its goals are similar to those of other metalanguages for PDF drawing, such as TikZ or Asymptote. PyX is licensed under the GNU GPL version 2. It was originally the graphics library for Pyxplot. Although Pyxplot no longer depends directly on Pyx, it continues to incorporate substantial pieces of the PyX codebase.

Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PostScript
PostScript (PS) is a page description language in the electronic publishing and desktop publishing realm. It is a dynamically typed, concatenative programming language. It was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984. History The concepts of the PostScript language were seeded in 1976 by John Gaffney at Evans & Sutherland, a computer graphics company. At that time Gaffney and John Warnock were developing an interpreter for a large three-dimensional graphics database of New York Harbor. Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. In 1975-76 Bob Sproull and William Newman developed the Press format, which was eventually used in the Xerox Star system to drive laser printers. But Press, a data format rather than a language, lacked flexibility, and PARC mounted the Interpress effort to create a succ ...

Scalable Vector Graphics
Scalable Vector Graphics (SVG) is an XML-based vector image format for defining two-dimensional graphics, having support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999. SVG images are defined in a vector graphics format and stored in XML text files. SVG images can thus be scaled in size without loss of quality, and SVG files can be searched, indexed, scripted, and compressed. The XML text files can be created and edited with text editors or vector graphics editors, and are rendered by the most-used web browsers. Overview SVG has been in development within the World Wide Web Consortium (W3C) since 1999 after six competing proposals for vector graphics languages had been submitted to the consortium during 1998 (see below). The early SVG Working Group decided not to develop any of the commercial submissions, but to create a new markup language that was informed by but not really based on any ...

TikZ
PGF/Ti''k''Z is a pair of languages for producing vector graphics (e.g., technical illustrations and drawings) from a geometric/algebraic description, with standard features including the drawing of points, lines, arrows, paths, circles, ellipses and polygons. PGF is a lower-level language, while Ti''k''Z is a set of higher-level macros that use PGF. The top-level PGF and Ti''k''Z commands are invoked as TeX macros, but in contrast with PSTricks, the PGF/Ti''k''Z graphics themselves are described in a language that resembles MetaPost. Till Tantau is the designer of the PGF and Ti''k''Z languages. He is also the main developer of the only known interpreter for PGF and Ti''k''Z, which is written in TeX. PGF is an acronym for "Portable Graphics Format". Ti''k''Z was introduced in version 0.95 of PGF, and it is a recursive acronym for "Ti''k''Z ist ''kein'' Zeichenprogramm" (German for "Ti''k''Z is ''not'' a drawing program"). Overview The PGF/Ti''k''Z interpreter can be used from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asymptote (vector Graphics Language)
Asymptote is a descriptive vector graphics language — developed by Andy Hammerlindl, John C. Bowman (University of Alberta), and Tom Prince — which provides a natural coordinate-based framework for technical drawing. Asymptote runs on all major platforms (Unix, Mac OS, Microsoft Windows). It is free software, available under the terms of the GNU Lesser General Public License (LGPL). Syntax and notable features Asymptote typesets labels and equations with LaTeX, producing high-quality PostScript, PDF, SVG, or 3D PRC output. It is inspired by MetaPost, but has a C++-like syntax. It provides a language for typesetting mathematical figures, just as TeX/LaTeX provides a language for typesetting equations. It is mathematically oriented (e.g. rotation of vectors by complex multiplication), and uses the 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.

Pyxplot
Pyxplot is a free software command-line graph-plotting and vector graphics package. Its interface is similar to that of gnuplot, but its graphics engine is optimised to produce output in a style appropriate for inclusion in academic journals. The LaTeX typesetting system is used to render all text labels, making it easy to annotate graphs with mathematical expressions. In addition, Pyxplot has many more flow control constructs than gnuplot, making it much easier to perform batch operations. Pyxplot is available for free download under the GNU GPL The GNU General Public License (GNU GPL or simply GPL) is a series of widely used free software licenses that guarantee end users the four freedoms to run, study, share, and modify the software.

GeoGebra
GeoGebra (a portmanteau of ''geometry'' and ''algebra'') is an interactive geometry, algebra, statistics and calculus application, intended for learning and teaching mathematics and science from primary school to university level. GeoGebra is available on multiple platforms, with apps for desktops (Windows, macOS and Linux), tablets ( Android, iPad and Windows) and web. History GeoGebra's creator, Markus Hohenwarter, started the project in 2001 as part of his master's thesis at the University of Salzburg. After a successful Kickstarter campaign, GeoGebra expanded its offering to include an iPad, an Android and a Windows Store app version. 2013 GeoGebra incorporated Bernard Parisse's Xcas into its CAS view. The project is now freeware (with open-source portions) and multi-lingual, and Hohenwarter continues to lead its development at the University of Linz. GeoGebra includes both commercial and not-for-profit entities that work together from the head office in Linz, Austria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
