Gwyddion – Free SPM (AFM, SNOM/NSOM, STM, MFM, …) data analysis software


gwyfract is a simple Mandelbrot set outside renderer. It uses Gwyddion libraries for false color 2D data display, selections and some infrastructure. Despite being a toy renderer, it has a few cool features:

Source code tarball (bzip2): gwyfract-.tar.bz2
Source code tarball (gzip): gwyfract-.tar.gz

See README in the tarballs for some usage notes.

Compilation requirements

(1) I don't know how to detect the number of processors on MS Windows and namely it's bloody too hard to use third-party libraries (GNU MP) there. Feel free to prove me wrong though. (Yeti)
