Most simple question

Hi,

I was wondering that anybody asked for the simplest question ? How it's integrated ?
Maybe some problems are because there is no knowledge about integration beetwen graphics engine and physics engine.
Where're points where this two are connected and talking ? How for example physics actors are moved when mesh'es are moved ? Let's say for example ogre + physx or nxogre.
I wrote some lines of code but I can't describe this or explain. Can somebody do this ? - maybe this help.

In the most part; NxOgre does that for you - via the body class.

Yes, I've seen body class - if I remeber form you site where was described inheritance of an actor class.
But if I would like to make a ragdoll I can use body too ?

a ragdoll would be several actors.
