TerrainSceneManager with OgreNewt

Hi, I read an old post in ogre main forum about an user called bymulker that made a code that integrate terrainscenemanager with ogrenewt.

http://www.ogre3d.org/phpBB2/viewtopic.php?t=9340&highlight=

Is this code implemented in OgreNewt?

Or OgreNewt has already a class that gets the worldgeometry and builds a physic body from that?

I tried to implement my own code using as basis the one that is in wikipedia to PLSM2, but it pretty hard for me.

Thanks for help
