VERY good summation!! I posted something here a couple weeks ago, asking basically the
exact same question. Since this seems to be a popular issue, I'd like to add my vote
to
PLEASE get this fixed as soon as possible!!
In the short term, while we wait breathlessly for 1.3 to come out, does anyone out
there
have any suggestions on how to handle this, preferably a solution that does NOT involve
creating a new strip every time the data changes (i.e. ~30 fps with over a hundred
objects)? I guess we can always use IndexedCoordinateArrays, but I'd prefer to avoid
that if possible...
With all the people here, I assume that SOMEONE would have a clever (==
"not-TOO-kludgy")
solution to this problem!
Thanks, in advance!
