OK, before i can think more, i need to ask, what are realistic values of N here?
Is N always known at compile time or are you talking about a runtime N as in:
DualQuat s = 0;
for(int i = 0; i < N; ++i) s += w[i] * Q[i];
s.normalize();
?
For the runtime N case, I think that the user must take care of the
optimization, i don't see how we can do that.
For compile-time-fixed N, N can't be very big, right? How big?
