repel - equilibrium of points repelling on a sphere

Usage

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, -1 for unlimited (default: -1)
  -s <perc> percentage to shorten the travel distance (default: adaptive)
  -r <exp>  repelling formula, 1/distance^exp (default: 2)
  -l <lim>  minimum change of distance/width_of_model to terminate, as 
               negative exponent (default: 12 giving 1e-12)
  -z <nums> number of iterations between status reports (implies termination
            check) (0 for final report only, -1 for no report), optionally
            followed by a comma and the number of iterations between
            termination checks (0 for report checks only) (default: 1000,1)
  -o <file> write output to file (default: write to standard output)

Examples

repel -N 24 -l 15 | conv_hull | antiview

repel -N 24 -s 1 -l 15 | conv_hull | antiview

Notes

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.
