The way that I have done this in the past is to use a pfSwitch node with a
number of children (pfNode's returned from pfLoadFile()). You can then use
the pfSwitch::setVal() method to select the most appropriate LOD to
display at any time. (you can of course add the pfSwitch to a pfDCS node
so that you can control the position and orientation of each object
independently).

I would be interested in hearing further about your work as I am also
working in the area of LOD (the system I have built modulates LOD based
upon an object's size on screen, angular velocity and eccentricity using
models of visual perception). Drop me an e-mail if you have the time.

Cheers,

Martin.
