[ODE] Building terrain from .flt files

[Thompson, Randy AMRDEC/SAIC]

I've downloaded and checked out Delta3D.  They have an example that uses
ive files for a terrain.  I tried to create one with OSG but it was the
wrong version and not compatible.  I then simply tried to load a flt
file in their example and it worked.  They have OSG's flt reader
embedded down in there somewhere.  I haven't found where they convert it
to a collision geometry yet but at least I know it's there somewhere.
Thanks for the help.
