vfplot is a software for plotting 2D vector fields.
Features:
- 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 is new in this release:
- This version sees a rewrite of the multi-thread code, resulting in a substantial speedup on multi-processor hardware.
- Additionally, the supporting gfs2xyz2D utility was updated to the latest version of the Gerris library.
What is new in version 1.0.7:
- A buffer overrun was fixed.
What is new in version 1.0.5:
- Output to the POV-Ray scene language.
What is new in version 1.0.4:
- This release adds a graphics-state cache for easier final adjustment of line widths, fill colour, etc.
- It adds read support for Matlab binary files.
What is new in version 1.0.3:
- Simplified potential used in the dynamic (removal of the attractive tail) allows a reduction in the number of neighbors and speeds up the dynamic by around a factor of two.
- Plots look cleaner.
- Several bugfixes and minor feature enhancements.
What is new in version 1.0.2:
- Added a --glyph option for alternative glyphs. New wedge and triangle glyphs.
- Added a --aspect option to adjust the aspect (the ratio of length to width) of the glyph.
