| | | LSynth implement's Larry's string cross section (no use ducking Larry) to create string using the hose synthesis class (this means splined strings with nice smooth curves). I think that a string type that uses pulleys as constraints is important (...) (20 years ago, 26-Apr-05, to lugnet.cad)

| | | | (...) Umm... you REALLY should use a better string element than mine! It is really not very accurate as it doesn't model the three strands at all. It was just a quick hack, and it has fixed colors, if LEGO ever do red or white string it won't work. (...) (20 years ago, 26-Apr-05, to lugnet.cad)

| | | | | | (...) I like Larry's string part better for several reasons. His braid is implemented as twisted surfaces rather than edge lines so it'll show up in both LDRAW and POV. It also uses many less poly's so it'll draw significantly faster. And finally, (...) (20 years ago, 26-Apr-05, to lugnet.cad)

| | | | | | | | (...) LEGO string is a tri-twist. LSynth knows about twisting things (e.g. minifig-chain). LSynth's twist amount/fixed segment is configurable. We could decide what the sortest segment we would ever need and then maybe use 3, 6, or 9 cylinders to (...) (20 years ago, 26-Apr-05, to lugnet.cad)
