Do you: Need to have your viewpoint move quickly, while rendering
with nontrivial terrain detail?  If so, do not bother with any kind of
frame-coherent CLOD (including any version of ROAM).

In fact, I am still waiting for people to understand that frame coherence is
to be avoided in games whenever possible.  I am going to submit a siggraph
presentation on that (and some other things) for next year.
