Adaptive Composite Subdivision framework.
The adaptive composite subdivision framework is based on the work done by P. Oswald and P. Schroeder. This framework elevates the uniform case of the composite scheme to the adaptive setting.
For details on the composite scheme refer to
For details on the transition from uniform to adaptive composite subdivision please refer to
In the composite scheme a subdivision operator is created by combining smaller "atomic" rules. 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(). If everything went well, use CompositeT::refine() to subdivide locally a face or vertex.
