#X text 541 578 Here's an example system:;
#X text 44 46 Once you've set up the particle system \, you should
alternatingly bang the link- and mass-bang inlets. The link bang calculates
all forces generated by links and accumulates them into the respective
slots of the mass particles. It requires the time of one audio block
with the size of <max number of links> samples.;
#X text 492 162 Arguments: <name> <number of masses> <max number of
links>;
#X text 525 201 The link and mass numbers must be powers of two \,
like 2 \, 4 \, 8 \, 16 \, 32 \, 64 \, 128 \, 256 \, 512 \, 1024 \,
...;
#X text 525 232 All masses will be active \, but the actual number
of usable masses is one less than specified by the first argument because
the mass at index 0 must not connected with any link (consider it a
"guard mass").;
#X text 42 195 The actual calculations are made on tables \, that are
prefixed by the first argument passed to [physigs]. The tables in the
following subpatch are available (replace the \$0 with the name you
passed):;
