PyFeyn Description

A free Python-language based system for drawing Feynman diagrams PyFeyn was inspired by the C++ FeynDiagram system, and aims to provide the same functionality and quality of output as that, with the added benefits of a modern interpreted language, an improved interface and output direct to both EPS and PDF. Feynman diagrams are important constructs in perturbative field theory, so being able to draw them in a programmatic fashion is important if attempting to enumerate a large number of diagram configurations is important. The output quality of PyFeyn diagrams (into EPS or PDF formats) is very high, and special effects can also be easily obtained by using constructs from PyX, which PyFeyn is based around.Behind the scenes, PyFeyn uses the excellent PyX system - you can use PyX constructs in PyFeyn diagrams if you want, too.
