Add callaback interface to InteractionDispatchers

Registered by Václav Šmilauer on 2010-03-15

In addition to 3 groups of functors, InteractionDispatcher would take additional list of callback functors (Derived from IntrCallback). Callbacks would, in succession, receive interaction object after it has been processed by all 3 previous functors (Ig, Ip, Law).

To avoid virtual calls, the functionality would be in static member functions, which receives IntrCallback* self as its first (explicit) argument. A special function IntrCallback::init(Scene*) would return pointer to the function, or NULL if the callback is to be deactivated in this timestep. Dealing with types of InteractionGeometry and InteractionPhysics is responsibility of the functor itself.

In order to make IntrCallback usable in multi-threaded scenario, special OpenMPAccumulator<typename T, T initValue> objects will be created. They will define add, get and reset methods, which will respectively add (for each thread separately), get (summing values over all threads, guarded by mutex) and reset (to initValue, with mutex'ed access) the value.
