Unified implementation of the DSI constraints

@inproceedings{MalletRM1992b,
 abstract = { Up to now our researches concerning DSI were focused on the discovery aud the validation of new types of constraints. Each constraint was implemented independently of each other and some updating problems were left unsolved. For example : • both of the fuzzy controllines (FCL) and on Tsurf (OTS) constraintsare shooting on a tsurf playing the role of a target but this cornmon particularity was not taken into account. • if a tsurf is constrained by a fuzzy control line and if the topology of the pline is modified, there was no mechauism for updating the constraints and a there is a good chance ta get a "core dumped". We have now implemented and tested enough types of constraints for having a global view of the problem and it is time ta propose a unified implementation. This is precisely the purpose of the Atomic-Controller model presented in this paper. },
