The goal is to obtain highlighted-points trajectories, while the prototype is dancing. This is possible through a specific computation. The idea is the trajectories will be dancer traces, and subsequently " generative strenght lines" to architectural design.It's usefull to remember the significance of the word "trace":

trace: "to make a plan or diagram," from O.Fr. trasser "delineate, score, trace, follow, pursue" (12c.), from V.L. *tractiare "delineate, score, trace" (cf. Sp. trazar "to trace, devise, plan out," It. tracciare "to follow by foot"), from L. tractus "track, course," lit. "a drawing out," from pp. stem of trahere "to pull, draw" .Meaning "to pass over" (a path, etc.) is attested from c.1381. Sense of "draw an outline of" is first recorded 1390. Meaning "copy a drawing on a transparent sheet laid over it" is recorded from 1762. trace (n.1) "track made by passage of a person or thing," c.1300, from O.Fr. trace, back-formation from tracier (see trace (v.)). Scientific sense of "indication of minute presence in some chemical compound" is from 1827. The verb in the sense of "follow by means of traces or tracks" is recorded from c.1450. Traces "vestiges" is from c.1400. Tracer "bullet whose course is made visible" is attested from 1910. trace (n.2) "straps or chains by which an animal pulls a vehicle," c.1300, from earlier collective plural trays, from O.Fr. traiz, pl. of trait "strap for harnessing, act of drawing," from L. tractus "a drawing, track," from stem of trahere "to pull, draw" (see tract (1)).
