Depending on the selection and + * ordering of the operator many known subdivision schemes can be + * created. + * + * Every rule inherits from RuleInterfaceT and is represented out of + * the subdivider object by a RuleHandleT (as usual within + * %OpenMesh). You can add rules using the CompositeT::add() + * functions. The correct order of adding the rules is very + * important, and furthermore not all rules get along with each other + * very well. (Please read the given literature, especially the + * paper by Oswald and Schr�der.) + * + * To use a composite subdivider first define a rule sequence + * describing the order of execution of the rules. In the order the + * rules habe been added they will be executed. E.g. the rules given + * in operator notation have to added from right to left. + * + * After the rule sequence has been defined the subdivider has to be + * intialized using CompositeT::initialize().
