% This file replaces the standard one in the demos directory.
% This will create 50 PPM frames for making an MPEG movie.
% No other support files are needed.

% To make the frames for the animation, copy this file to a working
% directory (you don't want to overwrite the copy in the demos directory)
% and run KnotPlot as usual.  Click on the Demos / Load Demos buttons,
% then click on the Fig 8 button in the demos panel.  After a few minutes
% you'll have a bunch of PPM frames you can run thru something like 
% mpeg_encode to generate the MPEG file.  An alternative way of generating
% the frames that requires no interaction with KnotPlot is to issue the
% command line:

%       knotplot -stdin < fig8-relax

reset all
