485 | This is a new solution, using the ogre engine instead of beeing used by it. |

486 | An alternative solution would be to simply use the timer of the Root object, |

488 | our code without the help of the root object. |

489 | There's even a chance that we can dispose of the root object entirely |

491 | About the loop: The design is almost exactly like the one in ogre, so that |
---|
492 | if any part of ogre registers a framelisteners, it will still behave |
---|
493 | correctly. Furthermore I have taken over the time smoothing feature from |
---|
494 | ogre. If turned on (see orxonox constructor), it will calculate the dt_n by |

495 | means of the recent most dt_n-1, dt_n-2, etc. |
