The ROAM engine is not going to happen. CLOD terrain is the way of the
future, with almost all engines abandoning the mad popping of ROAM for
the much more appealing and less CPU intensive methods. Almost all
engines are CPU bound and have plenty of GPU left over, so it's a clear
indication we just can't spare the CPU cycles.
ROAM was cool and a good excercise, but it's just not worth it anymore.
Let's put it behind us.
Anyway, to address the ripples, we have two types of geometry in our
maps: static and dynamic. Static geometry can not be changed in real
time, but we can manipulate the vertices of dynamic geometry. We're not
using it for anything right now and it's possible the code is broken,
although likely easy to fix. That's what TSolid is for. Ripples
shouldn't be a problem.
