Therion (software)
Therion is free and open-source cave surveying software designed to process survey data, generate maps and 3D models of caves, and archive the data describing the cave and the history of exploration. Therion was developed by the Slovak cavers Martin Budaj and Stacho Mudrak but is available in English. It runs on a wide variety of platforms including Linux, Windows and Mac OS X. Therion is available as part of standard distribution of Debian and Ubuntu (operating system) Linux distributions. It is free software, released under the terms of GNU GPL, with source code available. It does not require any other commercial software to run. The format of all files is human readable plain text (excluding 3D models), which semantically describe the cave, and are compiled by the program into various output forms such as 2D PDF or SVG maps, or 3D models. Other files like map overlays, terrain models and pictures can be incorporated into the output. A graphical editor is provided to help with th ...

Metapost
MetaPost refers to both a programming language and the interpreter of the MetaPost programming language. Both are derived from Donald Knuth's Metafont language and interpreter. MetaPost produces vector graphic diagrams from a geometric/algebraic description. The language shares Metafont's declarative syntax for manipulating lines, curves, points and geometric transformations. However, * Metafont is set up to produce fonts, in the form of image files (in .gf format) with associated font metric files (in .tfm format), whereas MetaPost produces EPS, SVG, or PNG files * The output of Metafont consists of the fonts at a fixed resolution in a raster-based format, whereas MetaPost's output is vector-based graphics (lines, Bézier curves) * Metafont output is monochrome, whereas MetaPost uses RGB or CMYK colors. * The MetaPost language can include text labels on the diagrams, either strings from a specified font, or anything else that can be typeset with TeX. * Starting with versio ...
