interface and register it in you scene manager via ISceneManager::registerSceneNodeAnimatorFactory.

Note: When implementing your own scene node factory, don't call ISceneNodeManager::grab() to
|
|
increase the reference counter of the scene node manager. This is not necessary because the
|
|
scene node manager will grab() the factory anyway, and otherwise cyclic references will
|
|
be created and the scene manager and all its nodes won't get deallocated.
