(...) I guess points are shared only on a part basis, not on a model basis. So, 400 distinct points for a part is already a fair number. Thus I think the sorting technique I discuss is not candidate for implementation unless the ldraw library goes (...) (21 years ago, 7-Jul-03, to lugnet.cad.mlcad)

(...) Thanks Michael. So, at loading time, each added point has to be compared to all points in the point list. Does this impact the loading time of big parts or big models in a significant manner? Or is it only minor slowdown? Regards, Damien (21 years ago, 5-Jul-03, to lugnet.cad.mlcad)
