    00030     Although the code is original, many of the ideas for the profiler were borrowed from
    00031 "Real-Time In-Game Profiling" by Steve Rabin which can be found in Game Programming
    00032 Gems 1.
    00033
    00034     This code can easily be adapted to your own non-Ogre project. The only code that is
    00035 Ogre-dependent is in the visualization/logging routines and the use of the Timer class.
    00036
    00037     Enjoy!
