The simple C program chirikov.c produces .ppm picture files of
arbitrary high quality. Want to see the phase space in a 5000x5000 pixel
resolution? Go ahead: chirikov -w 5000 >out.ppm does the job. Attention:
this will produce a file of 75 Megabytes! The default size is 500x500 pixels.
Included in the distribution are some shellscripts which
illustrate how to use chirikov to build more complex programs
like for example to make and render movies.
Included is also a small filter program ppmchirikov.c
which allows you to let the
chirikov map act as a filter on any image file.
Also this C code is kept simple (less than 100 lines) and can thus
serve also as a template for other filter programs which can coexist
with the handy netppm routines.
