lol

isnt having orientation = having front and back?
(eg in contrast to moebius-strip / klein's bottle)

talking about the collisionengine (that is i only know tri-tri):

orientation, in the sense of having front and back = normal
and
normal = winding (if no normals supplied by user)
or
normal = user supplied

to wrap it up:
orientation = normal
with optional:
normal = winding

btw: is there an other odelist for this kinda silly stuff :) ?
