Hallo,
attached is a little summer holiday toy by me: a set of two physical modelling abstractions that implement a 1-dimensional mass and link similar to pmpd's masse/link objects. However they don't require or use any externals at all! (Except "expr" which is almost an internal.)
phys.pd is an example for using "emass1" and "elink1". Everyone who ever has used pmpd will feel right at home, although I use a slight different syntax for setting and getting attributes. But you can change that easily of course to fit your needs. Maybe 2-, 3-, and 4-dimensional models follow later. ;-)
Have fun.
