Also, if the constrained point is redefined so that it is no longer constrained to any curve, this is a major problem, because it would tqinvalidate the locus. Another point is that in practice, the locus depends on more objects than its -tqparents alone. This is not a good thing, because it makes it +parents alone. This is not a good thing, because it makes it impossible to optimise drawing of the objects, using the information about which objects depend on which others, because this information is invalid. |
