Detailed Description template<class T> class NL3D::CIsotropicForceT< T > a helper class to create isotropic force : they are independant of the basis, and have no position (fluid friction for example) To use this class you should provide to it a functor class that define the () operator with 3 parameters param1 = a const reference to the position of the particle param2 = a reference to the position, that must be updated param3 = a float giving the inverse of the mass param4 = the ellapsed time, in second (has the TAnimationTime type). Example of use : class MyForceFunctor { public: /// it is strongly recommended to have your operator inlined void operator() (const NLMISC::CVector &pos, NLMISC::CVector &speed, float invMass , CanimationTime ellapsedTime) { // perform the speed update there } // you can provide a serialization method. Note that that if the functor parameters are set before each use, // it useless to serial something ... void serial(NLMISC::IStream &f) throw(NLMISC::EStream) protected: ... }; because of the serialization process, you must proceed like the following. (but you don't need to redefine serial, which will serilize the functor object you passed for you class MyForce : public CHomogenousForceT<MyForceFunctor> { public: MyForce(); NLMISC_DECLARE_CLASS(Myforce); protected: ... }; not that each functor may have its own parameter. the setupFunctor method will be called each time Definition at line 278 of file ps_force.h.
