Usage: repel [options] [input_file]
An equilibrium position is found for a set of points which repel each
other. The initial coordinates are read from input_file if given (or
from standard input), otherwise use -N to generate a random set.
Options
-h,--help this help message (run 'off_util -H help' for general help)
--version version information
-N <num> initialise with a number of randomly placed points
-n <itrs> maximum number of iterations (default: no limit)
-s <perc> percentage to shorten the travel distance (default: adaptive)
-l <lim> minimum distance change to terminate, as negative exponent
(default: 12 giving 1e-12)
-r <rep> repelling formula
1 - inverse of distance
2 - inverse square of distance (default)
3 - inverse cube of distance
4 - inverse square root of distance
-o <file> write output to file (default: write to standard output)
repel -N 24 -l 15 | conv_hull -o snub_cube.off
repel -N 24 -s 1 -l 15 | conv_hull -o snub_cube.off
The progress report includes the number of iterations, the greatest distance moved by a point, the shortening factor, and the sum of all the forces.
If adaptive shortening is used then there is also a line of figures showing the number of times out of ten that the shortening factor was increased.
