vfplot Description

A program for plotting two-dimensional vector fields vfplot is a software for plotting 2D vector fields. Here are some key features of "vfplot": Large arrows: · The idea of vfplot is to plot vector fields with relatively large arrows — large enough to be perceived individually Curvy: · For large arrows to accurately represent the field they need to follow it in their shape; vfplot uses simple circular arcs Placed apart: · Placement of large arrows on a regular grid would limit the dynamic range possible; vfplot places the arrows via a packing of their bounding ellipses Field input: · Fields can be specified by data in a number of formats: a simple ASCII grid format, Gerris gfs files, or a pair of GMT grd files. Several test fields are built in and adding another is straightforward if you have a little C experience Vector output: · Output is in the PostScript format which can be converted to SVG, PDF and other vector formats with standard tools. The files are small, typically a few tens of kilobytes Limited in scope: · The vfplot program plots only arrows, it will not be a general purpose plotting program Free software: · Released under the GNU GPL v3, contact the author for other licencing What's New in This Release: · Output to the POV-Ray scene language.
