[Opensim-dev] physics interface / Re: OpenSim beginner question

[Teravus Ovares]

That's actually the "easiest description to understand" version.
The longer and more truthful version..   is 'Simulate' is run within
the thread context of the heartbeat thread in the region.   Having
changes applied during that time does not require extensive locking
because we know, for sure, that only a single thread will be making
the changes during that time.

Best Regards

Teravus
